# 注意事項

1. 每次更新函數包後需注意源碼內 outputfile\_64.dll 的宣告路徑是否正確
2. 如果圖表內有掛載 data2，請記得將下列選項反勾選

![](/files/-MkGbYM5GVpfim1xMHH5)

3\.  \[**重要**]\[一大點價值設定] QuantBrains\_Connect會自動輸出 Multicharts （QuoteManager）內的一大點價值設定，請務必確認QM中的設定是正確的， 如為臺灣股票商品請設定為1000（1000股＝1張），股票期貨設定為2000

4\. lookbackdays 之設定為"天"數，請確認引用K棒數需大於這個數值。如為分線策略的引用K棒數請設定為 lookbackdays\*一天的K棒數（例如台指30分K的日盤，引用K棒數請設定為 lookbackdays\*10以上）。

5\. 確定圖表的歷史資料長度大於 lookbackdays 天數（可觀察回測圖表第一筆交易是否超過這個天數），一般評價分數如果顯示都是0，大部分原因是因為歷史資料長度不足。
