TV Signal Screener

Screen markets across 6 asset classes using TradingView data. API pre-filters + pandas computed signals. YAML-driven strategies.

TradingView Screener

Screen stocks, crypto, forex, bonds, futures, and coins using TradingView's market data. Zero auth required.

Setup (Run Once)

Before first use, run the install script to create a venv and install dependencies:

bash

bash skills/tradingview-screener/install.sh

This creates .venv/ inside the skill directory with all required packages.

Execution

All scripts use the skill's own venv:

bash

skills/tradingview-screener/.venv/bin/python3 skills/tradingview-screener/scripts/<script>.py [args]

Windows:

bash

skills/tradingview-screener/.venv/Scripts/python.exe skills/tradingview-screener/scripts/<script>.py [args]

Modes

Mode	Description	Script
Screen	One-time scan with filters, columns, sort	screen.py
Signal	YAML-driven signal detection (pre-filters + computed signals)	signal-engine.py
