Hey all,

Just trying to create a script that triggers a trade based on parabolic sar

here is the code.

 

Code

input accFactor = 0.02; input accelerationLimit = 0.2; def sar = ParabolicSAR(accelerationFactor=accFactor,accelerationLimit=accelerationLimit);

The scripting editor highlights ParabolicSar and throws an error saying

No such function: ParabolicSAR at 5:12

It works fine when I do this for other studies, having trouble understanding why I get this error with the PSAR study

It seems the ParabolicSAR is a study and not a function in thinkscript. Refer to TOS Learning Center for more info.

Have you tried creating a new study by copy & pasting the script from the ParabolicSAR onto the new study then create buy conditions and add whatever alerts you want in the new study?

Yes, I realized the issue is TOS doesn't support studies that use recursive caclulations (like ParabolicSar) so this is unusable for triggers or alerts
