openclaw skills install polymarket-btc-up-down-traderTrade Polymarket BTC daily and weekly UP/DOWN markets with empirically-anchored exit discipline. Enters on CEX momentum divergence; exits automatically on time cap, volume spike, or target capture. Use when the user wants to trade BTC direction markets (hours/days duration), not fast 5-minute markets.
openclaw skills install polymarket-btc-up-down-traderTrade Polymarket's BTC daily and weekly UP/DOWN markets with built-in exit discipline. Enters on Binance momentum signals, exits automatically before resolution tail risk bites.
Polymarket only. All trades execute on Polymarket with real USDC. Use
--livefor real trades; default is dry run.
Not for fast (5m/15m) markets. Use
polymarket-fast-loopfor those. This skill targets daily and weekly BTC direction markets with hours-to-days of duration.
⚠️ BTC UP/DOWN markets carry Polymarket's crypto taker fee. Effective rate is 3.5% at 50¢, up to ~6.6% on cheap shares. Makers pay 0% and earn a 20% rebate from collected taker fees. Factor this into your minimum edge threshold.

| Setting | Default | Env Var | Description |
|---|---|---|---|
exit_before_resolution_hours | 1.0 | SIMMER_BTCUD_EXIT_BEFORE_RESOLUTION_HOURS | Close position this many hours before scheduled resolution. Disable with 0. |
volume_spike_exit_multiplier | 3.0 | SIMMER_BTCUD_VOLUME_SPIKE_MULTIPLIER | Exit when 10-minute CLOB volume hits N× the rolling baseline. Disable with 0. |
target_hit_capture_pct | 0.85 | SIMMER_BTCUD_TARGET_HIT_CAPTURE_PCT | Exit when position has captured 85% of the theoretical max gain. Disable with 0. |
volume_baseline_windows | 6 | SIMMER_BTCUD_VOLUME_BASELINE_WINDOWS | Number of prior 10-minute windows used to compute volume baseline. |
Why these defaults? Exit behavior on short-dated prediction markets skews heavily toward early exits — the final hours before resolution compress remaining upside while tail risk (last-minute reversals, oracle variance) stays constant. The defaults are calibrated to exit early while capturing the bulk of the move. Empirical work on short-dated crypto UP/DOWN exit patterns informed the calibration; adjust based on your own backtest results.
| Setting | Default | Env Var | Description |
|---|---|---|---|
entry_threshold | 0.05 | SIMMER_BTCUD_ENTRY_THRESHOLD | Min discount from 50¢ toward the momentum-opposing side. Entry only fires when the market disagrees with momentum: UP signal requires YES < 0.50 (edge = 0.50 − YES); DOWN signal requires YES > 0.50 (edge = YES − 0.50). Skips when market already agrees with momentum. |
min_momentum_pct | 0.3 | SIMMER_BTCUD_MOMENTUM_THRESHOLD | Min BTC % move (30-min lookback) to trigger |
max_position | 10.0 | SIMMER_BTCUD_MAX_POSITION_USD | Max $ per trade |
daily_budget | 50.0 | SIMMER_BTCUD_DAILY_BUDGET_USD | Max total entry spend per UTC day |
lookback_minutes | 30 | SIMMER_BTCUD_LOOKBACK_MINUTES | Lookback window for BTC momentum signal |
min_hours_to_resolution | 4.0 | SIMMER_BTCUD_MIN_HOURS_TO_RESOLUTION | Skip entry if market resolves in fewer than N hours |

Each run cycle evaluates open positions against three triggers, in priority order:
time_cap — Time-based exitCloses position when the market is within exit_before_resolution_hours of resolution.
hours_to_resolution ≤ exit_before_resolution_hours → EXIT (time_cap)
This is the hard floor. Holding to settlement adds tail risk (oracle variance, thin liquidity, last-minute manipulation) with little remaining upside on a near-resolved market.
target_hit — Profit capture exitCloses position when it has captured target_hit_capture_pct of the theoretical maximum gain.
YES positions: (current_price - entry_price) / (1.0 - entry_price) ≥ 0.85 → EXIT (target_hit)
NO positions: (entry_price - current_price) / entry_price ≥ 0.85 → EXIT (target_hit)
Example: Bought YES at $0.40. Maximum gain = 1.0 - 0.40 = $0.60/share. At $0.91, captured = (0.91 - 0.40) / 0.60 = 85% → exit.
volume_spike — Smart-money volume exitCloses position when 10-minute CLOB volume exceeds volume_spike_exit_multiplier× the rolling baseline.
current_10m_volume / avg_baseline_volume ≥ 3.0 → EXIT (volume_spike)
A sudden surge in volume near resolution typically signals that informed traders have positioned ahead of outcome certainty. Exiting into the spike captures the liquidity premium.
Every exit logs one of four reasons:
| Reason | Trigger |
|---|---|
time_cap | Hours to resolution ≤ exit_before_resolution_hours |
target_hit | Captured ≥ target_hit_capture_pct of max gain |
volume_spike | 10m volume ≥ volume_spike_exit_multiplier × baseline |
