The only genuine edges I know of are both illegal....
1. Front-running
2. Trading on insider info
Lots of people perceive other as "edge", but likely is not.
JMV, FWIW....
Having the capital to affect price of the instrument one is trading
Knowing order flow (a tried and true pit trader's edge..., lost..., once the pits dried up)
Ability to be outright long..., and short - the same instrument
Ability to see resting orders
Control the mechanics - control the game
None illegal
