Forex trading 2019 TA/FA setups and discussion, page-121

Hi TwoHands

Yes, this is the reason Many Manual traders lose money, they are thinking in two short a time span.  There strategy may be a good strategy but 2 - 5 losses and they give up.  If they had back tested the system, they may have known there strategy would do this for months before producing a great profitable run.  It is the reason the Algo trading has the advantage because losing periods have been accounted for with the knowledge of possible draw downs that may occur if the future market matches the previous markets history.

Then I ran some real quick optimized tests through the EA Analyser of 12 charts and it produce results -
2015 return 68%
2016 return 39%
2017 return 92%
I reckon some traders would have dumped the EA in 2016 because the result wasn't as good.  He would have missed out on a great result last year if he had.
