Symbol name issue in EA

New comment
 

I developed an EA for EURUSD only and it is working exactly as expected on some brokers. but when i tried it on exness, it started generating errors because of EURUSDm there.

i do not want to use a user input field for currency pair selection. how can i resolve this issue?

 

CurrencyBase

Gets the name of symbol base currency

CurrencyProfit

Gets the profit currency name

Broker's use a variety of naming patterns: EURUSD, EURUSDc, EURUSDct, EURUSDecn, EURUSDi, EURUSDm, EURUSDme, EURUSDpro, EURUSDt, "EUR.USD", "EUR/USD", "EURUSD!", "EURUSD#", "EURUSD.", "EURUSD..", "EURUSD.c", "EURUSD.cfx", "EURUSD.G", "EURUSD.i", "EURUSD.r", "EURUSD.SBe", "EURUSD.stp", "EURUSD+", "EURUSD-5", "EURUSD-g", "EURUSD-m", "EURUSD-sb", etc., Financial symbols with '-', '=', '_' and '+'

If the pattern your broker uses doesn't match the pattern of your signal provider's broker, you can't copy the signal/open a trade. Switch brokers to one that has that adornment.

If the naming pattern of your charts isn't exactly “BasQuo” then hard coded symbols fails.

Don't hard code things; just use the predefined _Symbol, or add/remove the adornments during processing.

No i do not want to hard code anything in my EA, if a solution exists in lib.

Will this work for trading only in EURUSD even if EA is attached to any other chart e.g. GBPUSD? I studied it but did not find a solution.

Of course not. Put it on the chart you want to trade.
