Enters mid-candle (2–12 min remaining) when ETH intracandle momentum is confirmed AND BTC is aligned. The BTC alignment gate is the secret sauce — it filters out noise trades where ETH is fighting the broader crypto trend. Fully configurable: tune momentum threshold, volume ratio, entry price window, and BTC gate to find your edge. Proven on real money. Use when you want the highest-WR crypto scalper running 24/7 on Polymarket.\"\nmetadata:\n  author: \"DjDyll\"\n  version: \"1.1.1\"\n  displayName: \"ETH Mid-Candle Scalper\"\n  difficulty: \"intermediate\"\n---\n\n# ETH Mid-Candle Scalper 🔥\n\n> **77%+ win rate. Real money. 400+ trades.**\n> ETH's 15-minute markets are even more profitable than BTC's — if you know when to enter. This strategy does. The BTC alignment gate alone filters out a third of losing trades. Battle-tested, configurable, and running 24/7.\n\n> **This is a template.** The default signal is mid-candle ETH momentum from Binance klines, filtered by BTC cross-asset alignment —\n> remix it with your own data sources, alternate confirmation signals, or additional asset gates.\n> The skill handles all the plumbing (market discovery, BTC/ETH data fetching, execution, safeguards).\n> Your tuning provides the alpha.\n\n---\n\n## What It Does\n\nETH Up/Down markets on Polymarket close every 15 minutes. This strategy waits until the candle has shown its hand — typically 2–12 minutes remaining — and only enters when:\n\n1. **ETH momentum is clear:** 5m and 3m price change both agree on direction\n2. **BTC agrees:** BTC isn't moving hard against you (cross-asset alignment check)\n3. **Volume confirms:** The move is backed by real activity, not noise\n4. **Entry price is fair:** Not too cheap (contrarian) or too expensive (overpriced)\n\n**Why BTC alignment matters:** ETH and BTC are heavily correlated. When ETH is signaling UP but BTC is dumping 0.3%, you're fighting the tide — and you'll lose. The BTC gate eliminates that class of trade entirely.\n\n**The result:** 77%+ win rate on real money. Out of the box.\n\n> ⚠️ **Important:** The defaults are calibrated to produce edge, but **you need to tune them**. Different account sizes, different risk tolerances, different times of day all affect optimal settings. The tuning guide below tells you exactly what to adjust and why. A tuned strategy beats a default strategy every time.\n\n---\n\n## Setup\n\n### 1. Install\n\n```bash\nclawhub install polymarket-eth-midcandle\n```\n\nSet your API key:\n```bash\nexport SIMMER_API_KEY=sk_live_your_key_here\n```\n\n### 2. Configure your agent ID\n\n```bash\npython eth_midcandle.py --set poly_agent_id=your_agent_id_here\n```\n\nFind your agent ID at **simmer.markets/dashboard → Agents**.\n\n### 3. Paper trade first\n\n```bash\npython eth_midcandle.py\n```\n\nYou'll see `[PAPER MODE]` — no real money. Run this for at least a day to understand when it fires and why.\n\n### 4. Go live\n\n```bash\npython eth_midcandle.py --live\n```\n\n### 5. Set up cron\n\n```bash\ncrontab -e\n```\n\nAdd:\n```\n3,8,13,18,23,28,33,38,43,48,53,58 * * * * cd /path/to/skill && python eth_midcandle.py --live >> /var/log/eth-midcandle.log 2>&1\n```\n\nRuns every 5 minutes, staggered for best execution timing.