MQL：資金管理語句塊

以可承受損失資產百分比計算倉位大小：

extern double EquityPercent = 2
extern double StopLoss = 50
#計算風險資金額
double RiskAmount = AccountEquity()*(EquityPercent/100)
#計算指訂貨幣的每點價值
double TickValue = MarketInfo(Symbol(),MODE_TICKVALUE);
if(Point == 0.001//Point == 0.00001) TickValue *= 10;
#計算倉位大小
double myLots = (RiskAmount/StopLoss)/TickValue
