Greater Than¶
Signals · Comparison
True where a > b.
Greater Than is the basic comparison gate: it outputs true on every bar where series A is above series B, and false otherwise. It's how you turn a raw indicator value into a yes/no trading condition — "is RSI above 50?", "is price above the moving average?", "is ADX above 25?" — that you can then combine with other conditions or feed into an entry.
How it works¶
Each bar the block evaluates A > B and outputs the boolean result. Unlike Crosses Above (which fires only on the transition bar), Greater Than is a state: it stays true for the entire stretch that A remains above B. A is the value you're testing; B is the reference — wire a Constant for a fixed threshold, or another series for a relative comparison.
When to use it¶
Use Greater Than as a filter or condition, typically combined with others through an And gate: "ADX > 25 AND price > 200-EMA" builds a regime-and-bias filter. Because it's a continuous state, it's ideal for gating (allowing trades only while a condition holds) rather than triggering (firing an entry). If you want just the bar a condition first becomes true, wrap it in an Edge Trigger.
Example¶
A trend-bias gate: feed ADX / DMI into A and a Constant of 25 into B; the true state means "a real trend exists." Combine it with your entry trigger through an And gate into a Tester so you only trade when ADX confirms strength. Backtest in the Tester.
Tips & gotchas¶
- State, not event. True the whole time A > B — wrap in Edge Trigger for just the first bar.
- Use a Constant for thresholds; both inputs are series.
- Great for gating in an And/Or chain; less ideal as a lone entry (it would fire every bar).
- Mirror is Less Than.

Inputs¶
| Socket | Type | What to wire in |
|---|---|---|
| A | series / bars |
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. BARS uses close. |
| B (optional) | series / bars |
Right-hand series — the REFERENCE being crossed. In an MA crossover this is the SLOW line (e.g. EMA-50). BARS uses close. Leave it unwired to compare against the fixed value below. |
Outputs¶
| Output | Type | Plots as | Description |

Signal arrows | Boolean result of the comparison |
Parameters¶
| Parameter | Type | Default | What it does |
|---|---|---|---|
| B | number · -1000000.0–1000000.0 | 0.0 |
Compared against when the B socket is unwired (e.g. 30 for an RSI trigger). |
