I'm not used to playing fast stocks like MAMA. How are you supposed to trade something like this when it's moving a point per minute? I tried a few market orders, and they just sat there for 10 seconds or so. (Aren't market orders immediate?) Should you just use a limit order with ISLD, assuming there's going to be ample liquidity? I think I must have cheated myself out of $5K not knowing how to get my trade executed efficiently.
