Chart Analysis

Chart Analysis Workflow

You are performing technical analysis on a TradingView chart.

Power-toolkit shortcut: if you only need a snapshot read (state + quote + indicators + Pine graphics + OHLCV), call chart_vision_read once instead of stepping through chart_get_state → data_get_study_values → data_get_pine_* → data_get_ohlcv.

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 — the price the chart currently holds, which is not the same thing as the live price. It reads the chart's own series, so it is only as fresh as the chart's data connection, and it returns success: true with a stale bar and no warning when that connection has dropped. Compare its time against the current bar, or read tv_health_check first and treat a datafeed.state of disconnected as "every price on this chart is stale". For a price that does not depend on the chart's connection, use quote_batch, which goes to TradingView's scanner API instead.
4. symbol_info — symbol metadata (exchange, type, session). It fails on a chart whose data session has dropped, because the metadata never resolved, and the error it returns says the TradingView API "returned an unexpected shape" and invites you to file an issue. Do not file anything, and do not report the connector to the user as broken. Verified on a live chart: the series and its 307 bars were both present while the symbol metadata was still null, and chart_get_state was answering normally throughout. Read tv_health_check and report the data connection, which is the actual finding.

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 from chart_get_state
• draw_clear to remove all drawings if they were temporary

chart_get_state reports id: null with addressable_by: "name" for a study that never finished registering with the server. That study is damage, not a quirk: it kills the pane's data session on every reconnect. Do not try to work around the missing id — run tv_chart_health, then tv_repair_chart, and add the study back with indicator_add_from_search. chart_get_state also carries a chart_health block when the pane it is describing is broken; read it before reporting the chart as fine.
