Strategy

Trade the Kalshi 15-minute Bitcoin up/down markets (series KXBTC15M) on early momentum. Each run: get_markets({series: "KXBTC15M"}) — the venue lists only the CURRENT 15-minute period. If it closes in under 6 minutes, do nothing. Otherwise pull get_price_history(minute, limit 15) and get_orderbook on it. If the last 3–5 minutes show a directional move of at least 5 points (YES price up → buy YES; YES price down → buy NO) and the ask you would pay is between 30 and 80, buy 5 contracts on the side of the move. This book moves several cents between your read and your order: set your limit 4 cents ABOVE the ask you saw — you still pay only displayed prices, and the order fills instead of resting. No clear move → do nothing. Never hold more than one position at a time; positions settle themselves within 15 minutes. Sizing is FIXED: every order is exactly 5 contracts (results are compared across a fleet; do not size by conviction). Hold positions to settlement unless the strategy says otherwise. End with a short report: the market you looked at, the numbers you saw, and what you did.

Run complete. Reviewed KXBTC15M-26AUG292100-00, closing 01:00 UTC with about 10 minutes remaining.

YES minute history was 44 → 46 → 43 → 54 → 66, a clear +22-point directional move over the last five observations. The YES book showed a 67¢ ask with ample displayed depth; the corresponding ask was within the 30–80¢ entry range. I bought 5 YES contracts using a 71¢ reservation limit, filling all 5 at 67¢ with an 8¢ fee.

No resting orders remain. The position should be held to settlement under the strategy. Next run should check whether this market settled and review the portfolio before considering any new entry.

4 stepsAug 30, 00:35 UTC

Run complete. Reviewed KXBTC15M-26AUG292045-45, closing 00:45 UTC with about 10 minutes remaining.

YES minute history was 43 → 63 → 45 → 51 → 46. Although the net change over five observations was +3 points, the path was highly volatile and did not show a clear directional 5-point momentum move. The book was consistent with the market quote: YES bid/ask 46/48, with substantial displayed depth; however, neither YES nor NO met the strategy’s clear-momentum entry condition.

I made no trade. No positions or resting orders remain. Next run should inspect the then-current KXBTC15M market, confirm sufficient time remains, and require a clean directional history rather than reacting to this choppy sequence.

4 stepsAug 30, 00:20 UTC

Run complete. Reviewed KXBTC15M-26AUG292030-30, closing 00:30 UTC with about 10 minutes remaining.

YES minute history was 67 → 72 → 84 → 80 → 84: a net rise of 12 points over the last five minutes, satisfying the momentum threshold, but the current order book is crossed/inconsistent with the market quote (market shows 76/77 while displayed levels show bids through 79 and asks starting at 80). The payable YES ask from the market quote is 77¢, within the allowed range, but the anomalous book makes execution interpretation unreliable. I made no trade rather than enter on potentially stale or inconsistent liquidity.

No positions or resting orders remain. Next run should inspect the newly current 15-minute market and verify quote/book consistency before trading.

4 stepsAug 30, 00:05 UTC

Run complete. Reviewed KXBTC15M-26AUG292015-15, closing 00:15 UTC with roughly 10 minutes remaining.

YES minute history was 43 → 37 → 49 → 42 → 38. Although volatile, the recent sequence is down 11 points from 49 and lacks a consistent directional move over the last 3–5 minutes. The YES ask was 39¢ with substantial displayed depth; buying NO would require using the YES bid, equivalent to about 62¢. Since there was no clear momentum signal, I made no trade.

No positions or resting orders remain. Next run should inspect the newly current 15-minute market and repeat the momentum check.

5 stepsAug 29, 23:50 UTC

Run complete. Reviewed KXBTC15M-26AUG292000-00, closing 00:00 UTC with about 10 minutes remaining.

YES minute history was 55 → 59 → 58 → 64 → 67, showing a clear upward move of 9 points over the recent window. The YES ask was 62¢, within the required 30–80¢ range, with substantial displayed liquidity.

Bought 5 YES contracts using a 71¢ limit; all filled at 62¢, with a 9¢ fee. No resting orders remain. Position should be held to settlement under the strategy. Next run should check settlement/position status first and avoid a new entry while this position is held.

Run complete. Reviewed KXBTC15M-26AUG291945-45, closing 23:45 UTC with about 10 minutes remaining.

YES minute history was 58 → 48 → 49 → 51 → 38. The latest move was a clear 13-point decline, qualifying for the downside momentum signal. YES ask was 38¢, so the corresponding NO ask was 62¢, within the 30–80¢ range. The order book had sufficient liquidity.

Bought 5 NO contracts with a 66¢ limit; all filled at 62¢, with a 9¢ fee. No resting orders remain. Position should be held to settlement under the strategy. Next run should check settlement/position status first and avoid any new entry while this position is held.

4 stepsAug 29, 23:20 UTC

Run complete. Reviewed KXBTC15M-26AUG291930-30, closing 23:30 UTC; approximately 10 minutes remained.

YES minute history was 38 → 47 → 59 → 53 → 55. Although there was a sharp earlier rise, the latest 2-minute movement was downward and the recent sequence did not provide a clean qualifying directional signal under the 5-point momentum rule. The YES ask was 58¢, within the allowed range, with substantial depth, but the signal was ambiguous.

No trade made. No positions or resting orders. Cash remains 5,444¢ and realized P&L remains −4,556¢. Next run should check the next current KXBTC15M period and require a clearer recent move before entering.

5 stepsAug 29, 23:05 UTC

Run complete — reviewed KXBTC15M-26AUG291915-15, closing 23:15 UTC with about 10 minutes remaining.

YES minute history was 54 → 62 → 64 → 67 → 51, a 16-point decline on the latest move and well beyond the 5-point NO momentum threshold. The YES bid was 54¢, implying a 46¢ NO ask; displayed liquidity supported the trade.

Bought 5 NO contracts with a 53¢ reservation limit; all filled at 46¢ each, with a 9¢ fee. No resting orders remain. Hold to settlement. Next run should check settlement/result and portfolio state before reviewing the next current period.

YES minute history was 60 → 63 → 67 → 62 → 56, a 7-point decline over the last four observations, qualifying for a NO momentum entry. The YES bid was 68¢, implying a NO ask of 32¢; the order book showed the executable NO level at 33¢, within the 30–80¢ range.

Bought 5 NO contracts, using a 36¢ reservation limit; all filled at 33¢ each, with an 8¢ fee. No resting orders remain. Hold to settlement. Next run should check settlement/result and portfolio state before reviewing the next current period.

YES minute history: 50 → 57 → 55 → 54 → 48. This is a net 9-point downward move over the observed window, qualifying for a NO momentum entry. The YES book showed bids at 56¢ and the corresponding NO buy ask was 44¢, within the 30–80¢ range.

Bought the required 5 NO contracts, filled at 44¢ each, with 9¢ total fee. No resting orders remain. Position should be held to settlement; next run should check settlement/result and portfolio state.
