Order Blocks w/Signals[bingtrading]

This script implements a custom algorithmic approach to identifying Supply and Demand zones ("Order Blocks") by utilizing a proprietary volume-weighted ranking system and a Multi-Timeframe (MTF) trend filter.

Unlike standard Order Block indicators that tend to highlight every engulfing candle, this algorithm focuses on filtering and ranking to reduce chart noise and highlight only structurally significant areas of interest.

### Technical Methodology

**1. Swing Structure & Volume Detection**
The script identifies potential reversal zones based on Swing High/Low pivot points combined with specific candle geometry (engulfing variations). However, detection is only the first step.
* **Volume Qualification:** Internally, the script calculates a volume threshold relative to the lookback period. Zones lacking sufficient volume participation during their formation are discarded immediately.

**2. Proprietary Ranking Algorithm (Array Management)**
A core feature of this script is its memory management. Standard indicators often plot a high number of boxes, cluttering the chart.
* **The Logic:** This script uses Pine Script Arrays to store identified zones in memory. It then applies a sorting algorithm to rank these zones based on "Unmitigated Strength."
* **The Output:** Only the Top 15 most relevant zones are rendered on the chart. As price mitigates (touches) a zone, the array updates, removing the mitigated zone and potentially revealing the next highest-ranked unmitigated zone.

**3. The "Replay the Past" Replay Engine**
Standard backtesting often requires activating Bar Replay mode to verify signals, adding extra steps to your analysis.
* **When enabling "Replay the Past", this script calculates a dynamic "Visible Lookback" based on the chart's right-most visible bar. This allows the internal arrays to recalculate historical states accurately when scrolling through the chart, ensuring that the visual representation matches what a trader would have seen live at that specific moment in time.

**4. MTF Trend Confluence**
To filter counter-trend signals, the script hard-codes a confluence check against Higher Timeframe (HTF) Moving Averages (4-Hour, Daily, Weekly).
* **Signal Generation:** Entry signals (Arrows) and Early Warning Signals (Dots) are only generated when price interacts with a valid, ranked Order Block **AND** aligns with the slope/position of the HTF trend structure. This serves as a "Trend Filter" to minimize false positives in strong trending environments.

### Features & Usage

* **Ranking System:** Automatically hides weak zones, displaying only the highest-ranked levels based on the algorithm's scoring.
* **3/4 Retracement Level:** Automatically plots the 75% mean threshold of the Order Block for precision interest.
* **Early Warning Signals:** Displays a dot when price enters a zone, indicating a potential setup is forming before the confirmation signal. The order block will also change color to visually aid in the highlighting of this zone.
* **Confirmation Signals:** Displays an arrow when price enters the 3/4 Retracement Level of the Order Block, signaling a potential retracement opportunity.
* **Volume Strength Metrics:** Optionally displays the underlying volume data for each block.

### Disclaimer
This script is a tool for technical analysis and market structure visualization. Past performance (even when verified via Replay mode) does not guarantee future results. Traders should use this tool to aid their own analysis, not as a standalone signal service. The ranking is based on historical data within a fixed lookback, which may vary by market volatility.
