ThinkorSwim App System Lag

[MerryDay]

Good Afternoon Traders! I've read a lot of posts around the web about how to speed up TOS but still looking for some answers.

Four main questions:
1) Does referencing built-in TOS studies in User Defined studies slow things down? (I reference SequenceCounter in one of my studies)

referencing several complex studies whether built-in or custom could potentially slow down charting.
Sequence Counter on its own, will not.

2) Does the AddCloud function slow things down? (I have a study that plots several different clouds simultaneously)

AddCloud is not a complex function, in of itself should not slow charting down

3) I have a study that is about 1500 lines long. It has references to TOS built-ins, uses several instances of ATR, EMA, Fibs, etc. It seems to really bog down TOS. Does anyone know if I separated out some of the sections into individual studies and then stacked them on a chart if that would improve performance?

The number of lines of code has no correlation to whether a script is complex.
Four lines of code with complex functions could be too complex.
2000 lines of simple plotting might be fine.

(I've heard TOS is a single-core/thread application so I'm guessing this won't help because there's still only one core doing the same amount of work...)

You are correct.

4) Does anyone know how to reference a TOS built-in study but also have that reference address a higher time-frame? In other words, if I wanted to see SequenceCounter values from a 15Min time frame but have them plotted on a 5Min chart is that possible?

Sequence Counter is a proprietary code. No modifications can be made to it.

Some traders run multiple instances of TOS on their systems - that's not going to help me if I want mostly everything on a single chart.
However, I have been running multiple instances lately and have allocated a minimum of 24GB of RAM to each instance. Can't quite tell if that's helping.

Here is a thread for the discussion of ram:

I have been experiencing significant lag in Thinkorswim lately...Anyone else encountering the same issue?

I came across the following advice posted in Reddit and it has helped:

Hope this helps...

Good Luck and Good Trading

I do most all of these daily and perform the Collect Garbage multiple times throughout the day...

There are several posts on this subject by MOBIUS, without a double the master of all things thinkorswim, and he states that users should set the memory allocations to the MINIMUM, yes, the minimum. He uses like 56/1420 or something very small. His Logic can be found in the reddit thinkorswim sub. I keep mine small on three different laptops, no lag, no clearing garbage, Lightning fast with many charts and custom indicator running. Hope this help.

“delete the /usergui file” Hmmm. I'm intrigued but concerned. What is being deleted in the /usergui and how does that speed things up? I wonder if that applies to both Macs and Windows machines.

Deleting the usergui clears out temporary files which are no longer needed and forces the application to return to some system defaults... We should be less concerned about what exactly is taking place and just be happy with improved performance... Deleting usergui is one of the first goto's whenever you are having any performance issues within Thinkorswim... Several years back doing so was part of my daily restart procedure, before one of the past major releases fixed a few ongoing performance issues... Just delete it and don't even think twice about it...
