# Bybit Futures Trading System

Complete trading infrastructure for Bybit USDT perpetual futures contracts.

## Quick Start

1. Install dependencies: `pip install ccxt websockets numpy requests`
2. Copy `scripts/config_template.py` → `config.py`, fill in API keys
3. Run paper trading: `python scripts/paper_trading_ws.py`
4. When validated, switch to live: `python scripts/live_trading.py`

## Architecture

```
config.py          ← API keys + risk parameters
risk_manager.py    ← Position sizing, daily loss limits, max positions
paper_trading_ws.py ← WebSocket real-time paper trading
live_trading.py    ← Live execution (same logic, real orders)
backtest.py        ← Historical backtesting engine
```

## Risk Management

All trades enforced by `risk_manager.py`:
- **Max position**: configurable % of capital per trade (default 20%)
- **Max leverage**: configurable (default 5x)
- **Stop loss**: automatic per-trade (default 3%)
- **Take profit**: automatic per-trade (default 6%, 2:1 R/R)
- **Daily loss limit**: halt trading after X% daily drawdown (default 10%)
- **Max concurrent positions**: configurable (default 3)

## Included Strategies

### EMA Crossover (ETH)
- EMA(12) crosses above EMA(26) → long
- EMA(12) crosses below EMA(26) → short
- Best on: ETH/USDT 1h timeframe

### RSI Mean Reversion (SOL, HYPE, PEPE)
- RSI(14) crosses up from below 30 → long
- RSI(14) crosses down from above 70 → short
- Best on: SOL, HYPE (73% WR), 1000PEPE (53% WR) 1h timeframe
- Backtested: HYPE +$339, PEPE +$210 on 90-day 1h data

### Custom Strategy Template
See `references/custom_strategy.md` for adding your own signals.

## WebSocket Real-Time Engine

The paper/live trading engine uses Bybit's WebSocket v5 API:
- **Ticker subscription**: millisecond-level price updates for SL/TP
- **Kline subscription**: signal calculation on candle close only
- **Auto-reconnect**: 5s retry on disconnect
- **State persistence**: saves every 5 minutes to JSON
