03 — About the plans

Plan details & how to choose

The decisive difference between Pro and Premium: Pro focuses on analysis of multiple positions. Premium adds ongoing management in an encrypted Vault and a dedicated dashboard, behavioral-risk tools (Risk Budget / Rule Compass / Unusual Activity Signal / Trade Journal), stress testing, integrations, and optional customization (subscribers only). If you run this as an ongoing process rather than a one-off calculation, Premium is the better fit.

Free

Single-position money management

Before entering, check the right lot, required margin, loss at the stop and effective leverage. Unlike a typical lot calculator, it shows which constraint binds — risk or margin.

Pro

Multi-position risk analysis

Analyze combined risk across concurrent positions, currency/index concentration, correlation, and average price & total risk when averaging down or pyramiding. Manage per-symbol and per-broker contract specs in one place.

Premium

Vault, dashboard + customization

Save portfolios in an encrypted Vault and a dedicated dashboard, and manage them over time. Behavioral-risk tools (Risk Budget, Rule Compass, Unusual Activity Signal, Trade Journal), margin-level scenario analysis, stress testing, and CSV / trade-history integration. Customization is available to Premium subscribers only.

Not an AI feature. No trade-data upload. Your risk rules, portfolio and journal stay inside your encrypted Vault.

Risk Budget, Rule Compass and the Unusual Activity Signal stop excessive risk before you enter, while your portfolio, rules and journal are managed entirely inside an encrypted Vault file. Save and reload to resume anytime, and manage multiple portfolios separately. Your trading data is never sent to a server, never received by SG Group, and never handed to any AI. Everything stays in a file on your device, under your control.

Who Premium is for

Businesses, small teams & pro traders

Best for ongoing operation across multiple accounts or a team, for professional traders running a disciplined process, and for management spanning several currencies, indices and commodities. Individuals are welcome too.
