What is the best way to buy a stock and sell it immediately with minimum costs and some control over the price? I would like to pay only $0.01 for BID/ASK spread + IB comission. I made a few rules: 1. Stocks with high liquidity (volume > 1 MIO) 2. Stock price > $50 3. Buy 4. Sell Since prices constantly change, should I use Snap to Mid order? Market order? Limit order?
