I have been watching the Market Depth on the ES for a while now, and am thoroughly confused. My intentions were to use it as a tool to better time short term scalps/swings (5-20 min in trade, 1.5-3 pt profit target). However, my instincts on supply/demand are often proven wrong. Has anyone had any success reading the ES market depth? Do the rules/strategies for Level II apply to the ES? Are there any hidden traps? Maybe I shouldn't even open that window on TWS!
