Volatility % (Standard Deviation of Returns)

This script takes closing prices of candles to measure the Standard Deviation (σ) which is then used to calculate the volatility by taking the stdev of the last 30 candles and multiplying it by the root of the trading days in a year, month and week. It then multiplies that number by 100 to show a percentage.

Default settings are annual volatility (252 candles, red), monthly volatility (30 candles, blue) and weekly volatility (5 candles, green) if you use daily candles. It is open source so you can increase the number of candles with which the stdev is calculated, and change the number of the root that multiplies the stdev.

Updates:
- Changed default levels of the monthly factor from 30 to 21
- Made inputs so it is now possible to change the sample period for the standard deviation and the factor that will multiply the standard deviation. default multipliers are the roots of 5 for weekly, 21 for monthly and 252 for annual volatility.
-Changed default colors and line thickness to make it more bold.
