策略無法執行QQ

請問XQ小幫手

小弟新手一枚，嘗試寫了一個當沖策略，但一直無法執行QQ，請問是哪邊寫錯惹

input: FiveMAPoint(17610);

input: PreviousClose(17506);

if time = 084500 then

value1 = open;

value2 = close;   /抓08:45~08:50期貨第1根K棒的開盤價與收盤價/

if time = 090500 then

value3 = open;

value4 = close;   /抓09:00~09:05期貨第4根K棒的開盤價與收盤價/ 

condition1 = value1 > PreviousClose and value2 > value1 and value4 > value2 and value4 > value3 and value4 > FiveMAPoint;    /判斷式/

if time > 090500 and condition1 = true then begin

buy(1,market);

end;

if time > 134445 then begin

   if position <> 0 then begin 

setPosition(0);

end;

end;
