Simple Volume Indicator

Volume is an important indicator in technical analysis because it is used to measure the relative significance of a market move.
The higher the volume during a price move, the more significant the move and the lower the volume during a price move, the less significant the move.

here i made some changes using Significant volume which helps to see the Price moment

Black = Unconsumed Selling
Blue = Exceptional Buying Strength
Yellow = Demand Strength

The Supply–Demand Battle
Think of it like this:

Black bar = supply waiting to be absorbed.

Blue = demand stepping in to absorb supply.

Yellow = Strength of move

If Black dominate without follow-up blue/yellow, price struggles.

If blue/yelow appear after Black, it signals buyers are winning.
