# Binance DCA

Execute and plan Dollar-Cost Averaging strategies on Binance.

## Setup

Requires two environment variables (never hardcode these):

```bash
export BINANCE_API_KEY="your-key"
export BINANCE_SECRET_KEY="your-secret"
```

Optional: `BINANCE_BASE_URL` (defaults to `https://api.binance.com`). Use `https://testnet.binance.vision` for paper trading.

## 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
```

## Actions

### price [SYMBOL]
Get current spot price. Default: BTCUSDT.

### balance [ASSET]
Check free and locked balance for an asset. Default: USDT.

### buy SYMBOL AMOUNT [TYPE] [PRICE]
Place a buy order. AMOUNT is in quote currency (USDT).
- `MARKET` (default): Execute immediately at market price
- `LIMIT`: Requires price parameter — `buy BTCUSDT 50 LIMIT 95000`

### history [SYMBOL] [LIMIT]
Show recent trades with timestamps, side, quantity, price, and fees.

### plan [AMOUNT] [FREQ_DAYS] [NUM_BUYS] [SYMBOL]
Project a DCA plan with scenario analysis showing PnL at different price levels (-30% to +100%). Defaults: $50, every 7 days, 12 buys, BTCUSDT.

## 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:

```
# Example: buy $50 BTC every Monday at 9am UTC
0 9 * * 1 BINANCE_API_KEY=... BINANCE_SECRET_KEY=... /path/to/dca.sh buy BTCUSDT 50
```

Or via OpenClaw cron for agent-managed scheduling with alerts and confirmations.

## Error Handling

- Missing API keys → clear error message with setup instructions
- Invalid amounts → validation before API call
- API failures → descriptive error with endpoint info
- Always verify the order response status before confirming to user