\n\n---\n\n## Configuration\n\n```bash\npython eth_midcandle.py --config\npython eth_midcandle.py --set momentum_threshold=0.0012\n```\n\n| Parameter | Env Var | Default | Description |\n|-----------|---------|---------|-------------|\n| `poly_agent_id` | `SIMMER_ETHMC_AGENT_ID` | — | Your Polymarket agent ID (required) |\n| `bet_size` | `SIMMER_ETHMC_BET_SIZE` | `5.0` | USDC per trade |\n| `momentum_threshold` | `SIMMER_ETHMC_THRESHOLD` | `0.0012` | Min 5m ETH price change (0.12%) |\n| `btc_gate_threshold` | `SIMMER_ETHMC_BTC_GATE` | `0.0015` | BTC move required to veto trade (0.15%) |\n| `min_volume_ratio` | `SIMMER_ETHMC_VOL_RATIO` | `1.1` | Volume vs 2h avg (0 = disabled) |\n| `min_entry_price` | `SIMMER_ETHMC_MIN_ENTRY` | `0.45` | Min entry price per side |\n| `max_entry_price` | `SIMMER_ETHMC_MAX_ENTRY` | `0.65` | Max entry price per side |\n| `enable_1m_confirm` | `SIMMER_ETHMC_1M_CONFIRM` | `false` | Require 1m candle to confirm direction |\n| `skip_hours` | `SIMMER_ETHMC_SKIP_HOURS` | `13,17` | UTC hours to skip (historically poor WR) |\n| `discord_webhook` | `SIMMER_ETHMC_WEBHOOK` | `\"\"` | Discord alert webhook (optional) |\n| `max_position_usd` | `SIMMER_ETHMC_MAX_POS` | `50.0` | Max USDC per trade when using `--smart-sizing` |\n| `sizing_pct` | `SIMMER_ETHMC_SIZING_PCT` | `0.03` | Portfolio % per trade when using `--smart-sizing` (3%) |\n\n> ⚠️ **SKIP HOURS — READ THIS BEFORE TRADING**\n>\n> By default, the strategy **skips hour 13 UTC (9am ET) and hour 17 UTC (1pm ET)**. These hours have a historically poor ETH midcandle win rate — **sub-45%**, meaning you lose money on average.\n>\n> - **Hour 13 UTC (9am ET):** NY open volatility makes ETH momentum signals unreliable. Sharp reversals are common.\n> - **Hour 17 UTC (1pm ET):** Post-lunch chop. Random, low-conviction price action that fakes out momentum signals.\n>\n> **Do NOT remove these skip hours** unless you have your own data (50+ trades minimum) showing profitability during those hours. The default skip list exists because real money was lost learning this lesson.\n>\n> To modify: `python eth_midcandle.py --set skip_hours=13,17,21` (add hours) or `--set skip_hours=` (disable — not recommended).\n\n---\n\n## Tuning Guide\n\n> The defaults work. Tuning makes them work better for you specifically.\n\n### Momentum threshold (`momentum_threshold`)\nHow much ETH must move in 5 minutes before you enter.\n\n- **Lower (0.0008–0.0012):** More trades. Good when ETH is in a clear trend.\n- **Higher (0.0018–0.0025):** Only trade strong moves. Better in choppy or sideways conditions.\n- **Start at default (0.0012)** and only adjust after 50+ paper trades.\n\n### BTC alignment gate (`btc_gate_threshold`)\nThe BTC 5m move that triggers a veto.\n\n- **Lower (0.0010):** Stricter BTC filter — vetoes more trades when BTC wiggles\n- **Higher (0.0020–0.0025):** Only veto when BTC is moving hard — allows more ETH-independent trades\n- **Default (0.0015)** is the sweet spot: vetoes divergent trades without over-filtering\n\n### Volume ratio (`min_volume_ratio`)\nFilters low-volume moves that tend to reverse.\n\n- **0 (disabled):** Pure momentum, no volume filter\n- **1.1 (default):** Trade when volume is 10% above the 2-hour average\n- **1.5+:** High-conviction only. Fewer trades, stronger confirmation\n\n### Entry price window\n- **Too cheap (<0.40):** You're fading the crowd — usually wrong\n- **Too expensive (>0.70):** Limited upside relative to risk\n- **Default 0.45–0.65:** Balanced. You can tighten to 0.50–0.60 for higher precision at cost of volume\n\n### 1m confirmation (`enable_1m_confirm`) — **OFF by default**\nAdds a final gate: the last 1-minute candle must agree with your trade direction.\n\n- **Disabled (default):** More trades, baseline win rate\n- **Enabled:** Meaningful reduction in false signals — especially useful during London/NY open volatility\n\n> 💡 **Tip:** Enable `1m_confirm` after your first week of paper trading. Most users see their win rate tick up 2–4% with it on.