Hi Ed,
Thanks for answering. Yes, I have to rethink the exit since I am simulating a trail stop but I need it more complicated than the one I can implement with Applystop().
Regarding the problem with Buystop I have found a way to fix it. I need to place the Buyprice sentence:
BuyPrice=ValueWhen(Buy,Max(O,Ref(Entrypt,-1)));
below the Exrem() sentence, thus I remove the other ocurrences of Buy that move the Buyprice. Try it and you will see that the Buyprice is now a constant while long (the blue line). I guess this is a typical error when coding since we always want Buyprice below Buy signal. Buyprice needs to be static.
regards,
Oscar
