Which betting markets get you limited

The markets most likely to get an account limited are the ones where a retail book's prices are softest and its limits lowest: player props, minor leagues and small-conference college games, alternate lines and derivatives, and any price that has not yet moved after news or after the sharper books moved. Main-line spreads, totals and moneylines in the NFL, NBA, MLB and NHL draw the least, because those prices are efficient and books take large bets on them. The awkward part is that the soft markets are also where most edges are — so the question is how to balance them, not whether to avoid them.

Why main markets are safer

An NFL side attracts huge volume, and books copy each other and the sharp books closely, so its price is close to fair almost everywhere. A customer who wins a little on NFL sides looks like thousands of other customers, and the book can afford to be wrong by a fraction of a point because its limits reflect a deep, efficient market. Betting main markets is also what the typical customer does, so it is the bulk of an ordinary-looking account.

Why props and small markets draw attention

A book prices hundreds of player props per game, often from a model with little market input, and it sets low limits on them precisely because it knows some of those prices will be wrong. A customer who bets mostly props, and mostly the props that turn out to be mispriced, is telling the book they have a better model or faster information than it does. Minor leagues, lower-division soccer and obscure college games work the same way: thin markets, soft prices, low limits, close attention.

Stale lines

A stale line is a price that has not moved yet when the rest of the market has — after an injury report, a lineup, or a sharp book repricing. Betting it is betting a number the book is about to correct, and it is the most obvious pattern there is. It also carries a risk beyond limits: a book's rules may treat a price far out of line as an error. DraftKings' house rules list bets "placed at odds that are materially different" from the general market as one example of an error, and in Massachusetts they also allow, with the regulator's approval, voiding bets placed after an announcement that altered the odds. Check your book's house rules for its version.

Other patterns that draw attention

Alternate lines and derivative markets (first halves, quarters, team totals) are often priced from the main line with a formula, so their errors are systematic and a bettor who exploits them does so repeatedly. Early-week lines, before most of the market has bet, are where sharp money is known to move prices. Betting only one side of a pair of books — always the side that is off from the market — is the signature of arbitrage, whose risks include exactly this. None of these is off-limits. They just make up more of an account's story when they make up more of its bets.

Seeing the whole market at once

The odds board shows every book's price for the same market side by side, which is how you tell a main-market bet at a good price from a stale outlier before you place it — a lone price far from every other book is the one most likely to draw attention or be treated as an error.
