I'd like to know the best way to execute a large order for a thinly traded stock. Since I'm at work during the day, I'd like for the entry and exit to be at either market open or close. Let's say open for this example because that's what's easier for me (I can do it in the evening or morning before work). I think think of 3 possiblities: 1 - Use market on open 2 - Use IB's scale feature to scale the order 3 - Use a limit order and put the limit at something like yesterday's close or today's open Does any one have an advantage? My main concern is driving the price up (or down) with my order. I'm currently doing the #1 (MOO) but I'm trading 100 lot shares to start out. Thanks for sharing your opinions and experiences.
