New comment
 

Hi,

I just backtesting my EA and I saw an abnormal behavior in the graph shown below,

After looking into the chart there isn't any particular trade that resulting in that drawdown. I looked into the journal log and found that after 2022.06.30 the strategy tester restart the equity of the strategy tester.

Does anyone ever experience this issue? and if there's a solution to this problem?

I would say stop loss hit. And you get a drawdown. (Buy order could be stop loss of a sell order.)

If you use Grids or Martingale, sooner or later you will be hit by large drops in your account and eventually blow it completely.

The Strategy Tester is showing you that and warning you. Instead of understanding that, you are choosing to believe that the tester is wrong, which it is not.

Thanks for the remainder but just like I said above this issue happened at 2022.07.01 and before this date there's no open position. I understand if the problem is loss because of loss in position but this is not, strategy tester just revert the equity and start again at initial equity.
 

Disable forward testing.

Also do not use profit in pips. It is useless for - martingale / hedge / recovery / always never lose - strategies because it does not take into accounbt margin requirements.

Thank you the problem is resolved, but could you elaborate me more about using margin requirements for profit taking in those type of strategy?

 

Regarding margin requirements, please google, i am not going to repeat it here.

The profit in pips mode is suitable to check the profitability of the bare bone strategy without money management only. It does not take into account if you trade 0.01 lots or 10 lots, just the difference in the open and close price of a trade.
