BASK TEST CODE問題

scottvision

小弟新手一試用MACD升穿SIGNAL為買入
MACD跌穿SIGNAL為賣出
相反亦然

A = MACD (Close,19,39);
B = Signal (Close,19,39,9);
SetPositionSize(1,spsShares);
//Open long
Buy = Cross(A,B);
//close long
Sell = Cross(B,A);
//open short
Short = Sell;
//close short
Cover = Buy;

但BACKTEST時就出現too many aurgment(LN:2 ,col:25)
點解呢??

Sirius

too many aurgment(LN:2 ,col:25)

問題出在第2行，25欄
signal()只有3個argument，你寫了4個進去了

scottvision

B = Signal (Close,19,39,9);
應該如何寫?
SIGNAL是3個數值??

我不懂 AmiBroker 語法. ... 但你可以參考一下底下 Signal 的說明網頁.

改成咁就得：
A = MACD (19,39);
B = Signal (19,39,9);
