I’m trying to figure out a way to have some sort of bi-directional communication between node.js and MT4.

First goals:
– List open positions and orders and make them available to my node.js application
– Be able to close positions and cancel orders from node.js
– Fetch current balance from account

Second goals:
– On every new bar for a period, broadcast the last X bars to node.js
– Be able to open orders from node.js
– List deposits / withdrawals

I could partially reach those goals by tweaking your example EA and continuously push data to node.js which could sync my database, but still i wouldn’t be able cancel/open/close orders/positions from node.js.

Also using your example i could continuously query node for “pending actions” then execute the action and reply to node something like “closed order successfully”, but that seems to be a very ugly workaround.

I suspect on an ideal world i would have a node.js server on the same machine as MT4, issue a command to that node.js instance and then somehow “natively” call functions on MT4, but i still don’t know how to achieve this communication ( node.js ~> MT4 action ), but unfortunately i’m not sure what would be the easiest way.

Ideally i would avoid having to write DLLs or any other sort of “windows programming” on the machine, is there a way? For instance some command line access to MT4 that would execute a command and print some meaningful response?

Any ideas, recommendations and suggestions will will be highly appreciated.
