FX Blue - TradeCopy Receiver XAUUSDc,H1: Alert: Error #4112 most commonly means that you need to trade a different version of the symbol, by setting ForexSymbolSuffix or a CustomSymbolMapping

今天碰到fxblue跟单提示这个错误，反复调试，帐号也不能正常跟单，然后设置交易品种的后缀，指定喊单帐号和跟单帐号的对应品种代码，重启mt4，反复都不行。于是更换了中文跟单ea，发现还是不行。于是找了个下单ea，试试用ea下手动单，发现也不行。

到这里我才恍然大悟，mt4帐号，不支持ea交易了。没错，当你看到错误“#4112 ”代码时，通常就是说此账号不支持ea交易。
