After Labor Day, summer is effectively over for investment professionals. Most executives and senior staff of financial services firms return to the office from vacations recharged and ready to go. Next week, they may need to tap that extra energy if they have to cope with the conversion of TD Ameritrade accounts to Schwab accounts. Schwab Advisor Center will be temporarily unavailable from September 2nd at 2am ET through September 5th at 5am ET while they complete the integration between Schwab and TD Ameritrade.

Earlier this summer, Schwab stopped generating transactions and positions, as well as other files that were scheduled to be sunset. Schwab gave customers over a year of warning that this change was coming. However, I cannot help wondering how difficult it would have been to keep generating those files, or better yet, refer those customers to me directly for assistance. Schwab wasn’t interested in doing either. As a result, customers that were impacted may still need to update or change systems that were dependent on those data feeds for daily workflows in order to process the transactions and positions data received after 07/11/23.

 

 

Creating Price Files Compatible with Advent Products

When I blogged about Schwab ending support for legacy price and transaction files around this same time last year, I didn’t know if I would be willing to create a translation utility to take Schwab CRS transaction files and convert them to Advent’s CS transaction files.  Writing the utility for prices was relatively simple by comparison.  I collected a one-time service fee from customers, and in turn facilitated their ability to keep their pricing workflow intact through the use of that utility. The utility processes CRS security files (CRSyyyymmdd.SEC) to create CS price files (CSmmddyy.PRI). Once the CS files have been created, they show up in Dataport as they always have in the past.

I felt good about the fact that I was able to help those customers in very tangible way with little effort on my part.  If you haven’t read the blog, you can find it here.  In short, the blog details the issue at the time, some possible solutions, and warns users that the conversion of transactions will be a larger and more costly issue to address.  At that time, I was not committed to writing a transaction conversion utility.

I have included a rudimentary VB code sample below to translate Schwab’s newer CRS SEC file to the legacy CS PRI Advent format required by some users:

 

VB
Sub CreatePriceFile(Folder As String, FileDate As Date)

'This subroutine converts Schwab CRS files to Advent's
'naming convention (CSmmddyy.PRI) and file format to be
'compatible with Axys and Dataport.  This is the same format
'that was provided via the Schwab Point-to-Point interface.

'Once this routine has been run on a CRSyyyymmdd.SEC file, 
'Dataport will recognize and be able to convert these files
'as it did prior to Schwab turning off the feed. 

' written in VBA by Kevin Shea (aka AdventGuru) & updated 08/30/2023

' Disclaimer: This routine works fine for the specific instance it was
' created for, but could need additional modifications for different
' circumstances.

CRS Transaction File Translation

As the July 2023 deadline imposed by Schwab approached, some of the users I assisted with the CRS Price File Translator reached out to me to see if I was going to create a tool to address it. Eventually, I agreed to do it in July.  Working from samples of the first customer’s historic CS transaction files (CSmmddyy.TRN) and the newer Schwab CRS transaction files (CRSyyyyddmm.TRN), I was able to map over fifty different types of transactions and build a tool to convert the CRS files provided by Schwab into the format compatible with Advent and Dataport. 

There is some redundancy in Schwab’s transaction mappings.  Schwab seems to create a distinct transaction code and mapping for more transactions than necessary. For example, there are at least six different types of dividend mappings and similarly at least three different ways that they categorize a check that was written.  My goal in writing the translator was to preserve the information and create a file nearly identical to what Schwab has been generating for several years.

 

The CRS Position File

When I agreed to create the conversion utility for transaction files, I failed to realize that I would also have convert the position files so that users can continue to utilize the Schwab Reconciliation Report in Advent. So I created the position translator gratis.  While analyzing the file I found that Schwab has two different record types encoded in their CRS RPS files. The first block of records appears to be non-cash assets.  The second block of records are cash-only. Those records start with “D1” and “D2” respectively.

