I would like to know for those profitable hedge fund, are they apply similar strategies to different market? I think if a strategy works in an asset, there must be limitation on scaling up. So that they are doing multiple assets.
Depends on asset traded.
Forex can be done for 100M to 1Bn in a single trade without much issue.
Index futures also really liquid.
Small stocks will have issue
i use interactive broker. can anyone tell me the most liquid exchange for forex? and what is the symbols? I am new to forex. i guess forex is trading forex itself? so don't have something like contract expiry like futures?
