Cumulative Volume Delta [Pro] v1.0

Volume Delta is the X-Ray machine for a candle.While a standard volume bar tells you how much activity happened, it keeps the participants anonymous.

It doesn't tell you if the buyers were in control or if the sellers were dumping.Volume Delta peels back the skin of the candle to reveal the Aggressive Intent.

1The Mechanics (How it Works)Every trade requires a Buyer and a Seller. However, for price to move, one side must be Aggressive (using Market Orders) and the other side must be Passive (using Limit Orders).Ask Volume (Buying):
Traders hitting the "Buy" button at market price. They are impatient and demand liquidity.Bid Volume (Selling): Traders hitting the "Sell" button at market price. They are dumping inventory.

How to Read It (The Cantillon Lens)1. Positive Delta (+)What it means: Aggressive buyers overwhelmed sellers.

2The Narrative: "First Receivers" or eager retail traders are lifting the offer. Demand is real.2. Negative Delta (-)

What it means: Aggressive sellers overwhelmed buyers.
The Narrative: Someone is offloading inventory or shorting aggressively. Supply is dominant.

3. The Anomaly (The "Trap")
This is the most powerful signal.Example: Price makes a massive Green Candle (Price UP), but the Delta is Negative.Translation: This is a "Limit Order Absoption." Retail traders are aggressively buying (Market Buys), but a massive Institutional Seller is sitting there with a Limit Sell wall absorbing all of it.Result: The move is fake.
Price is about to reverse.Why It Matters In the Cantillon Terminal, we use Delta to distinguish between a Trend and a Trap.
Trend: Price is moving UP, and Delta is consistently Positive (Aggression matches Price).

Trap: Price is moving UP, but Delta is Flat or Negative (Price is floating up on thin air, waiting to be swatted down).
