EA update

New comment
 
my MQL5 code actually sets stop loss and targets the update I want to make is the EA is it should count quantity based on entry point and stop loss so that it losses only 2 dollors per losing trade.....can anyone help me with it 
 
RajPatil_007:

In summary you should do this:

Balance - Equity = Profit/Loss

If Profit/Loss >= -2 = Close trades

Code it and show your attempts.

 

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 You place the stop where it needs to be — where the reason for the trade is no longer valid.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.

How to calculate take profit from currency

Fernando Carreiro, 2022.09.05 17:00

These are all the same equation written in different ways ...

[Volume]      = [Money Value] * [Tick Size] / ( [Tick Value] * [Stop Size] )
[Stop Size]   = [Money Value] * [Tick Size] / ( [Tick Value] * [Volume]    )
[Money Value] = [Volume]      * [Stop Size] * [Tick Value]   / [Tick Size]

[Volume] in lots
[Stop Size] in quote price change
[Money Value] in account currency
