The Main Purpose of this indicator is to see, if the Trend is accelerating or decelerating.
The first Blue bar will caution when a strong trend is losing strength. I will leave the rest for you to explore.
I picked AAPL again, because it does have both up and down trend, in the recent time.
Mistake in the code
