Do The Signals Repaint?

Patterns are evaluated on bar close and do not repaint intrabar. Once a candle has closed with a pattern color and label, that label stays exactly where it printed. While the current bar is still forming, its color can update tick by tick — that is the live bar developing, not a repaint of history.

Two related behaviors are worth knowing so nothing surprises you:

• Swing lines confirm late by design. A liquidity line appears 3 bars after the actual pivot, because the pivot needs 3 confirming bars to the right before it exists. The line is drawn back to the true swing point, but you will never see it on the bar where the swing happened.
• Developing extremes update live. Current Week High and Current Week Low (CWH/CWL) track the developing extremes of the week, so they move whenever price sets a new one. Treat them as live context, not as fixed backtestable levels. Previous Week High and Previous Week Low come from the closed week, while Current Day Open is fixed when the day begins; none of those three levels moves intraday.

Why Did A Candle Change Color?

Candle color comes from two layers. The base layer is the trend engine: neon green in an uptrend, neon red in a downtrend. On top of that, a confirmed pattern overrides the trend color with its own signature color for that one candle.

So a color change is one of two things:

• A trend flip. The trend engine switched direction — either the SSL channel crossed, or a reversal pattern or a decisive momentum candle through the prior extreme forced the flip immediately. All candles from that point on take the new trend color.
• A pattern override. A single candle wears a pattern color (with its label) while the candles around it keep the trend color.

Indecisive candles (small body) are a third look, not a signal: they keep the trend color on wicks and borders but get a contrasting body fill so chop stands out. The full priority chain is explained in Trend Engine.

The Chart Has Too Many Drawings, Or Old Lines Are Disappearing

Artemis Pro keeps its swing lines in a rolling set of at most 100 active lines and drops the oldest first when the set fills up, all within TradingView's overall drawing budget of 500 lines and 500 boxes for the script. On very dense charts (fast timeframes, long sessions) that rolling set cycles, which is why very old swing lines eventually vanish.

If the chart feels crowded, or you want the budget spent on recent structure:

• Lower Max Age (Bars) in the Swing Lines group (default 100) so unfilled lines expire sooner.
• Enable Hide Filled so mitigated lines are removed entirely instead of remaining as frozen historical marks.
