OPEN-SOURCE SCRIPT

Extension %

Updated
This is a tracking tool to measure two different kinds of distances:
- Gaps, from the open/close or the high/low value to the nearest open/close or high/low value.
- Price extensions of one or two candles from a preferred starting point (open, high, low or close) to a final point (open, high, low or close). The two-candles mode includes an optional rectangle to help you visualize the first and the last point of the measurement.

The script will plot a label with a percentage when the extension reaches the value you set. Unless you choose to track the one-candle price extension, the label will always be displayed on the high/low value of the second candle.

Release Notes
Update:

UPDATE:

Now you can choose to measure the extension in percentage, price, or ticks. On any financial instrument, the script will reproduce the same value as the one calculated by TradingView's Price Range.
Release Notes
UPDATE:

1) You now have the flexibility to display extensions in a single direction of your choice.

2) To visually represent the direction of the extension, two distinct colors are at your disposal.
Release Notes
UPDATE

Added the option to view the extension on daily charts on earnings days only, in order to study the historical performance of stock titles.
