## What it does

The skill reads a request in natural language and maps it to FinViz filter codes. English and Japanese input both work. It then builds the URL with the chosen view type and sort order, and the browser opens the page.

Inside are a filter reference at `references/finviz_screener_filters.md` and a script at `scripts/open_finviz_screener.py`. The script takes `--filters`, `--themes`, `--subthemes`, `--view`, `--order` and `--url-only`. At least one of the first three is required, or the run fails. The `theme_*` and `subtheme_*` tokens are rejected in `--filters`; those have their own flags.

Before running, the skill prints a table of the chosen filters and asks you to confirm or adjust. The public screener needs no API key. FinViz Elite mode is detected from the `$FINVIZ_API_KEY` environment variable, or forced with `--elite`. For ranges such as a 3-8% dividend yield, use one token like `fa_div_3to8` instead of two separate filters.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add tradermonty/claude-trading-skills --skill finviz-screener -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/finviz-screener/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/finviz-screener/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add tradermonty/claude-trading-skills --skill finviz-screener -a codex
```

2. **Manually: put the files in place**

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add tradermonty/claude-trading-skills --skill finviz-screener -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/finviz-screener/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

## When to use it
- build a FinViz screener link from described criteria
- find undervalued large caps near 52-week lows
- screen for stocks with quarter-over-quarter sales and earnings growth
- show tickers with insider buying
- filter a sector or industry together with dividend yield

## Example prompts
- Find oversold large caps near 52-week lows
- Show me FinViz stocks with dividend yield above 3% and ROE above 15%
- Build a screener for the artificialintelligence theme with the cap_midover filter

name: finviz-screener
description: Build and open FinViz screener URLs from natural language requests. Use when user wants to screen stocks, find stocks matching criteria, filter by fundamentals or technicals, or asks to open FinViz with specific conditions. Supports both Japanese and English input (e.g., "高配当で成長している小型株を探したい", "Find oversold large caps with high ROE").

# FinViz Screener

## Overview

Translate natural-language stock screening requests into FinViz screener filter codes, build the URL, and open it in Chrome. No API key required for public screener; FINVIZ Elite is auto-detected from `$FINVIZ_API_KEY` for enhanced functionality.

**Key Features:**
- Natural language → filter code mapping (Japanese + English)
- URL construction with view type and sort order selection
- Elite/Public auto-detection (environment variable or explicit flag)
- Chrome-first browser opening with OS-appropriate fallbacks
- Strict filter validation to prevent URL injection

## When to Use This Skill

**Explicit Triggers:**
- "高配当で成長している小型株を探したい"
- "Find oversold large caps near 52-week lows"
- "テクノロジーセクターの割安株をスクリーニングしたい"
- "Screen for stocks with insider buying"
- "FinVizでブレイクアウト候補を表示して"
- "Show me high-growth small caps on FinViz"
- "配当利回り5%以上でROE15%以上の銘柄を探して"

**Implicit Triggers:**
- User describes stock screening criteria using fundamental or technical terms
- User mentions FinViz screener or stock filtering
- User asks to find stocks matching specific financial characteristics

**When NOT to Use:**
- Deep fundamental analysis of a specific stock (use us-stock-analysis)
- Portfolio review with holdings (use portfolio-manager)
- Chart pattern analysis on images (use technical-analyst)
- Earnings-based screening (use earnings-trade-analyzer or pead-screener)

---

## Workflow

### Step 1: Load Filter Reference

Read the filter knowledge base:

```bash
cat references/finviz_screener_filters.md
```

### Step 2: Interpret User Request

Map the user's natural-language request to FinViz filter codes. Use the Common Concept Mapping table below for quick translation, and reference the full filter list for precise code selection.

**Note:** For range criteria (e.g., "dividend 3-8%", "P/E between 10 and 20"), use the `{from}to{to}` range syntax as a single filter token (e.g., `fa_div_3to8`, `fa_pe_10to20`) instead of combining separate `_o` and `_u` filters.

**Common Concept Mapping:**
