VQZL Z-Score

Volatility Qaulity Zero Line attempts to keep a trader out of ranging markets, but the original calculation on TradingView had to be adjusted for each instrument. To avoid this issue, I have applied a z-score calculation to the VQZL so the result is standardized for all instruments. A Z-Score is simply a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean.

This calculation allows us to compare current volatility to the mean (moving average) of the population (Z-Length). The closer the VQZL Z-Score is to the mean, the closer it will be to the Zero Line and therefore price is likely consolidating and choppy. The farther VQZL Z-Score is from the mean, the more likely price is trending.

The MA Mode determines the Moving Average used to calculate VQZL itself. The Z-Score is ALWAYS calculated with a simple moving average (as that is the standard calculation for Z-Score).

The Threshold Levels are the levels at which VQZL Z-Score will change from gray to yellow, orange, green ( bullish ), or red ( bearish ). These levels can be adjusted but you should adjust the Threshold Lines as well (in the style section), so they line up with your adjusted values.

Statistically speaking, confidence levels in relation to Z-Score are noted below. The built in Threshold Levels are the positive and negative values for 90%, 95%, and 99%. This would indicate when volatility is greater than these values they are out of the ordinary from the standard range. You may wish to adjust these levels for VQZL Z-Score to be more responsive to your trading need
80% :: 1.28
85% :: 1.44
90% :: 1.64
95% :: 1.96
99% :: 2.58

As always, trade at your own risk.

Very nice work. Regarding your line comment "// Natural logarithm (ln(2/(SC+1))) workaround"... Pine's log function is actually natural log.

@allanster, good to know! I actually didn't code that part, it's a block of code used from a multi-MA code somewhere that's been handed down the generations haha

@allanster, perhaps at one point (in another version) it was different? i genuinely am not sure

@eylwithsteph, I think it has always been natural log, but it is not well known.
