CUSTOM EA/AUTOTRADER

I need a custom EA programmed for Metatrader 4. IM NOT SURE IF ITS POSSIBLE FOR ALL THE FEATURES I WILL NEED BUT ILL POST THEM ANYWAY. BASICALLY IT WILL HAVE TAKE ALERTS FROM EMAILS AND EXECUTE THEM IN ONE OF 3 OR 4 WAYS. i WOULD LIKE TO BE ABLE TO CHANGE WHICH WAY IT WILL EXECUTE CERTAIN TRADES. IT WILL EITHER HAVE TO EXECUTE THE TRADES HOW THEY COME IN, REVERSE THEM TO BE THE OPPOSITE OF THE ALERT(ALSO RECALCULATE THE ENTRY,EXIT AND STOP LOSS BASED ON SPREAD), OR REVERSE SOME BASED ON ALERT PREFIX/TYPE AND TRADE OTHERS NORMALLY. ALSO I WOULD LIKE IT TO RECORD HIGH AND LOWS DURING ITS DURATION(IF POSSIBLE) THERE MAY BE A FEW MORE THINGS ADDED BUT THEY WILL BE MINIMAL. PLEASE LET ME KNOW WHAT IS POSSIBLE AND NOT POSSIBLE IN YOUR BID. THANKS
