## Implementation Details

### Buffer Size Calculations

#### DefaultStrategy
```python
def get_minimum_buffer_size(self) -> Dict[str, int]:
    primary_tf = self.params.get("timeframe", "15min")
    
    # Supertrend needs 50 periods for reliable calculation
    if primary_tf == "15min":
        return {"15min": 50, "1min": 750}  # 50 * 15 = 750 minutes
    elif primary_tf == "5min":
        return {"5min": 50, "1min": 250}   # 50 * 5 = 250 minutes
    elif primary_tf == "30min":
        return {"30min": 50, "1min": 1500} # 50 * 30 = 1500 minutes
    elif primary_tf == "1h":
        return {"1h": 50, "1min": 3000}    # 50 * 60 = 3000 minutes
    else:  # 1min
        return {"1min": 50}
```

#### BBRSStrategy
```python
def get_minimum_buffer_size(self) -> Dict[str, int]:
    bb_period = self.params.get("bb_period", 20)
    rsi_period = self.params.get("rsi_period", 14)
    
    # Need max of BB and RSI periods plus warmup
    min_periods = max(bb_period, rsi_period) + 10
    return {"1min": min_periods}
```
