Ok, "ton" wasn't necesary.
The LIVE bets I've been showing have mostly been open and close positions, where I get each team as an underdog moneyline, on bets where I took EV pregame as well. I don't generally like selling back EV, but have a separate bankroll where that's what happens. I will buy a team as a dog, twice, then when they take the lead I'll look for market overreaction and take the other side as a dog and "close" one of those postions. I look for +EV in all trades.
It's like option trading over a position you hold, and sometimes going naked to throw the book off.
But any LIVE trading is good for the purpose of mixing it up and keeping the book happy. They don't mind if you venture to play the vig, it looks a bit "square" too. You can get limited there, but you can get limited anywhere. It's just best to mix it up.
The idea is to "disguise" your sharp action so they don't flag you.
