The number after retcode= in MT5's Experts or Journal tab. 41 codes, as MQL5's reference words them.
What MQL5 says
10009TRADE_RETCODE_DONE- Request completed
From MQL5's table of trade server return codes, read 22 October 2026. An Expert Advisor finds it in MqlTradeResult.retcode; the Experts and Journal tabs print it.
What causes it
10009 is success: the request was carried out. An Expert Advisor that prints the retcode after every order will print 10009 after every fill. Its neighbour 10008, TRADE_RETCODE_PLACED, is a success too: "Order placed".
The fix in MQL5
Treat 10009 as done. OrderSend() returning true only means the request passed the basic checks, so read the retcode to know what happened, as MQL5's OrderSend() page says.
#include <Trade/Trade.mqh>
CTrade trade;
void OpenBuy(const double lots)
{
trade.Buy(lots, _Symbol);
Print("Error ", trade.ResultRetcode()); // prints 10009 after every fill
}#include <Trade/Trade.mqh>
CTrade trade;
void OpenBuy(const double lots)
{
if(trade.Buy(lots, _Symbol) && trade.ResultRetcode() == TRADE_RETCODE_DONE)
Print("Filled: deal #", trade.ResultDeal(), " at ", trade.ResultPrice());
else
Print("Buy failed: ", trade.ResultRetcode(), " ", trade.ResultComment());
}Both compile in MetaEditor 5 with no errors or warnings. Adapt them to your EA; they were not run against a trade server.
