Bet sizing that keeps accounts open

Stake size is one of the easiest things for a book to read, so sizing that keeps accounts open comes down to four habits: bet round amounts, keep your stakes in a steady band instead of moving them with every change in your edge estimate, stop probing the maximum on every bet, and size each bet to what that market ordinarily takes. The expected value you give up doing this is small — usually cents per bet — and the worked numbers below show it.

Round numbers versus odd stakes

A stake of $47.13 does not come from a person deciding how much to bet on a game. It comes from a calculator — usually the Kelly criterion or an arbitrage split — and a pattern of stakes like that is an easy tell. Most customers bet $20, $25, $50 or $100. Rounding to the nearest $5 or $10 makes your stakes look like what they are: a decision about how much to bet.

Consistent sizing

Kelly-style sizing makes stakes jump around: a big bet when your edge estimate is large and a small one when it is marginal. To a book that is a readable signal — the stake itself reveals how good you think the price is, and the biggest stakes land on its worst prices. Many experienced bettors instead use a fixed unit, or two or three bands (one unit for most bets, two for the strongest), and pass on marginal edges rather than betting them small. That gives up some growth compared with exact Kelly and keeps stakes looking like normal betting.

Max-bet probing

Typing a large number into the slip to see the maximum, then betting exactly that maximum, is one of the clearest signs of a price-driven bettor, because recreational customers rarely care what the ceiling is. Books set limits per selection — DraftKings' house rules say every selection has limits set at its discretion — and when you hit one, the slip tells you. The same rules let you ask for a bet above the limit, which the book may accept in full, in part, or not at all. What you should not do is split a stake the book has capped into repeated identical bets: DraftKings' rules allow it to void every copy of the same bet except the first (in Massachusetts, with the regulator's approval). If a market's maximum is lower than you want, bet the part you want at that book and the rest somewhere else.

Stake size relative to the market

A $500 bet means different things on different markets. On an NFL spread, where books take large bets, it is ordinary. On a second-tier prop whose limit might be a small fraction of that, it is the whole limit — and a customer who repeatedly bets the whole limit of small markets is easy to spot. Keeping stakes on niche markets well below their maximums, and putting larger stakes on main markets, lines your sizing up with what the market can absorb. Which markets draw attention covers the markets themselves.

Doing it in TrueEdge

Settings has a Round suggested stakes control (Exact, Nearest $1 or Nearest $5) that applies to every stake TrueEdge suggests, including the figure a bet link copies to your clipboard, and a hard maximum per bet as a share of bankroll that no suggestion exceeds. Hedge legs have their own rounding setting. The positive EV walkthrough shows where suggested stakes appear, and the calculators walkthrough shows how to work a stake by hand.
