Hello,
I am running a study that runs every bar closes (like every study).
In this case, the study needs to wait few seconds, before execution, because it has to get some data from an external text file.

The Reading from the file is working, but if i am using the C++ Sleep() function, the whole chart is stuck!!.

I have other studies that must run just after bar is closing.

Q:

1. what is the best way for doing that?
2. C++ Thread is having a compelation error for me. Is it?
3. Is where is a configurablility way, to tell a study to run only after other study finished?, or after "X" seconds (through the Study Settings)?

Hope to hear from you soon,
Thanks, Ariel

AC94882 - the following parameters are likely to help in your case.

in sc.SetDefaults section:
sc.CalculationPrecedence = STD_PREC_LEVEL; -- For master study
sc.CalculationPrecedence = LOW_PREC_LEVEL; -- For Slave study

Support, Thanks!
Do you have a way to postponed the study from running, in few seconds (variable), and not stop the whole chart updates?

So the chart will be updated by the rest of the studies, and a specific study will be executed after a while...

This is our answer:


We recommend setting your study to update always:

This way, your study is continuously called and can take the necessary action at any time without having to rely on new market data.

For any study that needs to be calculated after other studies, set them to have a low calculation Precedence:
