postmain, How to tell if exit or just switching time?

[windswepttom]

Hi,
When using the postmain, how do you tell if you are exiting eSignal or switching stocks or switching time frames?

Thanks
Tom

Hello Tom,

Try adding the following code to a test formula and it will alert you as to when postMain() gets called.

function postMain() {
    Alert.playSound("train.wav");
    debugPrintln("interval was: " + getInterval());    
    debugPrintln("symbol was: " + getSymbol());
    debugPrintln("postMain executed!.");
    debugPrintln("  ");
}

Thank you Jason,

I about had a heart attack, I had the volumn turned up when the "train.wav" sound played. lol

It only tells me what the current symbol is and not what the next one is and not if I'm exiting eSignal. I can set a global variable and then tell if I changed symbols on entery. I think that will work.

Tom, you're most welcome. Glad to hear you didn't miss the train.

The postMain() function can't be used to tell you what the next symbol or interval is. This function is the last thing executed by the formula before it get reinitialized for the new symbol or interval. Upon exiting or shutting down eSignal you should hear the audible alert however.
