A strategy in LucraX is a single JSON document that specifies:

Which indicators to compute on each bar
When to enter long or short
When to exit (stops, targets, modifiers)
How to size the position
What risk limits to enforce

The engine reads this JSON, computes the indicators on incoming candles, and fires entries / exits based on the rules. Everything is explicit - there is no hidden state or implicit defaults beyond what the Strategy JSON structure spells out.

What a strategy is not

Not a manual trading interface. Strategies execute automatically once enabled.
Not a tracker of arbitrary outside signals. Every input must be computable from the candles the engine ingests.
Not multi-symbol. One strategy trades one symbol on one venue.

Lifecycle in one sentence

A strategy goes draft → backtest → paper / live → stopped, and can be re-run at any stage. See Strategy lifecycle for the full state machine.
