| description | Trade Polymarket 5-minute crypto fast markets using 1-minute candle body analysis and volume surge detection from Binance. Scans BTC, ETH, SOL, XRP, BNB simultaneously and picks the strongest signal each cycle. Enters when the last candle has a strong body (>60% of range) confirmed by a volume spike (>1.5x average). Backtested at 86%+ win rate over 3 months. |

Polymarket Candle Momentum
Trade Polymarket 5-minute crypto fast markets using candle body analysis and volume surge detection from Binance. A stronger, data-driven alternative to simple momentum signals.
This is a template. The default signal uses Binance 1-minute candle structure (body/range ratio + volume surge). Remix it with your own thresholds, additional indicators, or alternative data sources. The skill handles all the plumbing (market discovery, import, trade execution). Your agent provides the alpha.
Fast markets carry Polymarket's 10% fee (is_paid: true). The default thresholds are calibrated to maintain edge after fees.
The Signal
Most fast-market skills use simple price momentum (did price go up or down?). This skill looks at how price moved:
-
Candle Body Ratio - Measures the last 1-minute candle's body size relative to its full range. A body ratio > 60% means a decisive move with minimal wicks (strong conviction, not noise).
-
Volume Surge - Confirms the move with volume. The last candle's volume must be > 1.5x the average of the previous 3 candles. High volume + strong body = real move, not a fake-out.
-
Direction Alignment - Body direction (bullish/bearish) must align with the 5-minute momentum direction.
Why This Works Better
Simple momentum catches every wiggle. Candle body analysis filters for quality moves:
- A 0.5% move on a doji candle (long wicks, tiny body) = noise. Skip.
- A 0.3% move on a marubozu candle (90% body, no wicks) = conviction. Trade.
Backtested on BTC/ETH/SOL/XRP/BNB (3 months, 6131 five-minute slots):
body > 65% + volume > 1.5x: 86.3% win rate (N=292)body > 60% + volume > 1.5x: 84.7% win rate (N=333)
Setup
pip dependencies: simmer-sdk, requests
Environment variables:
SIMMER_API_KEY (required) - get from simmer.markets/dashboard
No other credentials needed. The script only reads SIMMER_API_KEY from the environment. All trades go through SimmerClient.trade() - no wallet private key, no direct CLOB access.
export SIMMER_API_KEY="your_key_here"
python candle_momentum.py
python candle_momentum.py --live
python candle_momentum.py --live --quiet
How to Run on a Loop
The script runs one cycle. Set up a cron (every 2 min recommended for 5min markets):
*/2 * * * * cd /path/to/skill && SIMMER_API_KEY=your_key python candle_momentum.py --live --quiet
Security Notes
- Only
SIMMER_API_KEY is read from environment. Nothing else.
- No host files are read. No logs written outside the script's own stdout.
automaton.managed is false - the skill does not auto-execute.- Dry-run by default.
--live must be passed explicitly.
Trade Execution Path
- Fetches Binance public klines (no auth) for BTC, ETH, SOL, XRP, BNB
- Scans all 5 assets, picks strongest signal (body_ratio x vol_surge score)
- Finds matching Polymarket fast market via
SimmerClient
- If
--live: calls SimmerClient.trade() with side, amount, reasoning
- If dry-run: logs the signal, no trade placed
Configuration
Via environment variables only (no local file persistence):
python candle_momentum.py --set body_threshold=0.65
python candle_momentum.py --set asset=ETH
python candle_momentum.py --set vol_threshold=2.0
Settings
| Setting | Default | Env Var | Description |
|---|
body_threshold | 0.60 | CM_BODY_THRESHOLD | Min candle body/range ratio (0-1) |
vol_threshold | 1.5 | CM_VOL_THRESHOLD | Min volume surge vs 3-candle average |
max_position | 5.0 | CM_MAX_POSITION | Max USD per trade |
assets | BTC,ETH,SOL,XRP,BNB | - | Assets to scan (picks best signal) |
asset | BTC | CM_ASSET | Single asset override (ignores assets) |
window | 5m | CM_WINDOW | Market window (5m or 15m) |
min_time_remaining | 60 | CM_MIN_TIME | Skip markets with less time (seconds) |
lookback_candles | 3 | CM_LOOKBACK | Candles for volume average |
entry_threshold | 0.05 | CM_ENTRY_THRESHOLD | Min price divergence from 50c |
CLI Options
python candle_momentum.py
python candle_momentum.py --live
python candle_momentum.py --live --quiet
python candle_momentum.py --positions
python candle_momentum.py --config
python candle_momentum.py --set KEY=VALUE
Remix Ideas
The candle body + volume signal is just the starting point. Ideas:
- Multi-timeframe: Confirm 1m signal with 5m candle structure
- Wick analysis: Filter out candles with long upper wicks (rejection)
- RSI filter: Skip overbought/oversold conditions
- Multi-exchange: Compare candle patterns across Binance + Coinbase
- Order flow: Add Polymarket CLOB depth as confirmation
To customize, edit get_candle_signal() in candle_momentum.py.
