A_GetPosition获取当前持仓总是失败

老师好，我获取持仓或订单委托量总是返回0，就算账户有持仓依然返回0，可以帮忙看下哪里出问题了吗？================Position pos; Bool ret = A_GetPosition(pos, "", 0); Integer openOrderCount = A_GetOpenOrderCount(0); Numeric BuyFlagNum = 0; if (BuyFlag > 0 and BuyPrice > 0 and pos.longCurrentVolume == 0 and Close == BuyPrice and openOrderCount==0) { //Buy(0,BuyPrice); // 入场 做多 Array<Integer> orders; Bool ret = A_Buy(MainSymbol,1,BuyPrice,orders); Print("A_Buy:" + IIFString(ret, "True", "False") + "," + TextArray(orders)); if(ret) { sendCount = sendCount + 1; } }
