What is the purpose of the NVI?

The NVI is used to track 'smart money' activity by looking at price changes on days with lower than average volume.

How do I identify a bull market using these tools?

A bull market is identified when the NVI is currently higher than its 255-day moving average, which can be determined via `analyze_market_sentiment`.

Can I calculate divergence between price and volume?

Yes, use the `calculate_divergence` tool to find the relationship between price movement and the NVI or PVI indices.
