# Crypto Funding Rate Alert

Real-time cryptocurrency funding rate scanner that identifies profitable opportunities with negative funding rates on Binance futures markets.

## Features

- **Smart Scanning**: Monitors 40+ major cryptocurrencies for negative funding rates
- **Risk Management**: Built-in safety filters (volume, leverage limits, stop-loss)
- **Scoring System**: Combines funding rate, price trend, and trading volume
- **Signal Classification**: STRONG / MODERATE / WATCH alerts
- **No API Key Required**: Uses public Binance API endpoints
- **Historical Tracking**: Saves scan results to JSONL for analysis

## How It Works

When funding rates are negative, longs receive payments from shorts. This creates a profitable opportunity to:
1. Open a long position
2. Collect funding fees every 8 hours
3. Benefit from potential price appreciation

The scanner filters opportunities by:
- Minimum absolute funding rate (0.05%)
- Minimum 24h volume ($10M)
- Price trend analysis
- Composite scoring algorithm

## Usage

### Basic Scan

```bash
node scan.js
```

### With Custom Config

```bash
node scan.js --max-leverage 2 --min-volume 20000000 --stop-loss 0.15
```

### Automated Monitoring (Cron)

```bash
# Add to OpenClaw cron - scan every 4 hours
openclaw cron add "0 */4 * * *" "cd ~/.openclaw/workspace/skills/crypto-funding-alert && node scan.js"
```

## Configuration

Edit the `SAFE_CONFIG` object in `scan.js`:

```javascript
const SAFE_CONFIG = {
  maxLeverage: 3,          // Maximum leverage (1-5x recommended)
  maxPositionPct: 0.3,     // Max position size (30% of capital)
  stopLossPct: 0.10,       // Stop-loss percentage (10%)
  minVolume: 10000000,     // Minimum 24h volume ($10M)
  minAbsRate: 0.0005,      // Minimum funding rate (0.05%)
  maxCoins: 5,             // Max simultaneous positions
};
```

## Safety Rules

Based on real trading experience:

- **Max Leverage**: 3x (reduces liquidation risk)
- **Position Sizing**: ≤30% per coin (diversification)
- **Stop Loss**: 10% minimum (capital preservation)
- **Volume Filter**: Only liquid markets ($10M+)
- **Trend Check**: Prefer positive 24h momentum
- **No Panic Trading**: Skip during extreme volatility

## Data Storage

Scan results are saved to:
```
~/.openclaw/workspace/data/funding-monitor/scan_history.jsonl

Each line contains:
```json
{
  "timestamp": "2026-02-26T06:21:00.000Z",

}
```
