Definitions

In plain terms

The transition normally publishes a prior extreme-derived level, reseeds the opposite EP, and resets acceleration.

Technical

The contract freezes penetration field, strictness, publication value, new state, EP seed, AF reset, and same-bar update order.

Scope

A reversal is an algorithm state change, not proof that a market trend will persist.

Examples

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

Common misconceptions

  • A reversal is an algorithm state change, not proof that a market trend will persist.
