RTH Volume Candle Delta

Overview
This indicator is designed specifically for RTH (Regular Trading Hours) intraday traders who scalp the E-mini S&P 500 (ES), Nasdaq (NQ), and other high-liquidity futures. It solves a major flaw in time-based charts: the inability to see the "Speed of the Tape." By using a unique Transparency Heatmap, it simulates MotiveWave-style Constant Volume Bars while keeping your candles fixed to the time-based X-axis to maintain alignment with indicators like VWAP and EMAs.

The Power of RTH (Regular Trading Hours)
This script is optimized for the high-liquidity environment of the US Regular Session.
During RTH: The volume distribution is statistically significant, allowing the script to accurately identify institutional "sweeps."
During ETH (Overnight): Volume is often too thin for reliable delta analysis. I have included a "Hide Overnight" toggle to keep your chart clean and focused on the liquidity that matters.

Core Logic 1: Volume Partitioning (The Heatmap)
The script partitions volume into two visual states based on your target (Default: 1000V):
Normal Volume (< Target): These candles are dimmed (High Transparency). They represent background noise where the volume target has not yet been reached within that time slice.
Burst Volume (> Target): These candles become solid (Opaque). If a single 15s bar exceeds 1000V, it highlights a Velocity Peak—this is where institutional "Big Money" is actively consuming liquidity.

Core Logic 2: Effort-Based Delta (1s Precision)This is the "engine" of the script. Rather than using simple Close-Open delta, it fetches 1-second sub-bar data (the highest precision available without tick data) and applies an Effort vs. Result formula:$DELTA = Volume \times \frac{(Close - Low) - (High - Close)}{High - Low}$$Buyer Effort: $(Close - Low)$ — How effectively buyers lifted price from the floor before the close.Seller Effort: $(High - Close)$ — How effectively sellers pushed price down from the ceiling.Adaptive Light-Up: The candle "Lights Up" (White/Yellow) only when the Delta is 1.5x greater than the MA 20 of recent deltas. This filters out standard two-way trade and highlights aggressive initiative.

How to Trade with this Indicator
Spotting Absorption: If you see a Solid (Burst) candle with a small body and "Normal" color, a limit order "Wall" is likely absorbing the market orders.

Confirming the Drive: A Solid White/Yellow candle at a key level (VWAP, PDH, or Opening Range) is a high-probability signal that aggressive money is driving the breakout.

Multiplier Labels: The labels provide an "x Multiplier" (e.g., x4.2), telling you exactly how many 1000V rotations occurred within that single time-bar.

Final Recommendations for Users
ES (S&P 500): 1000V is the standard. On a 1m chart, set it to 4000V.
NQ (Nasdaq): 400V - 500V is recommended due to thinner liquidity.
Setup: For the best experience, hide the default TradingView candle bodies in your chart settings.
