Before you connect
Questions about obv-calculator.
The practical details behind the request, access and result.
How can I use the OBV Calculator MCP to find trend reversals?
You can use the divergence detection capability to find instances where price is moving up but volume is moving down, which often signals a reversal.
Can I connect the OBV Calculator MCP to Claude?
Yes, you can connect this MCP to any compatible client like Claude, Cursor, or Windsurf through the Vinkius platform.
Does the OBV Calculator MCP work with real-time data?
Yes, as long as you feed the most recent price and volume data points into your agent, it will perform the calculations instantly.
What is the difference between accumulation and distribution in this MCP?
The capability classifies accumulation when volume flow supports rising prices (buying pressure) and distribution when volume flow supports falling prices (selling pressure).
Is the OBV Calculator MCP useful for crypto trading?
Absolutely. It is highly effective for identifying whether crypto price movements are driven by real volume or just low-liquidity volatility.
What is On-Balance Volume (OBV)?
OBV is a momentum indicator that uses volume flow to predict changes in stock price by analyzing whether volume is flowing into or out of a security.
How do I detect market accumulation?
You can use the classify_volume_flow capability to identify Accumulation, which is characterized by rising OBV or bullish divergence.
Can I detect price-volume divergences?
Yes, the detect_divergences capability identifies discrepancies where price movement and OBV movement do not align.
