Not exactly the answer but relevant:

Volume must be rounded to a suitable amount for trades. Check out Symbol.NormalizeVolume in the reference.

RE:

This will give you a calculation to manipulate volume with whole numbers...

var smartVolume = Volume * (int)(Account.Equity / openingBalance)

Hello,

I'm trying to make a cBot that enters positions at with a certain percentage of the account balance at risk.

For example, if I wanted to risk 2.5% of account balance per trade and I've worked out I need a stop loss of 60 pips for the current trade, how would I calculate the position size taking account base currency, the symbol being traded and the pip value etc?

I have all the variables I need to place a limit order except volume... this is what I'm trying to calculate.

// This is where I've got to but it's clearly not right.
var volume = (Account.Balance * RiskPercentage / 100) / (stopLossPips * Symbol.PipValue);

TradeResult result = PlaceLimitOrder( TradeType.Buy, Symbol, volume, entryPrice, label, stopLossPips, takeProfitPips);

Any help would be greatly appreciated.
