## Quick Start

```bash
# Check current BTC price
bash scripts/dca.sh price BTCUSDT

# Project a DCA plan: $50 every 7 days, 12 buys
bash scripts/dca.sh plan 50 7 12 BTCUSDT

# Execute a $50 market buy
bash scripts/dca.sh buy BTCUSDT 50

# Check recent trades
bash scripts/dca.sh history BTCUSDT 10

# Check USDT balance
bash scripts/dca.sh balance USDT
```

## DCA Strategy Guidance

When helping users plan DCA:

1. **Ask about budget** — How much per buy, and how often?
2. **Set expectations** — DCA smooths volatility, not guaranteed profit
3. **Run projections** — Use `plan` to show scenarios before committing
4. **Recommend testnet first** — Set `BINANCE_BASE_URL=https://testnet.binance.vision`
5. **Position sizing** — Suggest 1-2% of portfolio per buy for conservative approach
6. **Never store credentials** — Always use environment variables

## Scheduling DCA Buys

For automated recurring buys, suggest setting up a cron job or OpenClaw cron:
