How signal behaviour is classified

Research question

Given a visual trading template’s source, which of five behaviour classes truthfully describes what a trader would have seen live?

Method

1. Static analysis of the generated Pine/MQL looks for reads of bars that close after the signal bar, including look-ahead patterns the factory already refuses at validation time.
2. Confirmation-based tools — those that can print on the live bar and withdraw before the close — are labelled separately from historical repainting.
3. Adaptive structure tools (swings, ZigZag-like drawings, channels that move) are labelled as adapting to new bars rather than as non-repainting.
4. Forward paths are labelled as projection: scenarios from current structure, redrawn as the market moves, not predictions.

The five classes

Non-repainting

Once a signal is printed on a closed bar it never moves or disappears. What you see in history is what you would have seen live.

Confirmation required

Signals are evaluated on the live bar and only become final when that bar closes. A signal can appear and then withdraw before the close.

Adapts to new bars

Levels and structure are recalculated as new bars arrive, so drawings on the chart shift over time. This is how the tool is designed to work — it tracks the market as it evolves.

Repaints

Historical markers are placed using bars that came after them, so the chart history looks cleaner than what you would have seen live. Use this tool for context, not as a record of past calls.

Forward projection

Draws possible future paths. These are scenarios derived from current structure, not predictions, and they are redrawn as the market moves.

Limitations

• The label describes drawing behaviour. It is not a quality score and it is not a performance claim.
• A non-repainting marker can still be a poor trading idea. Behaviour class and usefulness are different questions.
• Reviews and star ratings are emitted only when a verified purchase exists. They are not part of this classification.
