Strategy overview
Breakout/momentum strategy on M30/H1 majors with ATR-based stops and take-profit targets. A maximum-exposure governor caps total open lot size regardless of signal count. Equity floor stop is non-negotiable — if equity hits the floor, all positions close.
Capital Builder EA is purpose-built for traders running smaller accounts who want automation without the hidden recovery / martingale logic that plagues most "small account" robots. Micro-lot sizing, capped concurrent exposure, and an equity-floor stop close all positions if the account drops below a configured threshold.
Who it is for
- Traders with $500–$5,000 capital who want disciplined automation.
- Users explicitly opting in to the higher drawdown sensitivity of small accounts.
Who it is not for
- Traders with capital above $5,000 — choose Growth EA or Portfolio AI instead.
- Beginners with no prior live trading experience.
- Anyone uncomfortable with R4 (Growth) drawdown profiles.

FAQ
AlphaLab-AI makes no return promises. Smaller accounts carry higher drawdown sensitivity. The product is designed to give a small account disciplined automation, not to manufacture growth.
