How to download data of symbol

Just_Mike: It's not unknown problem that function return 0 when historical data are not loaded. I would like to know how to load these data for different symbols. | It's automatic. When you get zero (the first time,) check the error code for ERR_HISTORY_WILL_UPDATED and wait 5 seconds and retry. See ArrayCopyRates - MQL4 Documentation Returned value and the example it links to in ArrayCopySeries - MQL4 Documentation |

Of course not. You'll have to have it remember that it needs to redo all bars (not just IndicatorCounted) the next tick after 5 seconds. |

Hi guys, I'm working on Indicator that use iClose function. It's not unknown problem that function return 0 when historical data are not loaded. I would like to know how to load these data for different symbols.
For example: I have my EURUSD chart opened and I've never opened USDCAD. I would add my indicator which need data from USDCAD. Is it possible to load these data? Thanks for reply!
