Fibonacci Bollinger Bands
These Bollinger bands feature Fibonacci retracements to very clearly show areas of support and resistance . The basis is calculate off of the Volume Weighted Moving Average . The Bands are 3 standard deviations away from the mean. 99.73% of observations should be in this range.
