Hi

Need to know why My Order (TP) was Not Executed as Price has gone below my Set Target i.e. 0.99600 where as Price gone to 0.99517 on EURUSD.

Also, note that Bear Candle Wick is Crossing my TP Line as shown below in attached Snap.

Your order was placed 2022.08.12 but you are looking at the price chart for 2022.07.14 which is one month earlier than your order.

That symbol is not an "i", it is a a vertical bar or pipe "|".

A single bar "|" has the meaning of a Bitwise OR Operation, while a double bar "||" has the meaning of a Logical OR Operation.

By the way, you may find it helpful to learn C or C++ as well because MQL is based on it and there are many more source of educational information out there for C/C++ than there are for MQL.

  2. GetLotSize doesn't compute correctly.

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 You place the stop where it needs to be — where the reason for the trade is no longer valid.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

You can only trade what your account offers. So choose a broker and a type of account that offers the symbols you want to trade.
