When running my EA on MT4 Demo account, it seems to only trade in one direction when backtesting. In the journal it shows the Buys and Sells, but the Sells show an error 138. What does this mean and how do I fix it?
Mql4 Error 138 Requote
Error 138 means that the broker replied with a "Requote" signal to your expert advisor's OrderSend() function call. In other words, the price used in the order is outdated compared to the current market price.

  • A "sell" position opens at the Bid price and closes at the Ask price.