Those familiar with Schwab’s cash types may already know that they have nearly twenty different types of “cash” that get baked into the position files.  The CRS RPS file has the asset value for these various cash types for each account stored in a single record, which means that we needed to read the cash records from the CRS file and create multiple records in the CS file.  Conversely, the non-cash records are translated into a single record in the CS file we created.

The tool has been used to convert the transactions and positions from 07/12/23 forward.  It is now being used in day-to-day operations at that firm.  There have been a small number of mapping issues we needed to fix, but overall, the CRS Translator – which now creates CS PRI, TRN and RPS files – is working well.  In the past week, I signed up a few additional customers for the service and expect to hear from more potential customers due to the upcoming Schwab/TD Ameritrade (TDA) work scheduled for Labor Day weekend.

 

What is going to happen to AD files currently generated by TD Ameritrade?

Apparently, Schwab will stop providing similarly constructed legacy files to the TDA advisors.  My understanding is that those Schwab customers will receive CRS files populated with their data for the first time on 09/05/23.  They have been receiving empty files with headers alone to date. If their workflows have any dependencies on the old file formats, they will need to convert those files ASAP or make other changes to their systems to implement new workflows, such as ACD, so they can continue to download prices and transactions and reconcile positions in a timely manner.

With my long-standing history as a seasoned and impartial technology consultant catering to the wide-ranging needs of Advent users, it should come as no surprise that companies that have moved away from Advent call me to assist them if they have Advent specific needs after their agreements with Advent have lapsed.  In those specific cases, I suspect my independence from Advent is one of the most appealing features of my service, but many Advent users that have ongoing agreements with Advent also retain me to provide a level of service that Advent seems unwilling or unable to provide.

One of the things I get regular calls about is getting Axys running again.  These calls occur either when firms upgrade their servers or when firms that have moved on to competing Portfolio Management Systems dust off their old Axys files with hopes of tapping into Axys again.  My experience consulting to financial services firms using Advent Software for thirty-plus years facilitates my ability to resolve issues like these easily. 

Many of those calls I get start with the caller telling me, “We reinstalled Axys on the server and it isn’t working.”  And inevitably, this tells me more about the underlying issue than the caller ever could.  You certainly can reinstall Axys, but you probably don’t need to because Axys on the server is just a bunch of files that you access from another PC.  The most important thing to keep Axys working properly aside from the proper installation being done (at some point in the past) is making sure that users have all necessary rights to the shared folders.

This article is focused on explaining what the requirements are to empower you or your firm to resurrect Axys.  As usual, I’ll be providing a level of information in this piece that may be more than you need to solve any immediate problem with the hope that info is useful to you in the future.

Axys Versions

There are two fundamental versions of Axys: the multi-user version and single-user version.  To add a little confusion, the multi-user version is frequently referred to as the network version, but both fundamental versions are regularly installed on networks.  So, the network version is a bit of a misnomer.  Among these two fundamental versions, there is also the version of the software, which is at this point typically version 3.8, 3.8.5, 3.8.6 or 3.8.7.  In addition to these, there are also Monocurrency, Multicurrency and Variable Rate versions, to name a few.  Suffice to say, there are a lot of different versions.

Axys Licensing Model

The concurrent licensing model that Axys implements applies to both single-user and multi-user versions.  In both instances, the number of real Axys users typically exceeds the total licensed users, but having a multi-user version allows more than one user to use Axys simultaneously and adds certain multi-user features, such as user-specific settings and separate blotters, et cetera.

Understanding How Axys is Installed

Initially, the single-user version is simpler to install because the primary program (Axys) and supporting programs (Dataport, Data Exchange, Report Writer, et al.) hypothetically only need to be installed once.  That would be true if there literally was only one user using the software on one PC.  In actuality, the single-user version of Axys and supporting programs get installed multiple times in a network environment. They need to be installed once for every user, albeit to the same destination for each user (e.g., F:\Axys3).

