are backtests really realiable or are they only there to check if the EA works?
so have you personally made the experience with your EAs that they work or do not work in the backtest BUT then do not work or do work in reality on the live market?
Thanks for sharing your experience.
It depends on how big the average trade is in pips.
If it is a scalper and it relies on just a few pips per trade then it is very likely to suffer from slippage and variable spread issues on real accounts.
However if the EA uses larger trades, say 20-50+ pips then the backtest results are likely to be much more reliable.
Sadly the backtester does not report average trade size in pips, so you have to do some investigation to find out the average trade size in pips
So if I understand right: The backtest is more reliable for long term strategies on higher time frames like H4 and above?
For small time frames and micro operating EAs useless?
