Signals randomly skipped

If you are trading with real-time data, it can only happen because of problem with AFL. See videos below how to check AFL issues. You can cross-verify by using sample AFL in Amibroker Jump Start.

If you are using bar-replay, and you still face issue with sample AFL, then probably the data provided by your data vendor is corrupt. During careful bar-replay, you will find that signal comes on second-last bar instead of last bar. To solve this issue

In Amibroker go to Tools->Preferences->Intraday and make sure to tick START time of interval.
In bar-replay, put step-interval to minimum possible. Example: using 1-minute step interval with chart time frame of 5-minute.
In AFL parameters, use Candle Completion instead of Immediate.
