ThinkorSwim "custom expression subscription limit exceeded"

[wildeye]

Hi, I'm running across the custom expression script limit when scanning using the code below. I'm wondering if anyone has any suggestions to lean out this code while preserving the same function so that i can have hit more searches with it. I'm capped at 200 with this code atm. Thanks!

def A = hl2;
def highestvolofday  = highestall(if GetLastDay() == GetDay() and highestall(volume) then (volume) else double.nan);
def High_vol_Price =  if  volume == highestvolofday then A else High_vol_Price[1];
Plot scan = (High_vol_Price*100) * highestvolofday;

@wildeye It isn't your code that is at fault... It has to do with the sheer number of Custom Watchlist Column cells being populated across your entire Thinkorswim install... That limit is between 1100 and 1500 calculated cells... Reducing the number of Custom Watchlist Columns OR reducing the number of symbols in the watchlists, scans, etc, is the only solution...

One thing I noticed today while trying to work around this is that if you sort the scanner by the custom column using the dropdowns next to the scan button, it will correctly sort the exceeded ones. So you can get an idea of what the number is by seeing what is above it and below it. This does not work though if you simply click on the column header.

The following solved it for me -
I had detached watchlists. I simply closed all detached watchlists and reopened only one.

Not certain if this is discussed anywhere else as the search I ran did not reveal any other conversation on this topic.

The way to run as many "expressions" as you want is to install multiple instances of the Thinkorswim platform and run them simultaneously.

In my setup I have one instance dedicated to charts alone while 4 or 5 others are running unique versions of custom watchlists with multiple custom columns.

Of course you will adjust the number of columns by the size of watchlist or scan you are working on.

Simply download Thinkorswim as many times as you wish (alter the name for each on installation). Set the memory accordingly for each install and you are good to go. I simply rename each shortcut on my desktop to remind me which watchlist (or lists) that instance contains.

I forgot to mention that the user will be limited by the amount of memory installed on their computer. But even lower memory levels should still allow multiple installs.

My friend, this is the most awesome thing Ive read all week.

This has been a problem of mine for years. Now with joining UTS and adding lots of complex watchlist items is a major problem TOS support has no good answer. It related to the total number of whitelist calculations active at one time. It may be mitigated by having only one watchlist with your calculations in and the rest only have basic date, symbol and notes.

I also ran into this and thanks to the posts here (the questions and the answers are equally informative and helpful!) I realized that a second instance of thinkorswim running on another computer was my culprit. For a variety of reasons, I sometime run it on a separate computer where I create custom Excel calculators for myself using RTD (real time data) and having them both running put me over the limit. Now that I know that, as long as I don't need those custom columns at the time, it's no problem and when I'm working on my actual trading, I can just shut TOS off on my other one. Thanks to ALL the great participants on this site!

Can anyone tell me what the verbiage "custom expression subscription limit exceeded" means in the label columns of my TTM Squeeze dashboard where it is supposed to be displaying the squeeze status and histogram information?

 

[rad14733]

@markallenwilson1016 - That means that you either have too many Custom Watchlist Columns on your Watchlist OR too many rows in the Watchlist x CWC's... TOS can only utilize ~1500 "custom expressions" in total for each instance of TOS running... To avoid this error either use less Custom Watchlist Columns (Custom Quotes) or limit the number of rows in your Watchlist tables...

Hi @MerryDay Is below search result normal? I see for couple of stocks, custom watchlist columns are showing custom expression subscription limit exceeded ?
