Accuracy of backtesting.

  1. I do backtesting and get very favourable results. I then insert exact same values in trading system and when I backtest before activating automatic trading I get completely different results. Why?
  2. I do backtesting and one of the variables is “FLAT AFTER HHMMSS” which is supposed to exit all trades at time specified in HHMMSS.  The results for a certain set of variables are exactly the same even when the exit time is for example  140000, 150000 or 160000 on a 10 min chart, which is obviously incorrect.

  Any ideas will be appreciated.

  It’s hard to say anything about it like this. Do you have more information?
  Code (part?), backtest reports from before and after?
