Looks like we're turning this thread into a discussion about backtesting EMA strategies, finding the optimal parameters, etc. If this is starting to become too tangential to your original idea of this thread, i.e. you think we're hijacking your thread, let us know.
No worries, thank you for asking. Been much to busy to post lately, and the discussion is certainly on-topic, so I'm fine with it.
