How AI parsing works

When you submit a strategy description, Coinrule runs it through an AI pipeline to produce executable Python.

Stage 1 — Language detection

A lightweight heuristic checks whether the input looks like Pine Script, Python, or natural language. This is a keyword scan in the same request — not a separate network call.

Stage 2 — AI strategy generation

The description is sent to an LLM together with the platform's system context (supported indicators, exchange market config, allowed patterns). The model returns a structured tool call containing:

• name and description
• markets — market config (symbol, venue, interval, asset type)
• position — direction (long / short / both), sizing, and risk parameters (stop loss, take profit, trailing stop)
• settings — order type, max open positions, and other runtime settings
• entry_condition and exit_condition — human-readable summaries
• strategy_py — the full Python source of the strategy

Model used for parsing: claude-sonnet-4-6 (3× credit multiplier). Strategy parsing always uses Sonnet — users cannot manually select a different model for this step.

Stage 3 — Validation

Before the strategy can be launched, the generated Python is validated (security checks, import whitelist, pattern checks). Validation runs server-side and blocks unsafe code.

Stage 4 — Test generation (background)

After you review and launch a strategy, a background task generates a test file using claude-sonnet-4-6 (3× credit multiplier). The test file is required before the engine loads the strategy. This happens automatically; you don't need to do anything.

How are credits charged?

You are charged for the LLM call when the parse succeeds. A failed or rejected parse does not charge credits. The credit cost is shown after parsing completes, before you launch. See Credit drivers and costs.

How do you iterate on a parse?

If the parsed strategy doesn't match your intent, edit your description and re-submit. Each re-parse is an independent LLM call (and a separate credit charge). There is no partial-update / delta-parse feature — each submission generates a fresh strategy.
