## Cheapest Dataset Recommendations

### For Historical Data (Using Free Credits)

**1. CME Bitcoin Futures (BTC)** ✅ RECOMMENDED
- **Why**: Single liquid crypto futures contract
- **Venue**: CME GLBX.MDP3
- **Schema**: Start with OHLCV-1m bars (cheapest), upgrade to Trades as needed
- **Cost**: ~$0.20-2.50/day depending on schema
- **Data Depth**: 12+ years of history available
- **Use Case**: Crypto futures trading, low-cost backtesting

**2. CME Micro E-mini S&P 500 (MES)** 
- **Why**: Fractional equity index exposure, lower data volume than ES
- **Schema**: OHLCV-1m or Trades
- **Cost**: ~$0.30-3.00/day depending on schema
- **Use Case**: Equity index trading, smaller contract size

**3. Single Equity (e.g., AAPL, MSFT)**
- **Why**: Test stock trading strategies with real data
- **Venue**: Nasdaq TotalView-ITCH or Databento US Equities
- **Schema**: Trades (mid-range cost)
- **Cost**: ~$1-5/day per symbol
- **Note**: Equities require subscription for live data ($199/month Standard)

**4. Crypto Exchange Data** (if available)
- Check Data Catalog for direct crypto exchange feeds (Coinbase, Kraken, etc.)
- May have different pricing than CME crypto futures
- Contact Databento for crypto venue availability

### Per-Symbol vs Flat Rate

**Historical Data**: Always per-symbol, per-GB pricing
- More symbols = higher cost (linear scaling)
- Optimize by selecting only needed symbols
- Use OHLCV bars to minimize data volume

**Live Data**: Subscription plans (post-March 2025)
- Flat monthly rate per dataset
- Unlimited symbols within dataset (subject to exchange rules)
- Better value for multi-symbol strategies

## Data Type Cost Comparison

### Schemas Ranked by Cost (Cheapest to Most Expensive)

| Schema | Description | Data Volume | Cost Tier | Best For |
|--------|-------------|-------------|-----------|----------|
| **OHLCV-1m** | 1-minute bars (O/H/L/C/V) | Lowest | $ | Backtesting, low-freq strategies |
| **OHLCV-1s** | 1-second bars | Very Low | $ | Slightly higher resolution |
| **Trades** | All executed trades | Moderate | $$ | Trade analysis, execution quality |
| **TBBO** | BBO on trade events | Moderate | $$ | Trade-triggered order book |
| **BBO-1s** | BBO snapshots (1-second) | Moderate-High | $$$ | Regular order book snapshots |
| **MBP-1** | Top-of-book updates | High | $$$ | Best bid/offer tick data |
| **MBP-10** | 10 price levels | Very High | $$$$ | Deeper order book |
| **MBO** | Full order book | Highest | $$$$$ | HFT, market microstructure |

### Cost Optimization Strategies

**1. Start with OHLCV bars ($)**
- Use 1-minute or 1-second bars for initial backtesting
- ~90% cheaper than full order book data
- Sufficient for most retail strategies

**2. Upgrade to Trades when needed ($$)**
- Get execution price/size without full book overhead
- Good for analyzing trade flow and volume
- ~50-70% cheaper than order book data

**3. Use BBO/MBP-1 for spread analysis ($$$)**
- Best bid/offer without full book depth
- Useful for spread-based strategies
- ~30-50% cheaper than full order book

**4. Reserve MBO for HFT only ($$$$)**
- Only needed for ultra-low latency strategies
- Most expensive option (5-10x cost of OHLCV)
- Databento's specialty is high-quality MBO data

## Recommendation for Limited Budget Deployment

### Phase 1: Free Testing ($0 - Use $125 Credits)

**Goal**: Validate strategy with real data before spending

1. **Sign up for Databento** (automatic $125 credit)
2. **Choose cheapest dataset**: CME Bitcoin Futures (BTC) or single equity
3. **Select cheapest schema**: OHLCV-1m bars for backtesting
4. **Download historical data**: 3-6 months (enough for initial validation)
5. **Estimated credit usage**: 
   - BTC OHLCV-1m, 90 days: ~$18 ($0.20/day)
   - 5 symbols, 30 days: ~$30 ($0.20/day/symbol)
   - Leaves $95+ credits for experimentation

**Deliverable**: Backtested strategy with real exchange data, zero cost

### Phase 2: Historical Data Expansion ($10-50/month)

**Goal**: Expand backtesting to more symbols/timeframes

1. **Add more symbols**: Scale to 5-10 symbols (~$30-60/month OHLCV)
2. **Increase data depth**: Download 1-2 years of history (~$50-100 one-time)
3. **Upgrade schema**: Move to Trades if needed (~2-5x cost increase)
4. **Total monthly cost**: $10-50 for ongoing historical data

**Cost Control Tips**:
- Only download new data (avoid re-downloading same periods)
- Use batch downloads for efficiency
- Compress and store data locally (avoid repeat API calls)
- Monitor usage in Databento portal dashboard

### Phase 3: Live Data Subscription ($179-199/month)

**Goal**: Deploy live trading strategy

1. **Choose subscription plan**: Standard ($179-199/month)
2. **Select dataset**: CME ($179) or US Equities ($199)
3. **Activate live streaming**: Real-time market data
4. **Start paper trading**: Test with live data, no real money
5. **Monitor performance**: 1-3 months before live capital

**Break-Even Analysis**:
- If trading >5 symbols continuously, subscription > usage-based
- If trading <5 symbols sporadically, usage-based might be cheaper
- ⚠️ Usage-based ending March 2025 (subscription will be only option)

### Phase 4: Multi-Dataset Scaling ($358+ per month)

**Goal**: Trade multiple asset classes

1. **Add second dataset**: OPRA options ($199) or additional venue
2. **Consider Plus tier**: Contact sales for custom pricing
3. **Bundle discounts**: Negotiate multi-dataset pricing
4. **Total cost**: $358+ per month (2 datasets at Standard tier)

# Install Databento Python client
pip install databento

# Example: Download BTC futures OHLCV bars
import databento as db

client = db.Historical('YOUR_API_KEY')

data = client.timeseries.get_range(
    dataset='GLBX.MDP3',  # CME Globex
    symbols=['BTC.FUT'],   # Bitcoin futures
    schema='ohlcv-1m',     # 1-minute bars (cheapest)
