modify order comment

New comment
 

I'm new to programming mql4. can you change trade comment when ordersend is rejected (ERR_NOT_ENOUGH_MONEY)?

I send this order int OrderSent(symbol,OP_BUYSTOP,1,price,3,stoploss,takeprofit,"recoverBuy",magic,0,clrBlue);

if so, how do I change trade comment?

 
  1. Why did you post your MT4 question in the Root / MT5 EA section instead of the MQL4 section, (bottom of the Root page?)

    Next time post in the correct place. The moderators will likely move this thread there soon.

  2. Only the broker can change comments.

  3. You shouldn't be trading such a huge percentage of your account. Risk depends on your initial stop loss, lot size, and the value of the pair.
    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 You place the stop where it needs to be - where the reason for the trade is no longer valid.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. Account Balance * 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 (EUR, in this case).
                MODE_TICKVALUE is not reliable on non-fx instruments with many brokers.
    4. You must normalize lots properly and check against min and max.
    5. You must also check FreeMargin to avoid stop out
    Most pairs are worth about $10 per PIP. A $5 risk with a (very small) 5 PIP SL is $5/$10/5=0.1 Lots maximum.
