Deregister an indicator from the session registry — ledgr_deregister

Removes an indicator registration from the current R session. This only affects the in-memory registry used for interactive lookup and tests; it does not alter any persisted snapshots, runs, features, or ledger artifacts.

Usage

ledgr_deregister_indicator(name, missing_ok = TRUE)

Arguments

name: Indicator registry name.
missing_ok: If TRUE, missing names are ignored. If FALSE, missing names are an error.

Value

Invisibly returns TRUE when an indicator was removed and FALSE when the indicator was already absent and missing_ok = TRUE.

Examples

local({
  ind <- ledgr_indicator(
    id = "example_deregister",
    fn = function(window) tail(window$close, 1),
    requires_bars = 1
  )
  ledgr_register_indicator(ind)
  ledgr_deregister_indicator("example_deregister")
})
