SuperZweig thrust

SuperZweig Thrust is a systematic breadth-momentum detector based on a modified Zweig Breadth Thrust framework. The indicator evaluates the ratio of advancing issues to total issues and applies an EMA filter to smooth short-term noise. A valid “thrust” event occurs only when the market transitions from an oversold breadth condition to an overbought breadth expansion within a maximum window of 30 trading sessions.

Core Logic

Breadth Ratio (Adv / (Adv + Dec))
The indicator pulls two user-defined tickers representing advancing and declining issues. It computes the breadth ratio and smooths it using a configurable EMA length.

Zweig Thresholds
• Oversold threshold: 0.35
• Overbought threshold: 0.64
These levels mirror the classical Zweig Breadth Thrust structure.

Trigger Conditions
• A thrust sequence begins when the EMA-smoothed breadth ratio crosses below 0.35.
• A valid buy signal (“BUY”) is generated only if the same EMA crosses above 0.64 within 30 bars of the initial oversold cross.
• If the 30-bar window expires before the overbought cross occurs, the setup is cancelled.

Output
The indicator plots:
• EMA-smoothed breadth ratio
• Static threshold lines at 0.35 and 0.64
• Visual markers for each threshold cross
• A BUY label when a confirmed SuperZweig thrust is detected

Usage
This tool identifies rare breadth-momentum acceleration regimes that historically precede persistent upside trends. It is not a standalone trading system; instead, it highlights market environments where breadth expansion has achieved the structural conditions associated with strong follow-through phases.
