because MT4 doesn't have multi-account software (which usually needed by fund manager who control lot of MT Accounts).. i have an idea to develop it...
i don't understand about MT API.. so i try to figure it out using EA...

i'm looking for someone to code it and share here

it must contains 2 EA, 1 reader and 1 follower

Reader EA will read any position opened by "human"...
and Follower EA will syncronize it...

for example, a computer run 5 MT,
1 of them controlled by human, and 4 of them controlled by EA.

EA read the transaction by read it one by one and write into a (or multiple) file... than the Follower EA, will read the file, and syncronize it...

i think.. it's quite difficult to recognize the command, so from the simplest way.... what about "only buy/sell transaction, and close it"...

so, we only make Follower EA that read the file...
only 3 command can be read
buy,eurusd,0.1 -> it means buy 0,1 lot eurusd at current price
sell,----------

close,#200606241729 -> yyyymmddhhmm -> it will close transaction with comment #200606241729

for the reader, we can make a vb based program to write some command at the file....

so we click the "buy" button on the program, then lot of MTs that run "Follower EA" will open transaction....

maybe somebody interested to develop it.....
