If you are using the ChartOpen Function , you need to remember: this function returns the opened chart ID. It is this identifier that must be used to draw on a new chart.

ChartOpen

Opens a new chart with the specified symbol and period.

long  ChartOpen(
   string           symbol,     // Symbol name
   ENUM_TIMEFRAMES  period      // Period
   );

Parameters

symbol

[in] Chart symbol. NULL means the symbol of the current chart (the Expert Advisor is attached to).

period

[in] Chart period (timeframe). Can be one of the ENUM_TIMEFRAMES values. 0 means the current chart period.

Return Value

If successful, it returns the opened chart ID. Otherwise returns 0.

Note

The maximum possible number of simultaneously open charts in the terminal can't exceed the CHARTS_MAX value.

ChartOpen() returns a long value, How can i access that long value without executing the ChartOpen(). I am running a multi symbol and multi timeframe EA on loops

  string symbolarray[];
  ArrayResize(symbolarray,SymbolsTotal(true));
  for(int i=0;i<ArraySize(symbolarray);i++){
  for(int j=0;j<ArraySize(TF);j++){
  string sym=SymbolName(i,true);

  // Strategy Logic

  ChartOpen(sym,TF[j]);

Use a styler - you will immediately see your error:

string symbolarray[];
ArrayResize(symbolarray,SymbolsTotal(true));
for(int i=0; i<ArraySize(symbolarray); i++)
  {
   for(int j=0; j<ArraySize(TF); j++)
     {
      string sym=SymbolName(i,true);
      // Strategy Logic
      ChartOpen(sym,TF[j]);
