Plan Details

How to choose

Free: single-position money management. Pro: multi-position analysis on the spot. Premium: ongoing management in a Vault and dashboard.

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 for Premium subscribers only.

Customization

Subscribers only · calculator-only scope.

Local-first & Vault

Eliminate risk before the trade. Your data stays with you.

Not an AI feature — pre-trade rule management. Your trade data isn’t handed over; risk is managed inside your encrypted Vault.

Trade data never sent to a server

Your portfolio, rules and journal stay inside the encrypted Vault. They’re never received by SG Group, and never handed to any AI.

Encrypted Vault

Save and reload to resume anytime, and manage multiple portfolios separately. Everything stays in a file on your device, under your control.

Stop risk before you enter

Risk Budget, Rule Compass and the Unusual Activity Signal stop excessive risk before you place the trade.

Who Premium is for

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

Billing & Policy

Payments & refund policy

Payments are processed by Stripe. Choose monthly or yearly (yearly = 2 months off).

Monthly or yearly

Pick monthly or yearly. Yearly equals 10 months of the monthly price (i.e. you save 2 months). Use the switch above to compare anytime.

Changing plans

A change between paid plans is treated as a new subscription to the target plan and triggers a new charge. No prorated refund, offset or credit is applied for the unused period.

Cancellation

Cancelling incurs no additional charge. No prorated refund, offset or credit for the unused period — but you can generally use the plan’s features until the end of the current term.

Stripe Secure payment processing. Checkout runs from the Stripe Buy buttons.

Start free. Step up to Pro or Premium for advanced management.

Single-position money management works out of the box in the Free plan. If you need combined multi-position risk, correlation, margin-level analysis, ongoing management in the Vault or customization, tell us your trading style.
