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-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.
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 remove the adornments during processing.

Hi,
I am struggling to find a method that will return a string with the first 3 letters of a currency pair.
Similar to how the SYMBOL_CURRENCY_BASE returns the final 3 letters of a pair.
Any help or advise would be greatly appreciated!