\n\n### Skip hours (`skip_hours`)\nUTC hours with historically poor ETH midcandle win rate. Defaults are `13,17`.\n\n- Hour 13 UTC (9am ET): NY open volatility makes momentum signals unreliable\n- Hour 17 UTC (1pm ET): Post-lunch chop, random price action\n- Only remove these if you have enough personal data showing otherwise\n\n---\n\n## Commands\n\n```bash\npython eth_midcandle.py               # Paper trade\npython eth_midcandle.py --live        # Real trades\npython eth_midcandle.py --positions   # Open positions\npython eth_midcandle.py --config      # Current config\npython eth_midcandle.py --smart-sizing  # Size by portfolio %\npython eth_midcandle.py --no-safeguards  # Skip flip-flop/slippage checks\npython eth_midcandle.py --set momentum_threshold=0.0010\n```\n\n---\n\n## Example Output\n\n```\n============================================================\n🔴 LIVE: ETH Mid-Candle Scalper — 2026-03-15 22:18 UTC\n============================================================\n⏰ Candle :15 | 7 min remaining | ✅ In window\n📊 Volume: 1.34x ✅\n📈 ETH Momentum: up | 5m: +0.1543% | 3m: +0.0821%\n   1m: up (+0.0412%) — gate disabled\n₿  BTC check: +0.0923% — ✅ aligned\n📋 Market: Will ETH go up or down — March 15, 10:15-10:30PM ET?\n💲 Entry price: 0.531 (side=yes)\n\n🚀 Placing YES $5.00 — Mid-candle up (7m left): 5m=+0.1543% 3m=+0.0821% vol=1.34x BTC=+0.0923%\n✅ Filled: 9.4 YES shares for $5.00\n```\n\n---\n\n## The BTC Gate — Explained\n\nETH and BTC move together ~80% of the time. When they diverge:\n- ETH signaling UP while BTC dropping hard → ETH is wrong, BTC leads\n- ETH signaling DOWN while BTC pumping hard → same problem\n\nThe BTC gate catches this. Before entering, the strategy checks if BTC moved more than `btc_gate_threshold` in the opposite direction. If it did, the trade is skipped.\n\nThis single filter is responsible for a significant portion of the win rate improvement over naive ETH momentum strategies. Don't disable it without data.\n\n---\n\n## Remix Ideas\n\n- **Funding rate confirmation:** Only trade ETH UP when perpetual funding is positive (longs paying)\n- **ETH/BTC ratio:** Add a ratio signal — trade ETH when it's outperforming BTC on the ratio\n- **Options skew:** Skip trades when ETH options put/call ratio is elevated\n- **On-chain:** Add net exchange flows as a confirmation signal for larger size\n\n---\n\n## Troubleshooting\n\n**Firing less than expected?**\n- Lower `momentum_threshold` to 0.0010\n- Check skip hours — maybe you're running during 13h or 17h UTC\n- Verify your cron is running: `tail -f /var/log/eth-midcandle.log`\n\n**Losing more than expected?**\n- Enable `enable_1m_confirm` — adds a key anti-noise filter\n- Raise `momentum_threshold` to 0.0018\n- Check that `btc_gate_threshold` is set — it should NOT be 0\n\n**\"BTC check failed\"?**\n- Binance API timeout — the strategy falls through to neutral (still trades)\n- If happening regularly, your server may have connectivity issues to Binance\n\n**Win rate below 65%?**\n- You're likely trading the wrong hours — check if hour 13 or 17 UTC is in your logs\n- Try enabling `enable_1m_confirm`\n- Run paper mode for a week before re-evaluating\n","tags":{"latest":"1.1.1"},"stats":{"comments":0,"downloads":801,"installsAllTime":30,"installsCurrent":0,"stars":0,"versions":5},"createdAt":1773616468761,"updatedAt":1779078260864},"latestVersion":{"version":"1.1.1","createdAt":1774038001689,"changelog":"Add signal_data to trade calls (incl.
