AI Block: Forecast Direction — what it is and how to use it in trading
Definition
Forecast Direction (forecast.direction) is a strategy builder AI block that returns the forecast model's direction for the upcoming bars as one of three values: Long (up), Short (down), or None (no clear signal).
How it works in the builder
An enum operand encoded Short=-1, None=0, Long=1 — compared to a constant with a normal operator in a condition (e.g. forecast.direction == 1). The value is computed ahead of time and read from a cache at signal time; in backtest AI blocks always evaluate to false, and the backend lists them in disabled_blocks.
What it looks like on the chart
Drawn in the builder card as three small directional glyphs (down/flat/up), with only the active one highlighted and labelled.
Typical use
Typical condition: forecast.direction == 1 as an AI long-entry filter, usually paired with forecast.probability > 70 to filter out low-confidence forecasts. Available only in LIVE strategies and only on the Pro plan.
Common pitfalls
Like the rest of the builder, this is an informational and analytical tool, not individual investment advice — the value is probabilistic and doesn't guarantee an outcome. In backtest a condition using this operand is always false — a strategy that depends only on AI blocks can't be tested on history, only run live.
