In version 6.3, we have made some minor improvement on Harmonic Volatility Indicator.

Harmonic Volatility Indicator is the first technical analysis applying the Fibonacci analysis to the financial volatility. Harmonic volatility indicator is another level of price action trading tool, which combines robust Fibonacci ratios (0.618, 0.382, etc.) with volatility. Originally, Harmonic Volatility Indicator was developed to overcome the limitation and the weakness of Gann’s Angle, also known as Gann’s Fan. We have demonstrated that Harmonic Volatility Indicator can be applied in a similar manner to Gann’s Angles (or Gann’s Fans) to your chart. At the same time, since the volatility is important information for traders, Harmonic Volatility Indicator can bring many other benefits for your trading. Harmonic Volatility Indicator can be incorporated to your existing technical analysis. It is also very effective in spotting mature trend or breakout phase. You can use this tool to identify the significant support resistance levels, trend reversal point and breakout trading.
