IF there are some guys that guys giving you that amount of fund you can do following
- you can tell them that you have no clue about a good broker and a good platform even about trading. and advise them to find pro trader.
- if you would like to manage that fund, in your situation good broker and good platform will not change anything due you will unfortunatelly loose all fund. you can use any!!
- instead of doing it slowly and spending hours infront of screen, give a chance to VEGAS. it can be more fun.