During the Axys install process, certain required files are copied to the user’s PC and/or profile and Axys creates registry keys in HKEY_CURRENT_USER\SOFTWARE\Advent.  The most critical Axys registry keys are stored in HKEY_CURRENT_USER\SOFTWARE\Advent\Axys\3.  Although there are several important Axys files, the firmwide.inf is perhaps the most crucial file.  In a single-user installation, this text file, which can be found in the root folder of Axys (e.g., F:\Axys3), details certain settings in use and where all of the other Axys files can be found.

The multi-user version must also be installed multiple times for users, but the initial Axys install varies.  You install it once to the network/primary destination folder (e.g., F:\Axys3) and then install it again for the rest of the users (e.g., F:\Axys3\users\kevin where a firmwide.inf file will be created).  Similar to the single-user version, the supporting programs such as Dataport, Data Exchange and Report Writer would also need to be installed if the user needs those, or if you are trying to make sure all of the users have access to all of the supporting apps. The same registry keys are used for the multi-user install as the single-user version, but the multi-user (a.k.a. network) version adds an additional critical file: the netwide.inf file.

Netwide.inf versus Firmwide.inf

These two files are closely related.  The netwide.inf file should only be found in the root Axys folder of a network install, but firmwide.inf files exist in both single-user and multi-user environments.  The multi-user version is designed to use the settings in the netwide.inf as the system default and have any settings in the firmwide.inf supersede the settings in the netwide.inf.  As a rule, you should never see a firmwide.inf in the root Axys folder of a network install.  You should also almost never see a netwide.inf file in the root of a single-user Axys installation.


A Recurring Axys Installation Bug

With regard to installing Axys, there is a rather annoying issue that has been going on for several years.  It seems that the Axys install will not recognize certain network locations and/or mapped drives.  The fix requires the following registry settings:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]

“EnableLUA”=dword:00000001

“EnableLinkedConnections”=dword:00000001

Once those settings have been applied, the Axys install program will be able to find the mapped drives.  It seems to me that this is an issue Advent should have addressed a long, long time ago.

Understanding Those Axys Shortcuts and Corresponding Registry Entries

The working folder of the Axys shortcut needs to point to the appropriate folder for the firmwide.inf file.  That means that an Axys shortcut for a single-user version of Axys should have a “Start in” folder like F:\Axys3, whereas the multi-user version would have “Start in” folder like F:\Axys3\users\kevin.  Assuming the same install folder was used, the target for these shortcuts would be the same: F:\Axys3\Axys32.exe.  Likewise, the registry entries associated with Axys should match these settings.  When I am looking at a system, I can usually determine if Axys has been installed properly by looking for consistency between the shortcuts and the following registry entries: ExePath, NetPath and UserPath.

In summary, your Axys install is dependent on a few things: the files themselves, access to the location where they are stored and proper mapping to the location of those files in the registry, firmwide.inf and netwide.inf if applicable.  Hopefully, you can get things back online on your own, but if you need assistance with your Advent installation, reach out to me and I’ll do my best to assist you.

Schwab is no longer providing price file downloads that some Axys users have relied on for decades.

When I set out to write this, I had some trouble deciding on the title.  At first, I considered “Schwab Hamstrings Pricing for Advent Users”, but that’s inflammatory and not entirely accurate, so I couldn’t do that.

I could just as easily have titled this blog “Stubborn Axys Users Refuse to Embrace Benefits of ACD Interface” or “Axys Users Slow to Hire Consultants to Address Schwab Point-to-Point Interface Changes”, but in truth Schwab is discontinuing their support for Axys in the data they provide directly to their customers via the Schwab download, so I had to go with “Schwab Discontinuing Support of Axys Point-to-Point Interface – Again?”  Besides, picking one of those other titles would have made me write a blog with a different message.  In advance, I’d like to clarify that this issue only impacts the Schwab point-to-point interface and has no effect on those that receive their Charles Schwab data from Advent’s ACD interface. 

I need to apologize to those who have read my blog regularly in the past.  First, I am sorry I haven’t posted anything in a while.  Additionally, I must apologize that this blog may not seem particularly newsworthy for some.  You may even be thinking, Didn’t this happen eons ago.  The answer is yes and no.

