Changed Percentage Labels - Quan Dao

This overlayed utility is used for showing the volatality of the price.

It is useful to see the changed percentage of the price in order to decide what stock/crypto to buy, b/c if the volatility (changed percentage) is high it's likely that you can make bigger profit.

Added option to display changed percentage for:
- Current Close price compared to previous Closed price.
- Close price compared to Open price.
- High price compared to Low price.

As a limit of current pine script, it can only show the last 50 labels for now.
