On Kalshi's 15-minute markets, a new round opens every quarter hour across 19 markets. That adds up to hundreds of chances a day. Most of them aren't worth taking. Here are seven signals that say skip.
1. The price is above your honest probability
The price is roughly the win rate you need. If a contract costs 93¢ and you can't honestly say it wins more than about 94% of the time after fees, there's no edge. Check the exact number in the break-even calculator.
2. The spread is wider than your edge
If buying costs 62¢ and selling gets 58¢, you're 4¢ down the moment you fill. An edge of a point or two doesn't survive that. (More in how to read the order book.)
3. There isn't enough size at the price
If only a handful of contracts sit at the best price, a normal-sized order walks up the book and your average cost rises. The trade you calculated isn't the trade you'll get.
4. Not enough time, or too much
Very early in a window, a small lead means little. In the last seconds, the book can thin out and fills get unreliable. Many traders set a band of time left inside which they'll trade, and skip everything outside it.
5. Your data is stale
If your price feed, the strike or the book is even a few seconds old in a fast market, your calculation is about a market that no longer exists. Skip until it's fresh.
6. You'd be adding to a losing day out of frustration
Bigger size after a loss is how small drawdowns become big ones. A daily loss limit that stops trading when it's hit removes that decision from the moment.
7. One loss would erase too many wins
At 93¢ one losing contract wipes out about 14 winning ones after fees. If your size means a single loss would ruin the week, the size is wrong even if the trade is right. See the full table in Kalshi fees and break-even.
Skipping is a result, not a failure
In our own 265 live trades, the work that mattered most was everything the bot didn't take. Writing down why you skipped is as useful as logging why you traded: over time it shows which rules are actually protecting you.
