  1. Finds the prefix, infix, and suffix used by the broker. Can remove or add them.
  2. Only if you want your code to work with different brokers.

 
Ask your broker.

Broker's use a variety of naming patterns: EURUSD, EURUSDc, EURUSDcheck, EURUSDct, EURUSDecn, EURUSDf, EURUSDi, EURUSDm, EURUSDme, EURUSDmicro, 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@”, “EURUSD_i”, “EURUSD-5”, “EURUSD-g”, “EURUSD-m”, “EURUSD-sb”, etc., “#FB”, “#TSLA”, and 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.
