求指導如何寫停利停損

//value2 = RSV, value3 = K, value4 = D

value1 = Stochastic(9,3,3,value2,value3,value4);

// K, D 都大於70且KD死叉

if value3 > 70 and value4 > 70 and value3 cross over value4 

then setposition(-1);

//停損停利

input: profit_point(10, "停利(點)");

input: loss_point(10, "停損(點)");

if Position = -1 and Filled = -1 then begin;

if profit_point < 15 then begin;

SetPosition(0);

end else if loss_point  > 18 and Close >= FilledAvgPrice + loss_point then begin;

SetPosition(0);

剛入門，寫一個台指期空單策略，想寫成：

停利：成本價-15就停利

停損：收盤價>成本價+18就市價停損

我按編譯會說最後一行有少東西

但如果只有這樣就編譯完成

//value2 = RSV, value3 = K, value4 = D

value1 = Stochastic(9,3,3,value2,value3,value4);

//停損停利

input: profit_point(10, "停利(點)");

input: loss_point(10, "停損(點)");

// K, D 都大於70且KD死叉

if value3 > 70 and value4 > 70 and value3 cross over value4 

then setposition(-1);

不知道哪裡出問題，求指導，非常感謝！！
