One trade per condition meet

[kaluiyke6]

Please I need some help.
I coded a robot for mt5 but it takes more than one trade per signal. It opens another trade after taking profit of the first trade. How can I stop it from taking another trade after the first one?

If within 1 candle once per bar, if not use a flag to allow/disallow trading, just make sure it gets reset
