This Pine Script calculates the average volatility over the past 20 bars by taking the difference between the high and low prices. It then adjusts this volatility based on the previous closing price: if the price is below $20, the volatility is multiplied by 2, and if it’s above $20, the volatility is multiplied by 1.5. The adjusted volatility is then plotted on the chart, helping traders visualize how volatility changes relative to the asset's price level.
