--- name: tvscreener description: Query TradingView screener data for HK, A-share, A-share ETF, and US symbols with deepentropy/tvscreener. Use for stock lookup, technical indicators (price/change/RSI/MACD/volume), symbol filtering, and custom field/filter-based market queries. ---

tvscreener

Use this skill for market queries with simple scripts first, then native Python when needed.

Install

python3 -m pip install -U tvscreener

Python must be >=3.10.

Quick commands (run from skill root)

> Use Python 3.10+ in your preferred environment (venv/pyenv/system Python).

# Preset single-symbol output (recommended)
python3 scripts/query_symbol.py --symbol HKEX:700 --market HONGKONG

# Custom query (fields + filters)
bash scripts/run_query.sh \
  --market CHINA \
  --symbol SHSE:600519 \
  --fields 'NAME,PRICE,CHANGE_PERCENT,VOLUME,RELATIVE_STRENGTH_INDEX_14,MACD_LEVEL_12_26,MACD_SIGNAL_12_26,MACD_HIST,SIMPLE_MOVING_AVERAGE_20,SIMPLE_MOVING_AVERAGE_50,SIMPLE_MOVING_AVERAGE_200,EXPONENTIAL_MOVING_AVERAGE_20,EXPONENTIAL_MOVING_AVERAGE_50,EXPONENTIAL_MOVING_AVERAGE_200,BOLLINGER_UPPER_BAND_20,BOLLINGER_LOWER_BAND_20,STOCHASTIC_PERCENTK_14_3_3,STOCHASTIC_PERCENTD_14_3_3,AVERAGE_TRUE_RANGE_14,MOVING_AVERAGES_RATING' \
  --filter 'NAME=600519'

# Field discovery
python3 scripts/discover_fields.py --keyword macd --limit 20

Shell quoting notes

• Wrap --fields and --filter in single quotes.
• If you use interval syntax like FIELD|60, quoting is mandatory to avoid shell pipe parsing.

Query rules

• Core technical set (recommended): PRICE, CHANGE_PERCENT, VOLUME, RELATIVE_STRENGTH_INDEX_14, MACD_LEVEL_12_26, MACD_SIGNAL_12_26, MACD_HIST, SIMPLE_MOVING_AVERAGE_20/50/200, EXPONENTIAL_MOVING_AVERAGE_20/50/200, BOLLINGER_UPPER_BAND_20, BOLLINGER_LOWER_BAND_20, STOCHASTIC_PERCENTK_14_3_3, STOCHASTIC_PERCENTD_14_3_3, AVERAGE_TRUE_RANGE_14, MOVING_AVERAGES_RATING
• Interval fields syntax: FIELD|60 / FIELD|240 (example: RELATIVE_STRENGTH_INDEX_14|60)

- Current caveat: interval fields may fail in scripts/custom_query.py with FieldWithInterval attribute errors in some tvscreener versions. - Workaround: run without interval fields, or use scripts/query_symbol.py for stable single-symbol technical snapshots.

• Filters: =, !=, >, <, >=, <=

Troubleshooting

• ImportError: cannot import name 'Market' from 'tvscreener'

- Usually caused by mismatched Python/site-packages or multiple Python environments. - Fix: ensure commands and installation use the same Python (3.10+), then reinstall: - python3 -m pip install -U tvscreener

• zsh: command not found: 60,...

- Cause: unquoted FIELD|60 interpreted as shell pipes. - Fix: single-quote the full --fields string.

• API details:

If scripts are insufficient, read references and write direct Python using tvscreener native API.
