On early games, Duke game had no value. 538line was -549, could not get anything better. On last minutes I even offered -600 at Matchbook, trying to get a small bet on NC-Willmington (about +588 after commission), but no one bought. So, no bet.
Butler had value, 538line was -202, so I bought some -170 at Matchy 2 mins before gametime. Of course, a few seconds later price went down, so I added at prices averaging -165. Slightly overbet, total risk $253.
Got Connecticut at -158 matchbook (about -161 real), vs -175 538line. $89 risk.
Iowa St was best value of day. I placed some at good prices, but when trying to add at matchy the market it went off. Damn matchy, it listed 2:05 start time, so went off with "4 mins left". Underbet at $285 risk at -293 (vs -528), should have been double that amount.
Took Yale +210 for $165. Price went better a few minutes later, but decided not to add.
Some fun on Hampton-Virginia. I got a 443 cents arb
. 5dimes +6000, Matchy -5557 net. And both were +EV, as 538line was 5641. In such cases, the correct way is placing the limited side to the max (5d only allowed $12.5 risk), calculate the exact hedge on the other side (to win same amount regardless of who wins) and add the Kelly bet on top of it.
On afternoon games I got Kansas -6567 net at Matchy for small amount (tw $9.5) and Purdue -390 net at Matchy (tw $100).
Matchbook liquidity has been poor on moneylines. There is a market maker offering $500 on both sides on some games, about 3 cents better than Pinnacle (after commission it is barely better than pinny). And very few guys taking offers.
First results have been good. Butler, UConn and Iowa St all won, Yale looking good. I am currently $73 on the black. Will post another update after last game at night, with detailed balance.
