Definitions

In plain terms

It converts the sign change of oscillator-minus-signal into an event instead of repeatedly flagging every bar above or below.

Technical

Scope

A crossover is a descriptive event and does not guarantee a durable reversal.

Examples

  • A governed lesson calculates or identifies Signal-Line Crossover only after its parameters, state, timing, and edge cases are declared.

Common misconceptions

  • A crossover is a descriptive event and does not guarantee a durable reversal.
