Symbol Interface - assigning a value to it

Hi all,

I am trying to create a cAlgo BOT, which will run in a single chart only, and should be able to open trades for any currency pair (i.e for other charts)

Now, to open an order for another currency pair (rather than the currency pair of the current chart), I need to update the Interface Symbol, with my target currency pair. Then pass the Symbol to ExecuteMarketOrder API.

Something like Symbol.Code = "USDJPY", assuming that my BOT is running in "EURUSD" or any other chart.

However since Symbol.Code is read only, as such I am unable to understand how to pass my target currency pair?

Or maybe my query should be re-phrased as to how to open trades for different Symbols, other than the symbol for the current chart?

Thanks,
