Cumulative Volume Delta with Divergence

🧠 Core Functionality:
1. Cumulative Volume Delta (CVD):
Purpose: Visualizes the difference between buying and selling pressure over time.

Mechanism:

It uses lower-timeframe volume delta data, retrieved from ta.requestVolumeDelta(), to build a candle-style visualization of the net volume movement.

Plotted candles show whether buying (up volume) or selling (down volume) was dominant within each period.

Teal candles: More buying than selling (CVD up).

Red candles: More selling than buying (CVD down).

Volume Source: Based on intrabar up/down volume approximation from lower timeframes.

🧭 Divergence Detection (New Feature):
2. Regular Bullish Divergence:
Condition:

Price makes a lower low.

CVD (lastVolume) makes a higher low.

Interpretation: Selling pressure is weakening despite price making new lows — a potential reversal signal to the upside.

Displayed As:

Green line and label "Bull" under the CVD at the divergence point.

3. Regular Bearish Divergence:
Condition:

Price makes a higher high.

CVD makes a lower high.

Interpretation: Buying pressure is fading despite price rising — a potential reversal signal to the downside.

Displayed As:

Red line and label "Bear" above the CVD at the divergence point.

🧰 User Controls:
Use custom timeframe: Overrides default volume delta resolution for finer or broader analysis.

Calculate Divergence: Turns the divergence detection on or off.

Adjustable via script inputs.

🔔 Alerts:
Two alert conditions are included:

One for bullish divergence.

One for bearish divergence.

Alerts trigger at the bar where the divergence is confirmed, not where it starts.

📈 Use Case:
This tool is ideal for traders looking to:

Spot early reversals or momentum shifts.

Combine volume analysis with price action.

Time entries or exits more accurately using volume-confirmed divergence.
