What is ta.iii in Pine Script?

ta.iii is the Intraday Intensity Index series, relating where the close falls within the bar to volume, highlighting pressure on up-close vs down-close bars.

How is the Intraday Intensity Index calculated?

A common formulation weights the close position in the range: (2×close − high − low) divided by range and volume terms; Pine implements the official variant as ta.iii.

How do I use III for trading?

Use III with price action: sustained positive values on rallies or negative on declines can confirm direction; divergences vs price may warn of fading pressure.
