XS間隔時間交易的問題

您好，因為我的交易策略，進場後，持有區間太短，所以我想用quit_in_interval 來間隔，但卻失敗，請問可以如何改進呢?  謝謝。

var: intraBarPersist Quit_in_interval(0); //交易間隔分鐘

var: intraBarPersist last_buy_time(0);

If BarFreq = "min" then begin Quit_in_interval=BarInterval+5;   //如果是5分K，應該間隔6分鐘

//間隔一段時間，再進行下一筆交易

if position = 0 and filled = 0 and condition1 = true and currentTime > timeadd (last_buy_time ,"M",Quit_in_interval) then setposition(-1);

last_buy_time =currentTime;

print(date,time,last_buy_time);

end;

//and currentTime >= last_buy_time+1

//停利

if position = -1 and filled = -1  and condition2 =true  then setposition(0);

print(date,time,last_buy_time+20);

//停損

if position = -1 and filled = -1  and condition1 =true  then setposition(0);
