I've been watching the ES tonight, and I noticed that there are a ton of buy orders 1 tick below the low price of the session, which occurred during the opening 1 minute bar. They've been there ever since I noticed them a few minutes after the open. Does anybody know what this is? Is it some well known strategy? Seems counter-intuitive to me. I've attached a pic of the TS matrix window so you can see what I'm talking about.
