Definitions

In plain terms

Neither upward nor downward range expansion strictly wins, so Wilder directional movement is normally zero on both sides.

Technical

Detection freezes strict or inclusive containment, bar finality, consecutive ordering, and adjustment basis.

Scope

Inside-bar geometry does not mean the candle body or close is unchanged.

Examples

  • A governed lesson calculates or identifies Inside Bar only after its parameters, state, timing, and edge cases are declared.

Common misconceptions

  • Inside-bar geometry does not mean the candle body or close is unchanged.
