Why profit is not correct on mt4 backtest!

New comment
 

Why the profit on attachment picture is not correct on back testing?  Please help me. 

It must be  100*0.2lot*(1850.627-1841.673) = 179.08$

Thank you,

 

Please don't post randomly in any section. MQL4 and MetaTrader 4, has it's own section on the forum. I have moved your topic to the correct section.

No image is placed (because your rating is still too low).

So instead, use the "+ Attach" button in the lower-left corner of your posting text box, to attach your image file.

  1. Total Profit is OrderProfit() + OrderSwap() + OrderCommission(). Some brokers don't use the Commission/Swap fields. Instead, they add balance entries. (Maybe related to Government required accounting/tax laws.)

  2. Risk depends on your initial stop loss, lot size, and the value of the symbol. It does not depend on margin and leverage. No SL means you have infinite risk (on leveraged symbols). Never risk more than a small percentage of your trading funds, certainly less than 2% per trade, 6% total.

    1. You place the stop where it needs to be — where the reason for the trade is no longer valid. E.g. trading a support bounce, the stop goes below the support.

    2. AccountBalance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot) (Note OOP-OSL includes the spread, and DeltaPerLot is usually around $10/PIP, but it takes account of the exchange rates of the pair vs. your account currency.)

    3. Do NOT use TickValue by itself - DeltaPerLot and verify that MODE_TICKVALUE is returning a value in your deposit currency, as promised by the documentation, or whether it is returning a value in the instrument's base currency.

    4. You must normalize lots properly and check against min and max.

    5. You must also check Free Margin to avoid stop out

    6. For MT5, see 'Money Fixed Risk' - MQL5 Code Base (2017)

    Most pairs are worth about $10 per PIP. A $5 risk with a (very small) 5 PIP SL is $5/$10/5 or 0.1 Lots maximum.

 
Here is my attached pcture.

Thank you very much! I think because of swap...

I've asked Exness to set swap to zero on back testing and they said they can not. Can we set swap to zero on MT4 when back testing?

Yes, by editing the FXT files with 3rd party tools (e.g. TickStory or Tick Data Suite)

However, discussing 3rd party tools is not allowed on the forum, so you will have to do your own research.
