Hi ,
I am having diffuculties to calculate rigth order size for live trading with Oanda. Leverage in the account is set for 30 for the asset. Basically an Apha triger to place a market order while having no open position for full available margin in the account , and after when position profits ie there is available margin to trade, trying to place a new market order with avaialble margin for pyramiding. Calculating postion size by simply available margin / asset price and multiplying with leverage worked very well in back tests however in live trading it always calculate much bigger size than tradable.

Instead of manually calculating the order size, there are two methods that can assist in margin modeling. GetMaximumOrderQuantityForTargetValue(portfolio, security, decimal) will return the maximum market order quantity to obtain a position with a given value in account currency and GetBuyingPower(portfolio, security, direction) returns the buying power available for a trade. These built-in methods should provide you with more accurate results.
