EA question. If I have EA orders running and my computer reboot, after restarting my MT4, would the EA still be able to manage the running orders?

 

Hello,


I have a question. If I have EA orders running and my computer reboot, after restarting my MT4, would the EA still be able to manage the running orders?



Thanks!

 

Depends on how it is coded.

EAs must be coded to recover. If the power fails, OS crashes, terminal or chart is accidentally closed, on the next tick, any static/global ticket variables will have been lost. You will have an open order but don't know it, so the EA will never try to close it, trail SL, etc. How are you going to recover? Use a OrderSelect / Position select loop to recover, or persistent storage (GV+flush or files) of ticket numbers required.

On a network disconnection you might get ERR_NO_RESULT or ERR_TRADE_TIMEOUT. There is nothing to be done, but log the error, return and wait for a reconnection and a new tick. Then reevaluate.  Was an order opened or is the condition still valid.

 
thanks
