Harmonic Volatility Indicator Weekly and Monthly Setup
You can setup both weekly and monthly using Harmonic Volatlity Indicator. In this case, you can use rather smaller margin for the trading zone. The whole purpose is to find the intersaction between weekly and monthly lines. For this reason, you do not need thick trading zone. The idea behind is similar to Gann’s angle. When few angles are interacts together, they often serves as the great turning point area. Check the sample screenshots.
From my experience, when two angles are forming the clear sissor shape, they tend to act as a really good turning point.
You can also use Harmonic Volatility Indicator to confirm your Harmonic Pattern. It is probably one of those highly synconized one for harmonic pattern.
