Basic Pivot-Based S/R with Stopping Lines

Basic Pivot-Based S/R with Intrabar Pressure Analysis

Overview:

This indicator identifies potential support and resistance levels based on a combination of traditional pivot point analysis and a unique intrabar volume pressure assessment. It goes beyond simply identifying pivot highs and lows; it qualifies these pivots by examining the underlying buying and selling pressure within the candles that form the pivot. This approach aims to identify stronger, more reliable support and resistance levels than those based on price action alone.

Core Concepts and Calculations:

Pivot Points: The indicator uses the standard ta.pivothigh() and ta.pivotlow() functions to detect pivot highs and lows. The user can choose whether to use the candle wicks ("Wick" mode) or the candle bodies ("Body" mode) for pivot detection. The leftBars and rightBars parameters control the number of bars on either side of the pivot used in the calculation.

Intrabar Volume Pressure: This is the indicator's key differentiator. It analyzes the volume distribution within each candle by accessing data from a lower timeframe (specified by the user, defaulting to 1-second data). For each candle:

Up Volume: The total volume associated with price increases within the candle is calculated (on the lower timeframe). This uses the volume multiplied by how much the price has moved up.
Down Volume: The total volume associated with price decreases within the candle is calculated (on the lower timeframe). This uses the volume multiplied by how much the price has moved down.
These up and down volumes are then summed across all lower timeframe candles.
Pressure Imbalance at Pivots: The indicator then checks for a specific condition at each identified pivot point

These lines are dynamic. They continue to extend to the right as long as the price does not decisively cross them.
A support line (green) stops extending if the price closes below the line.
A resistance line (red) stops extending if the price closes above the line. *This behavior reflects the idea that a support/resistance level is "validated" as long as the price respects it and "invalidated" once the price breaks through.
Interpretation and Usage:

The core idea is that a pivot point where the internal volume pressure contradicts the external price action (e.g., a green candle with more selling pressure) is a stronger and more reliable support or resistance level. This suggests that there's hidden buying or selling interest at that level, which may not be immediately obvious from the candlestick pattern alone.

Green Lines (Support): Indicate potential areas where buyers are likely to step in, even if the price is currently declining. These are levels where buying pressure was surprisingly strong despite a red candle forming at a pivot low.
Red Lines (Resistance): Indicate potential areas where sellers are likely to emerge, even if the price is currently rising. These are levels where selling pressure was surprisingly strong despite a green candle forming at a pivot high.
Line Extensions: The length of the line indicates how long the support or resistance level has held. Longer lines suggest stronger, more established levels.
Line Breaks: When a line stops extending, it indicates that the support or resistance level has been broken. This can be a signal of a potential trend change or a breakout.
Advantages:

Combines Price and Volume: Integrates both price action (pivots) and volume information (intrabar pressure) for a more comprehensive analysis.
Identifies "Hidden" S/R: Highlights support and resistance levels that might be missed by traditional pivot analysis.
Dynamic Lines: The lines adapt to market conditions, extending only as long as the S/R level remains valid.
Simple Visualization: Uses clear, horizontal lines for easy identification of potential support and resistance.
High Resolution Data: Uses data from a user selectable lower timeframe for better accuracy.
Limitations:

Lower Timeframe Data Dependency: The accuracy of the intrabar pressure analysis depends on the availability and quality of lower timeframe data.
Parameter Sensitivity: The indicator's performance is influenced by the pivot detection parameters (leftBars, rightBars) and the chosen lowerTimeframe.
Not a Standalone System: This indicator, like all indicators, should be used in conjunction with other forms of analysis and as part of a complete trading strategy.
In summary, this indicator offers a refined approach to identifying support and resistance levels by combining classic pivot point analysis with a detailed examination of the volume dynamics within the candles that form those pivots. This provides a more nuanced view of buying and selling pressure, potentially leading to the identification of stronger and more reliable S/R levels.