About twenty years ago, there was some drama about the point-to-point interface that Charles Schwab provided to its customers and Advent, being Advent, may have been perceived as attempting to screw Charles Schwab and its customers to make more money.  Schwab, being Schwab, sued Advent – to paraphrase the judge told Advent, “You can’t do that.”

According to what I can dig up now, the firms quit wasting each other’s time and money nearly seven months after that preliminary injunction, coming to a compromise that allowed Schwab to continue to provide their point-to-point data for a period of time.  In my recollection of the events, it seemed much more drawn out.  Fast forward twenty years, and now everyone that is still relying on this particular set of data directly from Schwab’s download is back to square one.

Back in 2002, the underlying issue was that Advent didn’t want Schwab to continue providing the data without going through ACD and Schwab wanted to continue providing the data to satisfy their existing customers, who had grown dependent on getting that data via the point-to-point interface.  From the perspective of those Axys customers, it is easy to understand their position then and now…  it is pretty much free, and it works.  Why would we want to change that?

Somehow, for more years than I would have thought possible these holdouts that either saw no reason to fix something that wasn’t broken or were too cheap to move to ACD continued to do what they had been doing for decades.  I never thought this would have gone on as long as it did.  Alas, as they say, all good things must come to an end.  That is apparently what is happening now.

Schwab is in the process of stopping production of the files that feed Dataport for this subset of Axys users.  Last month, they stopped producing the price (CSMMDDYY.pri) files; they are also planning to stop producing other key files, such as transactions, sometime in 2023.  The sudden inability to create a price file no doubt caused some difficulties for those still dependent on them.  As a result, a couple firms reached out to me.

After a brief discussion with the first firm, I agreed to automate the creation of the missing price file.  According to my customers, both Advent and Schwab were unwilling to assist them with the issue.  Advent’s not planning to make changes to their interface to take in the new Schwab files, and Schwab’s not planning to help clients transform the files into something that can be ingested directly into Dataport.

It sounded way too easy for someone with my experience, and I thought it would only take a “few” minutes.  Somewhat embarrassingly, I spent a few hours creating the automation necessary to do the translation.  However, in a subsequent implementation for another customer, I was able to have a meet-and-greet call with them and a follow-up call to implement and test the solution in their environment very quickly.  All of it was accomplished in a couple hours, and on the very same day the prospective customer contacted me, leading me to believe that future implementation may be performed in a matter of minutes.

Those dealing with what is currently limited to a pricing issue have a handful of choices, none of which are fun to deal with when you need yesterday’s prices now:

  1. The most obvious choice: consider implementing the Schwab Interface via ACD.  It might be worth it.  I am not kidding.  I have plenty of clients that use ACD.
  2. Use a third-party pricing service like IDC/ICE or Telemet.
  3. Key the prices in manually.  I am not recommending this, but it is certainly an option.
  4. Utilize automation to recreate the missing price file (CSMMDDYY.pri) from the security file (CRSYYYYMMDD.SEC) now provided by Schwab.  This isn’t very difficult, and that is what I have done for those who have asked me to resolve the issue for them.

Addressing the pricing issue alone is a stop-gap solution at best.  The larger issue down the road is translating the transaction files, which will need to be done in 2023.  At my clients’ request, I have agreed to look into doing this for them as well, and I will most likely do it.  With my experience building Axys interfaces and doing the requisite transaction mapping et cetera it probably won’t be that big a deal, but it will certainly be more complicated and time-consuming than the Price File Translator was to create.

As always, if this issue is something your firm needs assistance with, please feel free to contact me directly.

I like to think that the greater purpose of much of the work I do with investment professionals is to simply show them what is possible. If you understand what can be done and how, I trust that you will have no problem coming up with many things that you want to do. Process automation, workflow improvements, integration, custom apps, and enhanced reporting are all easier to imagine and implement in your own environment when you have the benefit of the insights and perspective of relevant and significant user experience.

