  Hi All

  I am Alfred, a new beginner in this

  I have run a auto system, the backtest (right side) is  2 bar, but actual run is 3 bar. and the profit is much difference!

  Anyone can explain this…

  Many thanks!

  Entry and Exit times are different also.

  • Backtest has fixed spread and no slippage
  • Live running (called Forward Test) has variable spread and slippage and variable minimum distance for stop losses settings.

  It’s a wonder anybody makes any money at all? 🙂 Hey 90% of us don’t! 🙁

  Mmm … I wish it were that simple!

  Only way you will know is to run BT and FT over the same period for  > 50 trades, maybe more?

  Do the trial and let us know please?
