main() runs once per bar?

[kztd]

I must be missing something, I read that main() executes once per bar when its loading, but when i put code in there, it only executes once.

function main() {

Alert.addToList(getSymbol(), "Once per bar??", Color.blue, Color.white); // <-- I only get one Alert

return 100; // <-- But this does plot for every period

}

main() executes once per bar when it is loading. The reason you get only one alert is because the Alert.xxx functions execute only on bar index 0 (or bar index -1 if setComputeOnClose() is used)
