主力资金净流副图指标，本指标用来计算主力资金净流入
{计算主力资金净流入}{LARGEINTRDVOL逐笔买入大单成交量}{LARGEOUTTRDVOL}大单买入金额 := AMOUNT * (BUYVOL / VOL);大单卖出金额 := AMOUNT * (SELLVOL / VOL);{中单买入金额 := AMOUNT * ((TRANSACTVOL(0,2) - BUYVOL) / VOL);}{中单卖出金额 := AMOUNT * ((TRANSACTVOL(0,3) - SELLVOL) / VOL);}{主力资金净流入:(大单买入金额 + 中单买入金额 - 大单卖出金额 - 中单卖出金额)/10000,NODRAW;}主力资金净流入:=(LARGEINTRDVOL-LARGEOUTTRDVOL)*C;
{计算成交量放大倍数}成交量放大倍数:VOL / MA(VOL,5),NODRAW;
{MACD指标}DIF := EMA(CLOSE,12) - EMA(CLOSE,26);DEA := EMA(DIF,9);MACD := (DIF - DEA) * 2;
