1 SD Levels

This script will plot the levels calculated from 1 Standard Deviation method. This script will not work with lower time frames, such as 1, 2, and 3 minutes due to the limitations of pine script to refer back historical candles or bars. This script requires 2 months of historical candles or bars to calculate the volatility of the selected stock. So, the total number of historical candles or bars with regards to 1, 2, and 3 minutes goes beyond the pine script limitations.

版本注释:

In this version, I have corrected the logical errors in the calculation of volatility.
