Multi-timeframe sentiment analysis

Market Risk indicator
The extension also calculates a market instability score based on:

• distance from neutral sentiment  
• disagreement between timeframes  
• short-term sentiment impulses  

This creates a simple risk indicator from 0 to 100 showing how unstable the market currently is.

Risk levels:
LOW – calm market  
MEDIUM – unstable conditions  
HIGH – turbulent market  
EXTREME – chaotic sentiment environment

Market structure view
The Details tab provides deeper insight into market conditions:

• Market Tilt – average sentiment across timeframes  
• TF Spread – disagreement between timeframes  
• Extremes – distance from neutral sentiment  

How it works

The extension detects the trading pair from the active tab on supported exchanges and automatically loads the sentiment analysis for that pair.

The interface updates automatically when you change trading pairs or refresh the chart.

API key (optional)

Users can optionally connect an API key to unlock higher request limits and premium features.

No API key is required for the basic functionality.

Privacy and security

SentiPulse does not collect personal data.

The extension only reads the URL of the active tab on supported exchanges in order to detect the trading pair (for example BTCUSDT).

All API keys are stored locally in the browser using Chrome storage and are never shared with third parties.

SentiPulse is designed as a lightweight trading companion for market awareness and sentiment analysis.
