Compiler Fixes

Use a complete OnInit and OnTick skeleton before adding strategy logic.

A useful EA skeleton does more than compile. It separates initialization, market reading, risk gates, signal logic, execution, and logging so future debugging stays controlled.

Search intent

The developer needs a clean Expert Advisor scaffold instead of a partial snippet.

Paste compiler errors / Generate EA draft / Get risk check

Short opt-in only. We store one source, one intent, and one new lead status. No scraped lists, no purchased contacts, no trading promises.

Choose the workflow you want, then opt in so the CRM source is measurable.

Initialize inputs and handles

OnInit should validate inputs and create indicator handles when the EA uses indicators. It should fail fast if critical inputs are invalid.

Validate risk percent

Validate spread and session settings

Create and check indicator handles

Keep OnTick readable

OnTick should read market state, run gates, evaluate signals, then execute. It should not become one giant block.

Read bid, ask, spread, and time

Run risk and exposure guards

Call entry logic only after filters pass

Log decisions, not noise

Logs should explain why a trade was allowed or blocked. Excessive tick logs make real issues harder to find.

Log block reasons

Log order request details

Log state changes only when they matter
