Hold

Signals · Utility

Latch the signal true for N bars after each rising edge.

Hold latches a signal true for a set number of bars after it fires. A one-bar pulse goes in; a steady true lasting N bars comes out. It's how you give a brief event a window — "this trigger stays valid for the next 3 bars" — so other conditions have a chance to line up with it instead of needing to coincide on the exact same bar.

How it works

The block watches the input for a rising edge (a false→true transition) and, on each one, holds its output true for Hold bars (default 3) bars before releasing. If the input fires again during a hold, the window extends from the new edge. The effect is a debounce-and-stretch: momentary signals become short sustained windows.

When to use it

Use Hold to widen a trigger's window so it can combine with other conditions that won't always agree on the very same bar. The classic case: a Liquidity Sweep or Crosses Above happens on one bar, but your confirming condition (a structure shift, a zone touch) lands a bar or two later — wrap the trigger in Hold so it's still "active" when the confirmation arrives, then And them. It's also a simple way to keep a signal alive long enough for an entry to process.

Example

Combine signals that fire a bar apart: take a Liquidity Sweep event, pass it through Hold with 3 bars so it stays active, then And it with a bullish Market Structure confirmation that may print a bar or two later — into a Buy Signal. Backtest in the Tester.

Tips & gotchas

• Stretches a pulse into a window — the fix for "two signals that rarely fire on the exact same bar."
• Re-firing extends the window from the new edge.
• Mind double entries — a held signal stays true for N bars; pair with an Edge Trigger downstream if you need a single entry from the combined logic.
• Opposite intent to Delay — Hold keeps a signal alive now; Delay moves it later.
