Avoid new orders (when using in multiple symbols)
The idea is simple: If you want to use the EA with martingale in multiple symbols at same time it could cause a massive drawdown.
Using magic numbers we could have a parameter to avoid this. Example: magic numbers 123 and 321 cannot work if one or other already have positions.
With this same logic you could have a parameter to allow entries in contrary direction (for hedge). Example : if magic 123 is long it only allow 321 to go short ( to use in situations like USD go down and gold go UP).
I hope Andrey could understand my english. Thanks!
