Vwap Delta

This script calculates the delta between the close price and the VWAP (Volume Weighted Average Price) over a custom-defined period (currently only "Day" is supported).

⚙️ How it works

User Inputs:

period: Only "Day" is supported (input as string).

filter: A threshold (default 3000) to color the background if the VWAP delta exceeds it.

Period Detection:

Uses dayofweek to detect when a new trading day begins.

VWAP Calculation:

VWAP is calculated using cumulative values of (hlc3 * volume) and volume, reset each new day.

Delta Logic:

Computes vwapDelta = close - vwap

Highlights background in gray if vwapDelta exceeds the filter (positive or negative).

Visualization:

Plots the delta as a histogram, useful for visualizing deviations from VWAP.

✅ Strengths:

Straightforward day-based VWAP delta logic.

Clean visual output with background highlighting for large deltas.

⚠️ Suggestions:

Currently, only "Day" is supported. Add more period logic if needed (e.g., "Week", "Month").

Variable sumSrcSrcVol is unused; either remove or complete its logic for VWAP standard deviation.

The filter value of 3000 seems high unless you're working with large-priced assets. Consider scaling it relative to price if needed.
