But you can basically program any rules you want, such as yours. It would however involves sigscalein and sigscaleout as though. But once you understand loop programming, then it shouldnt be a huge problem, just a nice challenge.

Many thanks Paul,
you are very generous and your code indeed matches Buy and Sell as needed.
Also, your suggestion above regarding multiple trades on the same bar does allow to calculate the total P&L of the test, but the total number of trades (and all statistics calculated on them) will be wrong.
But nevertheless, your code is a very nice departure after all this chatting.
Greetings,
Angelo.
