この回答はGPT-4による自動生成回答です
コンパイルエラーの原因は、SetIndexBuffer関数のオーバーロードが曖昧であるためです。MQL5では、SetIndexBuffer関数には2つのバージョンがありますが、どちらも同じパラメータを持っています。この問題を解決するには、SetIndexBuffer関数の呼び出し時に、ENUM_INDEXBUFFER_TYPEパラメータを明示的に指定する必要があります。
以下の修正を行ってください。
OnInit関数内のSetIndexBuffer関数の呼び出しを以下のように変更します。
cpp
1SetIndexBuffer(0, G_ibuf_76, INDICATOR_DATA); 2SetIndexBuffer(1, G_ibuf_80, INDICATOR_DATA);
- 最後に、MQL5では
start関数の代わりにOnCalculate関数を使用する必要があります。start関数をOnCalculate関数に変更し、以下のように引数を追加します。
cpp
1int OnCalculate(const int rates_total, const int prev_calculated, const datetime &time[], const double &open[], const double &high[], const double &low[], const double &close[], const long &tick_volume[], const long &volume[], const int &spread[])
これでコンパイルエラーが解決されるはずです。
