Quick Start

git clone https://github.com/LuanSantana0/Polymarket-Trading-Bot-BTC-5-Minute-Up-Down-Dual-Leg.git
cd polymarket-trading-bot-btc-5m
npm install
cp .env.example .env
npm start

POLYMARKETPRIVATEKEY=0x...   # Your 64-character private key
PROXYWALLETADDRESS=0x...     # Optional

Requires Node.js ≥ 20.6. Ctrl+C stops the bot and prints a final balance summary. Logs go to logs.txt.

Where This Stands

The strategy this repo is built toward runs live under @powerwinner - fully on-chain, wallet 0xf3531b23b504cf0aed4ff21325232b2a2d496685, verifiable at the profile and activity feed.

That live account is hand-executed, not run from this codebase. Here's the honest gap between the two:

Closing that gap - porting the real sizing, timing, and dual-leg logic - is the active focus. Track it in Roadmap. Contributions welcome.

How It Works

Target design (from the live strategy):

• Buys both Up and Down legs every 5-minute window - no directional bet
• Heaviest fills land 60–180 seconds after the window opens
• Targets ~1,680 shares per side, built up across ~42 fills
• Edge comes from keeping the combined pair cost at or below $1.00 - execution quality, not prediction

Configuration

Defaults today (src/index.ts):

const MARKETS = ["btc", "eth", "sol", "xrp"];
const BET_USD = 10;
const ENTRYTIMEMIN = 250;   // seconds into window
const ENTRYTIMEMAX = 290;
const ENTRYPRICEMIN = 0.97;
const ENTRYPRICEMAX = 0.99;

Where it's headed:

// BTC 5m only
const TARGETSHARESPER_SIDE = 1680;
const FILLWINDOWSTART = 0;
const FILLWINDOWEND = 250;
// + dynamic scaling on both legs

Risks

| | | |---|---| | Pair cost > $1.00 | Negative EV on a perfectly hedged set - execution quality matters more than direction | | Bigger size, bigger drawdown | Larger positions mean larger potential losses | | Fees & spread | Apply on every single fill | | Sharp last-second moves | Can wipe out the cheaper leg entirely | | Live ≠ this code | The track record above is hand-executed, not a preview of what this codebase does out of the box | | Unaudited code | Actively changing - bugs can and will cost money |

Not financial advice. Use at your own risk. Never share your private key.

Roadmap

• [ ] Port dual-leg accumulation logic (sizing, timing, dynamic scaling)
• [ ] Narrow default scope to BTC 5m only
• [ ] Live CLOB order execution (past small test-size defaults)
• [ ] Configurable position sizing presets
• [ ] Docker deployment

Contributing

Issues and PRs welcome - especially toward porting the dual-leg logic above. Include a clear description and, where relevant, test results.
