MQL4 proramming

I am in need to have an EA coded which has to do? 4 things, (and I guess is pretty simple): [login to view URL] the historic data through DDE protocol to a *.CSV file on start up once (in a loop for every bar, I guess). [login to view URL] the contents of the DataWindow for the last (most recent bar)? to another? *.CSV file continuously [login to view URL] trade data (buy/sell action, SL and TP) from a third *.CSV file [login to view URL] trade in the following fashion: - open position through market order only, without setting SL and TP in advance - monitors price action continuously and executes SL/TP when proper, to close trade.
