Auto Pattern Recognition and reversal candidates with Pattern Radar
Use Founder Pattern Radar to inspect chart structures, reversal candidates, confirmation boundaries and drawing-based alerts in Basis.
From pattern to an actionable review
- 01
Open Pattern Radar
Choose Pattern Radar in the terminal panel menu or command palette. All matching setups appear automatically on the chart, including resolved history. It scans completed raw OHLCV candles loaded for the current venue, symbol and timeframe, up to the terminal’s 50,000-bar history limit. Choose a time-based chart from 1m through 1M; range bars and 1-second data are not substituted with another interval.
- 02
Choose the swing scale
Fast, Balanced and Major require 3, 5 or 8 completed candles on each side of a swing. Larger scales reveal broader structures later. Set one or two consecutive completed closes for breakout confirmation and adjust the minimum rule-confluence score.
- 03
Inspect a candidate
Filter chart patterns or reversal points, direction and lifecycle. Each card plots actual chart data and explains its geometry and supporting evidence. Highlight levels emphasizes one setup and its confirmation, invalidation and measured reference without hiding the others. The overlays are temporary and read-only; they do not alter saved drawings. Use a linear price scale and a regular time axis.
- 04
Explore older patterns
Pan left to load earlier candles. The scan queue prioritizes visible history and reports its completed-candle coverage. Overlapping scan windows preserve context across page boundaries. Sidebar cards load in batches, but this never limits the number of matching chart overlays. Zoom in when labels are crowded: outlines and reversal markers remain visible even when every label cannot fit. Turn off Automatic chart overlays or close the panel to clear the pattern layer.
- 05
Review an alert draft
Alert at boundary opens the existing alert builder with pinned anchors and the original ATR margin. Review, choose delivery and save to arm it. This alert watches the saved line, not the complete pattern: it does not automatically expire or re-detect a changed formation. Live alert creation is disabled during replay.
What the scanner looks for
- Ten geometric structures: double top and bottom, head-and-shoulders and its inverse, ascending/descending/symmetrical triangles, rising/falling wedges, and rectangles.
- Reversal candidates combine a known swing level or prior 20-bar sweep with price response. Wick rejection, body engulfing, RSI(14) divergence/context and relative volume can add evidence. RSI alone is not a reversal detector.
- Triangles and wedges require three confirmed tests per boundary, containment and acceptable line fit. Double formations and shoulders require separated, proportionate swings; a neckline break is distinct from a candidate.
Watching is not confirmed
| State | Meaning |
|---|---|
| Watching | The geometry meets the rules. Price has not completed the required breakout closes beyond the boundary plus its 0.1 ATR margin. |
| Confirmed | One or two required consecutive closes have passed the boundary. This is not a guarantee of continuation. |
| Invalidated | Price breached the opposing boundary before confirmation, or touched the recorded invalidation after confirmation. |
| Reference reached | A subsequent bar reached the geometric measured-move reference. This is not a simulated trade or a realized return. |
| Expired | The structure aged beyond its observation window or its converging boundaries met. |
Important
The confirming candle’s earlier wick cannot count as post-confirmation success. If a later candle touches both reference and invalidation, invalidation wins because OHLC data cannot tell which happened first.
Evidence, not a win-rate promise
The 0–100 score adds the displayed rule-confluence weights and caps them at 100. It is not calibrated probability, a backtest win rate or a recommendation to buy or sell.
A pivot only becomes usable after its right-hand candles close. The blue knowable marker refers to the opening timestamp of the candle whose close made it usable, not the original swing. Historical candidates retain that detection time. Status can change as new candles arrive.
Only loaded history is scanned, subject to exchange availability and the terminal’s 50,000-bar limit. There is no last-800-bar or last-160-bar reversal cutoff. A structure may span at most 400 candles; the initial edge of available history has less warm-up context. Gaps and missing volume are flagged. Exchange corrections or changes to loaded history can change a result. All patterns means all candidates meeting the selected detection rules and filters, not every possible interpretation of a chart.
Patterns use raw OHLCV even on Heikin Ashi and other transformed displays. Inspect the regular candlestick chart when comparing boundaries. Turning points are candidates, not future prices known in advance.
