This indicator marks swing highs and swing lows on the chart, and it never repaints. A swing is drawn only after the bars that confirm it have closed, so what you see today is exactly what the chart will still show tomorrow.
How it works
Unique stair-step trend trading with the Stairsteps Expert Advisor. Innovative approach for consistent results. Learn more.
A bar is a swing high when its high is above the highs of the N bars on its left and not below the highs of the N bars on its right. Swing lows use the same logic, mirrored. The bar that is still forming is never used, and a swing is drawn only when all N confirming bars on its right have closed.
Nothing is drawn early and nothing is removed later. This makes the swings safe as a building block for BOS / CHoCH logic and for backtests. The cost of this honesty is a lag of N bars: that lag is unavoidable for any swing that cannot repaint.
Inputs

Notes
This is a drawing tool, not a trading signal, and it makes no claim about profitability. It works on any symbol and timeframe.
