Modular Market Brief
Create a concise but information-dense market report that is modular (can include/exclude sections) and data-backed (prices/returns/trend state when possible).
Inputs to ask for (or assume defaults)
Time window: AM (since prior close) vs PM (what changed since AM)
Regions: e.g., US, Canada, EU, Asia (user chooses)
Asset blocks: equities, rates, FX, commodities, crypto
Core tickers: indices + user’s preferred ETFs/tickers
Movers source: which exchange/market and where to get movers
Risk appetite: conservative vs aggressive framing
If the user doesn’t specify, default to a broad global dashboard with US indices, USD, oil, gold, BTC/ETH.
Report structure (recommended)
1) TL;DR (3–6 bullets) 2) Equities (by region) 3) Rates (2Y/10Y + key central bank watch) 4) FX (DXY or major pairs; local pair for user) 5) Commodities (WTI/Brent, gold, copper; add relevant) 6) Crypto (BTC/ETH + anything user cares about) 7) Top movers (top gainers/losers for a chosen exchange) 8) Patterns / trend box (BUY/SELL/WAIT labels for selected instruments) 9) One best idea (cross-asset; include invalidation)
Data guidance
Prefer programmatic price tape when available:
Use yfinance for tickers/ETFs/crypto/commodity futures (optional dependency).
If a market needs a dedicated movers list, use a web source (exchange site / finance portal) and then enrich tickers via yfinance.
Installing yfinance (recommended, but not required)
If yfinance isn’t available, the skill can still produce a narrative brief from public sources.
For reliable installs on modern Linux distros (PEP 668), prefer a venv:
python3 -m venv ~/.venvs/market-brief
~/.venvs/market-brief/bin/pip install -U pip
~/.venvs/market-brief/bin/pip install yfinance pandas numpy
Then run scripts using ~/.venvs/market-brief/bin/python.
Trend labeling (simple + explainable)
Use MA/RSI-based state labels:
BUY: close > MA20 > MA50 and RSI(14) >= 50
SELL: close < MA20 < MA50 and RSI(14) <= 50
WAIT: everything else
Always present it as a pattern (not a guarantee) and include a one-line rationale.
Bundled scripts (optional helpers)
scripts/price_tape.py: pull prices + returns + MA/RSI for a ticker list (yfinance)scripts/movers_yahoo.py: free Yahoo Finance screeners for top gainers/losers/actives (best-effort)scripts/tmx_movers.py: example movers scraper (TMX Money) you can adapt or swapscripts/render_example.md: a template you can reuse
Only run scripts if you actually need structured output; otherwise write the report directly.
Safety / finance guardrails
Don’t place trades.
Avoid certainty language. Use “pattern / bias / invalidation.”
If the user asks for explicit buy/sell instructions, provide a conceptual plan + risks.
Remind about tax/fees only when relevant.
