As a rule, this happens if: there are several types of trading accounts on the same trading server (trading accounts with different trading conditions). Postfixes are used to distinguish between types of trading accounts.

Same symbol on MT4 yet one with quote and other without quote

You will have to ask them.

Broker's use a variety of naming patterns: EURUSD, EURUSDc, EURUSDcheck, EURUSDct, EURUSDecn, EURUSDf, 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@”, “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.
