What it does
Combines wired inputs — indicators, prices, constants — into a custom value via an expression.
What happens
The expression is parsed once when the strategy loads, then evaluated each candle over the resolved inputs.
When to use
Custom indicators, ratios, spreads, or normalized values the built-ins don't provide.
Gotchas
- Reference inputs by the names you declare, not raw node ids.
- Divide-by-zero or a malformed formula errors rather than silently passing a bad value.
