VDVA - Volume Delta Volatility Amplifier

This script defines an indicator named VDVA (Volume Delta Volatility Amplifier), which combines volume delta (the difference between volume up and volume down) and volatility (ATR) into one line. This line is then smoothed using a moving average and compared with the zero level and a shorter-period moving average. The script also plots shapes when the rate of change of the line exceeds the first standard deviation. Moreover, the script uses Bollinger Bands and Keltner Channels to determine the squeeze condition, which is a signal of a potential breakout. Finally, the script plots two bar charts that show the volume up and volume down multiplied by ATR.
