Middle betting

What a middle is

Say one book offers Over 109.5 and another offers Under 110.5, both at -110. A total of 110 wins both tickets. Any lower total wins only the Under; any higher total wins only the Over. With $100 on each leg, the settlement looks like this:

The middle window is the result or range where both legs win. BreadSync sizes the second stake so the two miss outcomes cost the same. A whole-number edge can create a push middle instead: Over 109.5 with Under 110 wins one ticket and refunds the other at exactly 110. That pays less than both bets winning, so the row labels it “Middle Push” and models the refund separately.

Compare overlapping spread and total lines across your available books, with the hit and miss outcomes shown separately.

1. 1.Choose “Leagues”, “Books” and a date. In “Markets”, keep the spreads, totals or periods you are willing to bet; the finder includes their available alternate lines.
2. 2.Set “Bet Size” for the first leg. The other stake is sized so either result outside the window has the same cost.
3. 3.Sort by “Jackpot” for the largest hit, “Dollars” for the best miss result, “Percent” for arbs first and then the lowest hold, or “Event Time” for urgency.
4. 4.Read the window, profit if it hits, estimated chance and hold. Expand the row to see every settlement band and each leg’s result.
5. 5.Compare both live slips. If an odd or accepted stake differs, type the real value into the row and use the recalculated amount.

The hit chance, when shown, is a no-vig estimate from the surrounding line ladder. It is not a game prediction. If the market does not have enough two-sided prices just outside the window, the row says “chance n/a” instead of inventing one. Hold is the price paid for the overlap; a smaller loss can be better than a larger headline jackpot.

Make sure the two bets really overlap

• Same event and start time. A rematch or duplicate team name is not the same game.
• Same market and period. A full-game total cannot middle a team total, first-half total or regulation-only total.
• Opposite sides, in the right order. Over the lower number with Under the higher number creates a total window. For spreads, the two teams' lines must leave a scoring-margin window where both cover.
• Same settlement rules. Check overtime, postponements, listed pitchers and any house rule that can make one ticket void while the other stands.

The Middles finder covers spreads and totals, not player props. A player-prop window whose prices already profit on every result can appear as an arb middle on the Arbitrage page.

Watch out: alternate lines can look alike while describing different periods or team totals. Treat an unusually wide or cheap window as a reason to inspect both slips, not as proof that the books made a large mistake.

Middle versus arbitrage

A negative hold on a Middles row is the special third case: its two prices already form an arb before the overlap is counted. For an ordinary middle, the green jackpot does not erase the red miss cost. Judge the whole outcome table, not one number.

Line movement and partial acceptance

Prepare both slips first. Submit the leg most likely to move or be limited, usually the outlying or thinner alternate line, then place the other without delay. A middle is exposed after the first acceptance: there is no fixed downside until the second leg is accepted.

• If the price moves: type the new price into that odds field. The stakes, hit result and miss result update immediately. Continue only if the new tradeoff is still acceptable.
• If only part is accepted: type the amount that actually landed into that stake field. Hedge the recalculated amount, not the amount you requested.
• If the line itself moves: stop and re-check the window. A different point changes which scores win both bets; an inverted gap can make both tickets lose.
• If the second leg is refused: do not keep retrying the old plan. Use the mid-hedge recovery steps for the open first ticket.

Once both tickets are accepted, use the row's green bookmark to add both to Tracker. Check the prefilled books, lines, odds and stakes against the receipts before saving.
