What a follower does when the leader's instant falls between its bars.
nearest (default): show the crosshair on the last bar that had OPENED by
the leader's instant. A hole inside the follower's history is a missing bar,
not a missing instant, and snapping to a real bar reads as "this one lines
up" where a line floating between two candles belongs to neither.
Deliberately not the closest bar by timestamp. A bar is stamped at its open
and lasts until the next one opens, so past the halfway point of a daily bar
the arithmetically nearest stamp is tomorrow's, and the follower would
highlight a candle that did not exist yet at the leader's instant.
hide: draw nothing unless the follower has a bar at exactly that time.
For a workspace where a linked crosshair is a data claim.
Both policies refuse to answer outside the follower's coverage: an
instant before its first bar or after its last one is not a gap in its data,
it is a period the chart does not cover at all, and pinning the crosshair to
the first or last bar there would assert an alignment that does not exist.
