Mql4 指標不會自動更新

Question

我遇到了我正在處理的指標的一些問題，有人可以看看並告訴我為什么會導致這個問題嗎？

簡單地說，指標不刷新

說明：當我將指標附加到圖表並保持打開狀態時，一段時間后，當我附加具有類似參數的同一指標的另一個實例時，新指標會顯示與之前附加到圖表的線不同的線，即使我沒有附加新指標，只需雙擊當前附加的指標，然后單擊“確定”按鈕，它會更改先前繪制的蠟燭線，請查看屏幕截圖

有時變化太大，有時變化不大，但總有一些變化，這取決於我在指標上雙擊並按確定后多少條。

如果有人能指出我做錯了什么，我將不勝感激，謝謝

這是我的代碼：

我認為問題是你必須在緩沖區中聲明美元和歐元的所有 7 個變量，就像這樣......並將它們放在單獨的 for 循環中

for(int i = limit-1; i >= 0; i--)
EUR1[i] =  iRSI("EURUSD",PERIOD_CURRENT,R_Value,PRICE_CLOSE,i);
EUR2[i] =  iRSI("EURGBP",PERIOD_CURRENT,R_Value,PRICE_CLOSE,i);
EUR3[i] =  iRSI("EURJPY",PERIOD_CURRENT,R_Value,PRICE_CLOSE,i);
EUR4[i] =  iRSI("EURAUD",PERIOD_CURRENT,R_Value,PRICE_CLOSE,i);
EUR5[i] =  iRSI("EURCAD",PERIOD_CURRENT,R_Value,PRICE_CLOSE,i);
EUR6[i] =  iRSI("EURCHF",PERIOD_CURRENT,R_Value,PRICE_CLOSE,i);
EUR7[i] =  iRSI("EURNZD",PERIOD_CURRENT,R_Value,PRICE_CLOSE,i);
