There are many different things to consider while choosing Forex platforms. The first thing being, what kind of trader are you?
Are you looking for ease of use? (entry and exit orders) If you are a scalper it is important that you find a platform that allows you to enter and exit the market with the least amount of clicks and ease of use.
Do you trade longer term and looking for a feature rich platform with great charting?
As far as a platform is concerned there are many different variables MT4 is obviously the most used because
1. It is free
2. there charting is decent
3. custom indicators
Just to name a few reasons, however when considering getting into the business on a asset management scale I don't think it is used much.
ex. I don't think you will find any fund managers using it.
I myself started on that platform and have sense then moved on to a proprietary system - it suited my needs...
many professional platforms have an upfront cost ranging in the thousands and usually a monthly data feed for a couple hundred bucks. You could look at it as overhead for your business in a way.
These are just a couple pointers I have... Good luck in your search!
