🔍 What is OBV 

On-Balance Volume (OBV) is a volume-based momentum indicator that measures buying and selling pressure.
It uses trading volume to predict potential changes in price direction.

⚙️ How OBV Works

• If price closes higher than the previous close:
  ➜ Add the day’s (or candle’s) volume to OBV.
• If price closes lower than the previous close:
  ➜ Subtract the day’s volume from OBV.
• If price closes unchanged:
  ➜ OBV stays the same.

The result is a running total that rises when money is flowing into the asset

(buying pressure) and falls when money is flowing out (selling pressure).

📊 How to Read the Chart shown

From your chart:

• OBV rises sharply from 22 Oct 16:30 to 22 Oct 19:30, meaning buying volume dominated → bullish sign.
• After that, OBV forms peaks and small dips — this shows slightly mixed volume, but still generally positive because it stays elevated.
• If price continues up while OBV also rises → confirms uptrend.
• If price stalls or falls while OBV keeps rising → could suggest accumulation (smart money buying quietly).
• If OBV starts falling while price still rises → possible bearish divergence, warning of trend weakness.
