My EA works perfectly on 500:1 margin leverage.

i would like to amend the support for bigger margin leverage.

Any code advise to get the exact relationships for lotsize calculations on higher than 500 ?

for example:

double TotalLotsToAllocate = m_PositionForInstrument.TotalLotsForAllPositions = dLotsSizeToPlace * MarginLeverageValue();
Leverage has been misunderstood.

Leverage is a factor between volume and margin requirements.

All it tells is how much volume your account balance can support.

The whole code, wherever you got it from shows, you do not want to use any of the code from that source.

Whoever wrote it has fundamentally misunderstood money management and margin requirements.

Also, leverage has nothing to do with lot/mini lot/microlot accounts.

Even if there were a correlation. A higher leverage and a Microaccount simply do not make sense.


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 You place the stop where it needs to be — where the reason for the trade is no longer valid.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