What happen if I close and restart an EA?
What happen if I close and restart an EA?
I play around a little bit with different EAs. Following question came up:
If an EA opens one or more trades, and then I close and restart the EA (or MT4), I don't see the opening of the position anymore on the chart. What happened:
1. It closed the position immidiately 
2. It "forgot" the open position and never closes it again >:(
3. It closes the position according the strategy 
Great question! When you close and restart an EA (Expert Advisor), what happens largely depends on how the EA has been programmed. Here's a breakdown of the options you mentioned:
It closed the position immediately: Some EAs might indeed close the position as soon as you stop or restart them. This could be due to the EA not having a mechanism to remember and manage its open trades.
It "forgot" the open position and never closes it again: This isn't ideal and can be a problem if the EA doesn't have proper trade management capabilities. It's important for EAs to remember their open trades, even after a restart.
It closes the position according to the strategy: This is the best-case scenario. Well-coded EAs typically use a "magic number" to identify their trades, and they can continue to manage these trades according to the strategy even after a restart. So, option #3 is what you'd hope for.
Expertfx has provided an excellent explanation. Good EAs indeed use a magic number or other trade identification mechanisms, allowing them to continue functioning according to their programmed strategy after a restart. So, it's essential to choose or develop EAs that exhibit this behavior.
Now, let's evaluate why these functions are good:
Option 1 (Immediate closure): This could be useful if you want the EA to exit trades quickly in case of any issues or unexpected market movements. However, it's not very flexible.
Option 2 (Forget and never close): This is usually not a desired outcome. EAs should ideally remember and manage their trades properly.
Option 3 (Closing according to strategy): This is the most favorable because it allows the EA to continue managing trades in line with the chosen strategy, even after a restart. It provides flexibility and is often preferred by traders.
A good function to have in an EA would be the ability to set specific behaviors for handling open trades upon a restart, giving traders more control over how the EA manages their positions. Additionally, providing notifications or logs about the EA's actions during a restart could be valuable for transparency and troubleshooting.
