CISD Engine & FVG/iFVG [Herman]

CISD Engine & FVG/iFVG [HERMAN]

Purpose:

The CISD Engine & FVG/iFVG [HERMAN] is designed to help traders identify potential shift points in market structure and delivery dynamics, as well as price imbalances (FVG/iFVG) that often act as magnets or reaction zones.
This tool is meant as confluence—an additional layer of confirmation alongside any trade entry model you prefer (e.g. ICT-style entries, breakouts, reversals).

How It Works:

1️⃣ CISD Engine (Change in State of Delivery)
The CISD Engine identifies shifts in the "State of Delivery"—that is, a confirmed change from bearish to bullish order flow or vice versa.

It uses a pullback-filtered breakout logic:
-Detects valid pullback candles (based on body % filter to avoid weak signals like dojis).
-Confirms the breakout in the opposite direction with strong displacement.
-Plots CISD levels (lines on chart) showing the price where the change of state was confirmed.
-Labels them as +CISD (bullish) or -CISD (bearish).
-These levels act as potential support/resistance areas and can be used to anticipate reaction zones or trend shifts.

Customization:

-Choose bullish and bearish line colors.
-Adjust line style and thickness.
-Configure how many bars forward lines are extended.
-Optionally keep or discard older CISD levels to reduce clutter.

2️⃣ FVG and iFVG Detection
What is FVG?
A Fair Value Gap (FVG) is a price imbalance between three candles where the middle candle’s high or low leaves a gap against the neighboring candles. It's considered an area of inefficiency that price often seeks to revisit.

What is iFVG?
An inverted Fair Value Gap (iFVG) is a confirmation of an FVG that has been traded back through and invalidated. This level can act as a stronger confluence for reversals.

Logic in this Indicator:

-Automatically detects and plots FVG zones (boxes on chart).
-Waits for price to invalidate these zones (e.g. by closing through them) to confirm them as iFVGs.
-Allows setting minimum size filters to avoid noise.
-Color-coded bullish/bearish FVG and iFVG zones for easy reading.

Customization:

-Toggle FVG and iFVG detection on/off.
-Adjust max number of displayed FVG/iFVG zones.
-Configure box colors, borders, and labels.
-Control extension and appearance of boxes.

Main Features
✅ CISD Engine with custom pullback filtering to avoid weak setups.
✅ Dynamic detection of bullish/bearish order flow shifts with plotted levels.
✅ Automatic FVG detection (imbalance zones) as magnets or reaction targets.
✅ iFVG detection (invalidation of prior imbalance) for extra confirmation.
✅ Fully customizable visuals: colors, opacity, number of boxes, borders, labels.
✅ Designed to be used as confluence with any entry/exit strategy.

Suggested Use:

-Combine CISD levels with your OHLC Statistical Map Indicator
-Watch for price to react to FVG or iFVG levels.
-Use as an extra filter for scalping or swing setups.

This tool is ideal for traders who want structured market reading, clear levels, and mechanical confirmation of delivery shifts and imbalance zones without subjective drawing.
