I have an EA that has correctly opened some trades. The magic number is say 200010. There could be a number of trades open using group numbers so that there is say 3 trades with magic numbers of 200010, 200011 and 200012.
Can I add a new EA on a different chart of the same currency that will close the trades from the first EA when certain conditions are met? If so what magic number should I use for the new EA? Do I also use 200010? The trade I open with this EA should I use group 3 so that it's magic number is 200013?
When I close the trades from the new EA I also want it to close the trades of the first EA. When the conditions are met on EA 2 do I simply use block Close Trades with Group numbers entered of 0,1,2,3?
