When main() is called by eSignal

[dancclark]

Does anyone know what the basic sequence is when eSignal is running an EFS script in real time . By that I mean, does the main() function in an efs script get called multiple times per bar or only once per bar ?

I ask because I created an indicator, but sometimes it gives a false signal during say a 15 min bar. I assume eSignal is calling main() multiple times per bar.

If thats the case, is it true to say that the only sure way to base a trade decision on an indicator chart value is after the bar is over and the next bar has started ?

main() is called once per bar on historical bars as the formula is loading and then once on every trade on the current bar assuming you did not use a setComputeOnClose() statement in preMain() or did not enable the global compute on close (see also section 1.4 of the Beginner Tutorial 1 - EFS Basic and Tools)

Thanks. I have my efs draw a line on the screen if a certain numeric level is reached, but if I'm watching the chart in real-time on a 15 min chart, I see the line drawn sometimes, and then it disappears. If main() is called once, I guess that would imply that the code within main() is being constantly run while the current '0' bar is open ?

What else could explain the behavior I described unless the code was being continuously run , since I have something just like this in my main() in the EFS code:

if (value >= x) drawLineRelative(...
