Taiyoz Gaps

1. Purpose
Tyoz Gaps highlights “gaps” between yesterday’s close and today’s open directly on your chart. A gap occurs when the opening price is significantly above or below the prior bar’s close. By drawing persistent boxes around each gap, you can instantly see where price left a void and monitor when (or if) that void gets completely filled.

2. Gap Detection Logic
Threshold: A gap is only detected if the open-to-previous-close difference exceeds a user-defined “Minimal Deviation” (percentage of the 14-bar average high-low range).

Direction:

Gap Up: today’s open > yesterday’s close

Gap Down: today’s open < yesterday’s close

3. Box Drawing
For each detected gap, the script draws a rectangular box spanning from yesterday’s close level to today’s open level.

Border & Fill Colors are configurable separately for up-gaps and down-gaps.

Boxes extend to the right as new bars form.

4. Display & Filtering Options
Show Gap Up / Show Gap Down toggles let you hide bullish or bearish gaps independently.

Max Number of Gaps: Limits how many boxes remain on-screen; oldest boxes are removed when the limit is exceeded.

Limit Max Gap Trail Length: Optionally force-close any gap box after a given number of bars, even if unfilled.

5. Closing Logic
Full-Fill Only: A gap box stays visible until price fully “fills” it—i.e., for an up-gap, price must exceed the top edge (yesterday’s close); for a down-gap, price must cross below the bottom edge.

Once filled, the box is removed and a “Gap Closed” alert flag is set.

6. Labels & Alerts
Each active gap can optionally show a label at the gap’s lower edge containing:

Absolute size (in price points) and percentage of the gap

Bar count since the gap formed

Label Text Color and Label Text Size are both user-configurable.

Two built-in alertcondition()s fire when a new gap appears or when a gap closes.
