Aroon

What does Aroon measure?

A pair of 0-100 meters for how RECENTLY the market set a new high and a new low. Fresh highs with stale lows is the picture of a healthy uptrend.

How is Aroon calculated?

Look back over the last 14 candles and find how long ago the highest high happened, and how long ago the lowest low happened. A brand-new high scores 100, one that is 14 candles old scores 0. `osc` is simply the up meter minus the down meter.

Written by reading the engine’s real computation, not a textbook — where the two differ, the page describes what actually runs.

How do I use Aroon in a bot?

In the builder, add an indicator of type aroon (parameters: length, default 14). Its output series — up, down, osc — become operands you can compare in any entry or exit rule. The engine grades the whole rule honestly: real fills, no look-ahead, half the history held back.