Like many before it, this article was written with that idea in mind. There is a very practical component (the source code below) which a small number of users may be able to take advantage of; the larger audience of managers, investment operations and technology professionals will hopefully come away with the idea of what can be done and roughly how it can be done, without necessarily planning to do this particular thing. More likely, readers will file away the knowledge of this article and revisit it later.

Most readers of this blog will not read it on the day I post it, or any time soon. Some day in the future, when the information in this particular blog becomes relevant to them, they will run a search and eventually find this article.

Audit Trail Usage

The Audit Trail (didpost.aud) file, a critical component of Advent APX and Axys, empowers users to review any transactions posted to portfolios in the system.  It can also facilitate small- and large-scale removal of transactions that are posted in error. Among some Advent users, proactive management of the audit file is almost nonexistent until they hit the wall by letting the file grow to an unmanageable size or find it useful and perhaps even necessary to create subsets of the file as part of an audit.

One approach to proactively managing the file in Axys is to have a routine process whereby the file is copied quarterly or monthly and the current file is deleted.  In this scenario, new transactions posted create a new Audit Trail file.  And if you need to reference older transactions, you can temporarily copy the current file to another file and restore the file you need to access as the didpost.aud.  When you are done accessing the old data, you revert things back by copying the original Audit Trail back to didpost.aud. Though the process is a bit clunky, somewhat risky, and manual, there are probably many firms using this approach.  You could easily automate the processes I have described to create a more elegant solution.

In the past, I created some automation to routinely export the audit trail to a CSV file and create separate audit files of those exported CSVs for pre-selected periods.  The code to do this is not complex, so I doubt I am the only one who has implemented this approach.  This worked fine for many years, but it stopped working at some point.  I am not sure when it happened, but I found that the ability to export the audit trail file in Axys 3.x via IMEX no longer worked reliably.  Any attempt to export the Audit Trail would abend, leaving you with only part of the exported file you needed.  Initially, I wasn’t sure whether the issue was limited to one of my customers, but after reviewing a few sites I work with, I found that the ability to export large audit trail files using IMEX no longer worked across the board. The issue is an Axys issue and not necessarily an APX issue, but I haven’t tried to export the audit trail in APX recently.

This failure to export Audit Trails posed quite a problem.  Though the Audit Trail could be reviewed, and copy functions within the review windows worked, the size of the files made any kind of manual selection process onerous and prone to error.  Besides, what would you do if you did select the data?  I guess you could copy it into an empty trade blotter and save the blotter to a different file, but the trade blotter isn’t an Audit Trail file.

My assumption was that the integrity of the Audit Trail file was intact, but the function to export a larger file was broken.  Usually, I frown upon working with Advent files directly.  I prefer to work with exported files and consider that a best practice to avoid issues that can occur when the format of Advent files ultimately changes in later versions.  In this particular instance, I was forced to read and write AUD files directly since the export mechanism wasn’t working properly, but I was happy with the end result and thought the source code might be useful to others.

Source Code to Fix Axys Audit Trail Export Issues

The code below reads the Audit Trail (didpost.aud) file in its native format, creates a time-stamped backup of the original file, and creates an annual didpost file for each year in a backup folder within the f:\axys3\aud folder.  As some of you consider using this code, you may be concerned. After all, the integrity of the Audit Trail is not really something you want to mess around with lightly. You may even be thinking, Just because you can doesn’t mean you should. Nevertheless, I created, carefully tested, and successfully implemented the code to fix the audit trail for some Axys users that realized they had this issue.

Everyone has a different level of interest in the tech end of things. Some people want to understand it completely; others don’t want to know anything about it. I suspect that most of my readers fit somewhere in between those two extremes. On any given day, depending on what else is on your plate, you may lean towards one end or the other. In some cases, it simply makes more sense just to have someone like me take care of these things. If you have a problem with your Audit Trail that needs to be resolved, it may be one of those things.
