The following script uses a timer and works well in normal charts to comment current candle closing price every 1 second on chart. However, on offline chart, it only loads the closing price once and does not update it every second. Here is the code: void OnTimer() { int m=TimeSeconds(TimeLocal()); double CloseValue = Close[0]; //Current Candle Close Value string CloseValueString = DoubleToString(CloseValue,5); //Current price Comment( "Current value :",CloseValueString,"\n", "Candle time :",m ); }

Solved by adding the Refreshrates() function which updates data for the offline chart at the end of my function: void OnTimer() { int m=TimeSeconds(TimeLocal()); double CloseValue = Close[0]; //Current Candle Close Value string CloseValueString = DoubleToString(CloseValue,5); //Current price Comment( "Current value :",CloseValueString,"\n", "Candle time :",m ); RefreshRates(); }
