MT5 BackTest 99% Or Tick Data Suite MT4 99.99%

 

Hello everyone.

I have EA on MT4 and backtest with Tick Data Suite, it has very nice result. Today I convert my EA to MT5 and backtest with everytick, it is different. So doese anyone has experience with this problem? Which one should I believe?

  1. The 99% of TickDatasSuite is set not calculated, so it means nothing.
  2. Mt4 and Mt5 handle various things (spread, crossrates, ...) differently so the results must be different.
  3. Mt5 gives you more options to check unfavourable market scenarios - use this and do not stick to the best result.
  4. The (optimized) test can only be the first step, try your EA immediately on demo accounts with various symbols (if it would make sense) - always look for the worst result as this can break your (financial) neck.
