Hi Ed,
Thanks for your message, it was really helpful.
You said "However I can advise to avoid the situation completely.
Because what good is such a backtest if you can not really be certain
that you simulate reality?"
This is so true. It does not matter if the assumption is mine or of
Amibroker, it would be an assumption not reality. But How to avoid
this situation the only way I can see is to use Amibroker
professional version with tick data. Can you think of any other way
out?
Best regards
Rizwan

the stoploss before the profit stop. However, you could write your
own ApplyStop routine using AFL where you use for, if, else etc
statements. Then you can tell exactly what you want the priority to
be.
