Leg risk is when you are opening/closing a spread,and instead of sending out a spread order,you choose to buy/sell one side of the spread and then trade the other.Its called "legging" the spread,or you lifted a leg.Problem is,best case scenario you MAY get filled mid market,but if you lift a leg(close one side) and the market suddenly moves against you,you get smashed...
You are grasping at straws.
- You MAY getting filled at mid-market in any situation - or you MAY not.
- The market might move against you during the 15 seconds it take you to place your 2nd order - or it might move in your direction. You will not get "smashed".
