Previous and Penultimate Swings (Single Timeframe • 4 lines)

121
Using chat GPT I've created a swing high and swing low horizontal indicator that helps me personally visualize significant levels.
In particular penultimate swing highs and penultimate swing lows. Hopefully this can help another trader or many! You can add or remove any of the 4 levels. Adjust the lookback period. And extend each line individually to the right of price action.
