I also tried to test/run this code. Got the same error code? Tried to // the zero but then got the failure code in probacktest. then i tried to return zero, but same failure code.

Not before i downloaded @Grahal `s version than i got it to work. What did you do with the code to get it to work? will try to run the new version whit trailing stop now to see if i can get that to work.
