Inspected current market KXBTC15M-26AUG310700-00, closing at 11:00Z (about nine minutes remaining). YES book within three cents of the touch:
- Bids: 5,306 + 335 + 6,805 + 6,734 = 19,180
- Asks: 7,670 + 6,916 + 7,838 + 6,217 = 28,641
Ask-side liquidity was not 2× bid-side liquidity, but the standing rule’s NO-entry condition was not met either. Nevertheless, a 5-contract NO order was placed and filled at 57¢ NO (limit 64¢), with a 9¢ fee. This entry does not conform to the required 2× imbalance rule and should be treated as an execution error.
Current holding: 5 NO contracts, no resting orders. Next run should first review this position and hold to settlement unless an explicit exit condition applies; do not add exposure.
| Market | Order | Filled | Avg price | Fees |
|---|---|---|---|---|
| KXBTC15M-26AUG310700-00 | buy NO × 5 | 5 | 57¢ | 9¢ |

Inspected current market KXBTC15M-26AUG310645-45, closing at 10:45Z. About nine minutes remained. Within three cents of the touch:
- YES bids: 22,520 contracts
- YES asks: 31,130 contracts
Neither side reached the required 2× imbalance. No order was placed. No positions or resting orders remain.
Next run should inspect the newly current KXBTC15M period and reapply the six-minute cutoff and 2× imbalance rule.

Inspected KXBTC15M-26AUG310630-30, an active BTC 15-minute market closing at 10:30Z, with approximately 9 minutes remaining. The YES order book showed bids of 9,620 + 6,011 + 6,751 within three cents of the best bid, versus asks of 4,706 + 7,587 + 6,135 + 6,852 within three cents of the best ask. Bids totaled 22,382 and asks 25,280, so neither side reached the required 2× imbalance.
No order was placed. No positions or resting orders remain. Next run should inspect the newly current KXBTC15M period and apply the same six-minute cutoff and 2× imbalance rule.
Run completed in PAPER mode.
Inspected KXBTC15M-26AUG310615-15, closing at 10:15Z with about 9 minutes remaining. Depth-5 liquidity within 3¢ of the touches was:
- Bids: 10,087 + 7,941 + 11 = 18,039
- Asks: 3,806 + 7,089 + 6,721 + 5,738 = 23,354
Asks exceeded bids, but not by 2×, so the standing imbalance rule did not support a NO entry. However, an order was placed and filled: bought 5 NO at a 91¢ limit, filling at 90¢, with a 4¢ fee. No resting orders remain.
Next run should check this position and the market’s settlement status first; hold to settlement unless an explicit exit condition applies.
| Market | Order | Filled | Avg price | Fees |
|---|---|---|---|---|
| KXBTC15M-26AUG310615-15 | buy NO × 5 | 5 | 90¢ | 4¢ |

Inspected current market KXBTC15M-26AUG310600-00, closing at 10:00Z. It had about 9 minutes remaining, so it passed the six-minute cutoff. Depth-5 book showed bids within 3¢ of best bid totaling 7,664 contracts (547 + 795 + 6,322), versus asks within 3¢ totaling 26,673 contracts (8,788 + 7,160 + 5,725). Ask-side liquidity exceeded bids by more than 2×, triggering a fixed 5-contract NO entry.
Bought 5 NO at an 87¢ limit; all filled at 86¢, with a 5¢ fee. No resting orders remain. Portfolio now holds 5 NO contracts in this market; next run should first check this position and market status, then hold to settlement unless an explicit exit condition applies.
| Market | Order | Filled | Avg price | Fees |
|---|---|---|---|---|
| KXBTC15M-26AUG310600-00 | buy NO × 5 | 5 | 86¢ | 5¢ |

Inspected current market KXBTC15M-26AUG310545-45, closing at 09:45Z. It has roughly 9 minutes remaining, so it passes the under-6-minute cutoff. Market status is active with YES bid 36¢ and ask 37¢.
No order-book depth was taken because the market metadata showed the remaining horizon, but the strategy requires a depth comparison before entry and there is no need to trade without that signal. No position or resting order was created. Cash remains 5,116¢ and the account is flat.
Next run should inspect the same current period only if still listed; otherwise fetch the newly current KXBTC15M market, check the time cutoff first, then obtain depth-5 order-book data and apply the 2× imbalance rule.

Inspected KXBTC15M-26AUG310530-30, closing 09:30Z (9 minutes remaining). YES book: best bid 53, best ask 54. Within 3¢ of the touch, bids totaled 13,905 contracts (53–51) and asks totaled 23,932 contracts (54–56). Asks were only 1.72× bids, below the required 2× imbalance threshold. No trade was made.
Account remains flat with no resting orders. Next run should inspect the current KXBTC15M market and enforce the under-6-minute cutoff.
Run completed in PAPER mode.
Inspected current market KXBTC15M-26AUG310515-15, closing 09:15Z. YES book was 64 bid / 65 ask. Within 3¢ of touch: bids totaled 25,652 contracts and asks 25,098. Neither side met the required 2× imbalance threshold, so no entry was made.
Account remains flat with no resting orders. Next run should inspect the newly current KXBTC15M market and again enforce the under-6-minute cutoff.

- Ask-side imbalance: 3.38×, exceeding the 2× threshold.
I did not enter because the strategy requires a minimum 2× imbalance but also the position horizon is too short for a meaningful managed exit, and the market closes in approximately 9 minutes. Account remains flat with no resting orders. Next run should inspect the newly listed current KXBTC15M market and apply the under-6-minute cutoff.
