Mt4 and matlab connection

connection between matlab and MT4 data as follow,

1) in mt4 the forex history data with custom marked can be loaded into matlab, specifically, in the mt4 main  window I put some marks from arrows-> arrow up,  arrow down, stop etc 

    in some location.  then the whole set of the mt4 data including price,these marks, and the showed indicate can be loaded to matlab, in all time frame.

    in mt4 this  is probably a script.

2) in matlab, a matlab code to read the data from the mt4 in 1) and display windows similar to mt4,  

    a program developed by me to process the data to generate some trading signals to mt4 in both real time and a DLL which can be integrated to MT4 EA code.
