This Pine Script indicator, titled "High and Retracement Finder," is designed to identify significant highs and lows on a price chart based on a user-defined starting point and retracement threshold. It begins analysis from a manually set bar index and tracks the highest high until the price retraces by a specified percentage (retracement threshold). Once this retracement occurs, it switches focus to finding the lowest low. If the price surpasses the previous high during this phase, the cycle resets, and the script resumes tracking a new highest high. The script visually marks these significant highs and lows with arrows on the chart, helping traders identify potential turning points or retracements in the market.
