相同手数平仓反向几次后比如三次，就平仓出场该怎么写

input: lot(5), num(3);  //lot是手数，num是平仓反向的次数

var: mp(0), flag(num);
mp=marketposition;

if mp[1]*mp=-1 then
        flag=flag-1
else if mp[1]=0 and mp<>0 then
        flag=num;
{这段是平仓反向的次数统计；平仓反向一次，flag就减少一次；从持仓为0到开仓之后，flag的值重新赋值为平仓反向的次数num}


if marketposition=0 and condition1 then  
        buy lot shares next bar at market;

if marketposition=0 and condition2 then
        sellshort lot shares next bar at market;

if marketposition=-1 and condition1 and flag>0 then
        buy lot shares next bar at market;

if marketposition=1 and condition2 and flag>0 then
        sellshort lot shares next bar at market;

if marketposition=1 and condition3 and flag=0 then
        sell next bar at market;

if marketposition=-1 and condition4 and flag=0 then
        buytocover next bar at market;
{condition1是买入进场的条件；condition2是卖出进场的条件；condition3和condition4都是出场条件}

注意：从代码的效率来说，这样并不高；您可以使用if else将整个代码优化一下。
