NXOGX By AYRUS

It plots gap zones on the chart — for example, NDOG (New Daily Open Gap) or NWOG (New Weekly Open Gap) — using only border lines (no filled boxes).
Each gap zone shows:

A top line and bottom line (solid and thick),

A middle dotted line (center of the gap),

A label (e.g. “NDOG”) placed slightly beyond the right edge of the zone,

The lines extend 5 bars beyond the most recent candle.
