if(LotSize < MarketInfo(Symbol(),MODE_MAXLOT)) LotSize = MarketInfo(Symbol(),MODE_MINLOT);
LotSize will always be less than (or equal) to MAXLOT at this point. -
Never risk more than a small percentage of your
account, certainly less than 2% per trade, 6% total to the account. Risk depends on your initial
stop loss, lot size, and the value of the pair. It does not depend on margin and leverage. No SL means you have infinite
risk.
- You place the stop where it needs to be — where the reason for the trade is no longer valid.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.
- 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.)
- 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.
MODE_TICKVALUE is not reliable on non-fx instruments with many brokers - MQL4 programming forum 2017.10.10

Lot value calculation off by a factor of 100 - MQL5 programming forum 2019.07.19 - You must normalize lots properly and check against min and max.
- 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 or 0.1 Lots maximum.
