Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

chart-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Chart Analysis Workflow

You are performing technical analysis on a TradingView chart.

Step 1: Set Up the Chart

  1. chart_set_symbol — switch to the requested symbol
  2. chart_set_timeframe — set the appropriate timeframe
  3. Wait for the chart to load (the tool handles this)

Step 2: Add Indicators

Use chart_manage_indicator to add studies. Common names (must use FULL names):

  • "Relative Strength Index" (not RSI)
  • "Moving Average Exponential" (not EMA)
  • "Moving Average" (for SMA)
  • "MACD"
  • "Bollinger Bands"
  • "Volume"
  • "VWAP"
  • "Average True Range"

After adding, use indicator_set_inputs to customize settings (e.g., change EMA length to 200).

Step 3: Navigate to Key Areas

  • chart_scroll_to_date — jump to a specific date of interest
  • chart_set_visible_range — zoom to a specific date window
  • chart_get_visible_range — check what's currently visible

Step 4: Annotate

Use drawing tools to mark up the chart:

  • draw_shape with horizontal_line for support/resistance
  • draw_shape with trend_line for trend channels (needs two points)
  • draw_shape with text for annotations

Step 5: Capture and Analyze

  1. capture_screenshot — screenshot the annotated chart
  2. data_get_ohlcv — pull recent price data for quantitative analysis
  3. quote_get — get the current real-time price
  4. symbol_info — get symbol metadata (exchange, type, session)

Step 6: Report

Provide the analysis:

  • Current price and recent range
  • Key support/resistance levels identified
  • Indicator readings (RSI overbought/oversold, MACD crossover, etc.)
  • Overall bias (bullish/bearish/neutral) with reasoning

Cleanup

If you added indicators the user didn't ask for, remove them:

  • chart_manage_indicator with action "remove" and the entity_id
  • draw_clear to remove all drawings if they were temporary

Context Management

  • Use summary: true on data_get_ohlcv
  • Call chart_get_state once at start to get indicator entity IDs
  • Screenshot is preferred over large data dumps for visual context
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
