Equal

Signals · Comparison

True where |a - b| is within tolerance.

Equal tests whether two series are the same — within a tolerance you set. Because trading values are floating-point (and rarely exactly equal), the tolerance is what makes this block actually usable: it asks "is A within this much of B?" rather than demanding a perfect match that would almost never happen.

How it works

Each bar the block outputs true where |A − B| ≤ Tolerance. With the default Tolerance of 0.0 it requires exact equality — which is appropriate only for integer-like or discrete series (e.g. a regime code). For any real price or indicator comparison, set a tolerance that reflects how close is "close enough" in that series' units. A and B are both series; use a Constant to compare a series against a fixed value.

When to use it

Equal is most useful for discrete or state-coded series — checking whether a Volatility Regime output equals a specific regime code, or whether two indicators have momentarily converged. For continuous prices, "equal within tolerance" can flag touches of a level, but a Between range test or a crossover is usually the better tool. Reach for Equal when you genuinely need a match, not a direction.

Example

Filter to a specific regime: feed a Volatility Regime Regime output into A and a Constant of 3 (expanding) into B with tolerance 0; the true state means "we're in the expanding regime." Combine with a breakout trigger through an And gate into a Buy Signal. Backtest in the Tester.

Tips & gotchas

• Set a tolerance for real numbers. Exact 0.0 equality almost never fires on prices — it's for discrete codes.
• Tolerance is in the series' own units — match it to the scale you're comparing.
• For levels, prefer Between or a crossover; Equal shines on state codes.
• Both inputs are series — use a Constant for a fixed target.

Inputs

Socket	Type	What to wire in
A	series	Left-hand series — the one DOING the crossing. In an MA crossover this is the FAST line (e.g. EMA-20). In an RSI trigger this is the RSI line itself.
B	series	Right-hand series — the REFERENCE being crossed. In an MA crossover this is the SLOW line (e.g. EMA-50). In an RSI trigger this is the threshold (e.g. constant 30).
