Hello Lobo, I agree with you using a text file to communicate between the programs is probably the best solution. I would start with MC first and check if you can access a file created with append in MT4. I tried a similar method last year but MC6 blocked the file access. PFabc

I am not sure the management of orders via a single file will be a reliable solution. Issues are starting with having 2 programs accessing the same file.
The email or the DLL integration of NinjaTrader and TradeStation are interesting. TradeStation Integration
with unfortunately no direct application for MT4.

Ok , @ pfabcTrader you gave me a very important hint , which has led me - after some intents on my own - straight into the MC support (we might have different versions of MC , I still have loaded MC7.4) : The team there than helped me out with two links : Universal DDE - MultiCharts in the newly created MC Wiki and some 2 videos , position 4 and 5 in the list of Videos When I than asked , if there would also be a way of shuffling tradedata from MT4-Brokerage into MC the answer was "No" (which is a reconfirm to me , from people which know about MC ) Ok, IŽll work on the connection , next step that is . But I really wanted to follow up also appreciating the post of pfabcTrader Lobo PS.: Nur nicht verzagen, sondern wagen! => and NEVER give up

Could you or for that matter anyone else please also share Excel screenshot to achieve above result? I am particularly interested about how/what you gave name to particular cell in excel? Tutorials on Multicharts site are very short.
