Hi Miroslav,

I've been watching your video series on Youtube and how to create EURUSD, GBPUSD, USDJPY strategies.
In Part 11 (https://www.youtube.com/watch?v=o5ms2bbkVQU), you show the creation of a GBPUSD M15 strategy based on Keltner Channels, Bears Power, and NoNo indicator (the strategy adds and close).
I've created it, and on my GBPUSD M15 FXCM data, it reaches margin call right away. See attached screen cap.
It has nothing in common with the nice equity curve you have in your video.

I was wondering what I'm doing wrong (all parameters are exactly the same), or is it an example of overoptimized strategy (curve fitting) --> when using FXCM data (whereas you used ActivTrades data), the result falls apart.

Thanks, your answer will help me understand better and learn from your experience. Also, it will help me understand how not to make an overoptimized strategy and just wipe out my account...
