Can anyone help me the oncalculate() function is not being called in my programme
Please tell when is oncalculate() function called in MT5 and when will it not be called
OnCalculate is called when the indicator is loaded on the chart and when a new tick comes in.
There is no oncalculate function. Is your function form exactly matching one of the two forms? Post your code.
struct st_Bars //structure initialization
{
int Bar_1;
int Bar_2;
int Bar_3;
int Bar_4;
};
st_Bars Bars_Ext; // declaration of structure type variable

{
Trade_Symbol=Symbol();
Period_Trade=Period();
Dig=(int)SymbolInfoInteger(Trade_Symbol,SYMBOL_DIGITS);//number of decimal places in current symbol
//--- indicator buffers mapping
SetIndexBuffer(0,supportBuffer,INDICATOR_DATA);
SetIndexBuffer(1,resistanceBuffer,INDICATOR_DATA);
h_RSI=iRSI(Trade_Symbol,Period_Trade,Period_RSI,PRICE_CLOSE); //return handle of RSI indicator
if(h_RSI<0) Print("Incorrect handle of RSI ");
if(Analyze_Bars>Bars(Trade_Symbol,Period_Trade)) //if less bars in history for analysis,
{
Print("The history of the less",Analyze_Bars,"bar"); // than specified in bars parameter, then you need to tell this
Bars_H=Bars(Trade_Symbol,Period_Trade);
Print("Number of bars in history = ",Bars_H);

This is the code upto the oncalculate function
The code upto the deinit function is runnng but the oncalculate function is not being called
