Each time my Ea launches a trade,I usually receive this message: 555 Scalper XAUUSD,M5: Error opening BUY order : 130. Please what does this mean,aand how can I correct it?

Please use the search function for error code 130

1. Why did you post your MT4 question in the Root / MT5 General section instead of the MQL4 section, (bottom of the Root page?)
             General rules and best pratices of the Forum. - General - MQL5 programming forum
   Next time post in the correct place. The moderators will likely move this thread there soon.

2. Perhaps you should read the manual.
             Runtime Errors - Codes of Errors and Warnings - Constants, Enumerations and Structures - MQL4 Reference

   You can't move stops (or pending prices) closer to the market than the minimum: MODE_STOPLEVEL * _Point or SymbolInfoInteger(SYMBOL_TRADE_STOPS_LEVEL).
             Requirements and Limitations in Making Trades - Appendixes - MQL4 Tutorial

   On some ECN type brokers the value might be zero (broker doesn't know.) Use a minimum of two (2) PIPs.

3. Fix your broken code.
