Hi,
I'm a French Professional Developer and I'm working in one of the Top Invesment Bank of France.
I'm working with Metatrader since several years on big projects: EA, Indicators, scripts, external components, etc.
I even developed some time ago the tool Mql2mq4 that you know can to be able to automatically migrate its EA from MetaTrader 2 to MetaTrader 4.
For your project without more details it is diffcult to give you a good bid, we need to exchange together to define the platform, the market and the exact strategy to implement.
Please consult my profil and do not hesitate to contact me to discuss about your requests, needs and, perhaps, our new collaboration :-)
Thanks.
Regards
Greg
