Code Review

Use a simple state machine to make EA behavior understandable.

A state machine prevents the EA from mixing setup detection, order execution, position management, and cooldown into one unreadable tick loop.

Define lifecycle states

Keep the states simple and tied to actions the EA can explain.

Waiting

SignalDetected

RiskApproved

OrderSent

PositionOpen

Cooldown

Control transitions

Every transition should have a reason and a log entry. That makes stuck states easy to diagnose.

Signal true

Risk gate passed

Order accepted

Position closed

Avoid hidden side effects

A state function should not secretly bypass risk checks or send orders without updating state.

One execution path

Explicit block paths

Consistent timestamps
