Market Monitor for Claude, Cursor, ChatGPT & agents

Proactive watch loop — the heart of TradeLoop's 'set it and forget it' monitoring

What it does

Proactive watch loop — the heart of TradeLoop's 'set it and forget it' monitoring. Set rules per symbol once (watch_add); a Claude loop calls check() every few minutes and gets back ONLY the alerts that newly fired (edge-triggered against saved state, so it never spams you while a condition stays true). Each alert is a plain-English message with sourced numbers and a `source` field naming the feed that produced them. Rule catalog — bar rules: rsi_above/rsi_below {value}, price_above/price_below {value, laddered}, pct_change_above {value, dir:up|down|abs}, sma_cross {ref:sma20|sma50|sma200, dir:above|below}, macd_cross {dir:bullish|bearish}, bollinger_break {band:upper|lower}, rvol_above {value, stocks only}; event rules (key-free, no bars needed): earnings_within_days {value:days} fires once when the next earnings date enters the window (Yahoo calendar, 24h cache), new_filing {form?: e.g. 8-K|10-Q|4} fires once per new SEC EDGAR filing with items/date/URL (first check arms silently), portfolio_weight_above {value:pct} fires when a position crosses above value% of portfolio value (attach to a symbol or to '*' for every position). Data: crypto key-free (CoinGecko); stocks prefer Polygon and FALL BACK to Yahoo's key-free chart API when Polygon fails (auth/5xx/no bars) — ^indices (^VIX) and international tickers (0700.HK) always use Yahoo. watch_add validates every rule (unknown types/missing params are rejected with the fix spelled out).

The Market Monitor skill is one of 40+ pre-wired TradeLoop integrations that any MCP-compatible client — Claude Desktop, Claude Code, Cursor, Windsurf, Codex CLI, and ChatGPT desktop — can call out of the box. You don't configure MCP servers or copy API keys into a JSON file; the TradeLoop daemon discovers the skill at startup and exposes its tools to whichever AI client is running.

Sample prompts

Once TradeLoop is installed and Market Monitor is connected, ask your agent something like:

• “Check from Market Monitor.”
• “Watch Add add from Market Monitor.”
• “Watch List list from Market Monitor.”

Tools available (5)

• monitor__check

  Evaluate every watched rule against fresh data and return ONLY newly-fired alerts (edge-triggered vs saved state — safe to call on a 5-min loop without spamming). Each alert carries message/price/asof plus `source` (Polygon | Yahoo | CoinGecko | SEC EDGAR) so you always know which feed produced it. errors[] is deduped

• monitor__watch_add

  Add or update the rules for one symbol in the persisted watchlist. Every rule is VALIDATED: unknown `when` types, missing required params (e.g. value) and bad enum values (dir/ref/band) are rejected with the valid options and a closest-match suggestion — nothing lands on disk that can never fire. Re-adding a rule with

• monitor__watch_list

  Return the persisted watchlist (every symbol and its rules).

• monitor__watch_remove

  Remove a symbol from the watchlist, or pass rule_id to remove just one rule. Also clears its edge state and new_filing baselines.

• monitor__rules

  List the supported rule types with params, notes and a copy-pasteable example each — bar rules (RSI/price/%-move/SMA/MACD/Bollinger/rvol) and event rules (earnings_within_days, new_filing, portfolio_weight_above). Call this first to learn what conditions you can set.
