DislikedThe opening of a candle happens at the same time as the close of the previous candle. So in this case, those 2 cases are considered the same.
alert.onbarclose=false should make the alerts fire once/bar when the condition is first triggered. However, the trigger condition may reverse before the candle closes. I'll have to perform some tests to see if/why it is not being triggered.Ignored
I just tested it again, just to be sure and it doesn't trigger the alert. I have been testing on 15m charts where the TF are 30m, 1h, 4h. After testing over 6 months (on 2 pairs for now..) I haven't really had so many reversals that would give me a fake signal.
