so its a problem with bad data in strategy tester.

but this also happens on demo accounts... same error ...sometimes works, sometimes doesn't.... how can i test, where can i test the ea on demo?

as is my first ea i'm still not sure if i have the right code :)

i keep reading the posts, and this happens on test generator...

can the same problem appear on demo ?

what about real account ?
