About

SCT Suite

Features
Read full description

SCT Suite is the official companion app for active members of Strategic Capital Technologies — including SCT Unlimited licensees, SCT Flex subscribers, and SCT Inner Circle members. WHAT THE APP DOES • TRADE JOURNAL Log every fill from your broker account. Connect a supported broker for automatic sync, or enter trades manually. The journal organises every position by instrument, session, and date — with notes, screenshots, and tags. Live and demo accounts are tracked separately, so paper-trading performance never gets mixed with real money. • PERFORMANCE BREAKDOWN Review your account performance over any time window. The app surfaces standard journal statistics — win rate, average R:R, profit factor, drawdown, equity curve, and P&L over any time window — calculated entirely from your own logged data. No predictions, no projections — just a clear view of what you have already done. • ALGORITHM REVIEW (Unlimited & Flex members) For members running SCT algorithms, the app provides a separate view that breaks down algorithm-attributable activity in your account. Filter by algorithm, by session, by configuration. Compare across time periods. • DIRECT SUPPORT 1-on-1 messaging with the SCT support team — built into the app. Ask questions about your membership, methodology, or onboarding. No tickets, no email chains. Conversations stay accessible across sessions. • NOTIFICATIONS Opt in to push notifications for closed trades, daily performance summaries, and tier-specific alerts. Notifications are delivered instantly and can be disabled at any time from Settings. • SIGN-IN & SECURITY Sign in with Face ID, Touch ID, or your member password. Credentials are stored in the device's secure enclave and never leave the phone. All connections are HTTPS-only. • MULTI-DEVICE ACCESS Your journal, performance data, and chat history sync across iOS, and the SCT Suite web dashboard at app.sctsuite.com. WHO THE APP IS FOR The app is for existing SCT members across all three product tiers: • SCT Unlimited — algorithmic trading software licensees • SCT Flex — subscribe to SCT's algorithmic trades, on personal capital, at your discretion • SCT Inner Circle — community membership Anyone without an active SCT membership will not be able to sign in. BROKER INTEGRATION Broker integration is optional. Members who connect a supported broker get automatic trade logging. Members who prefer not to connect can enter trades manually — every journal feature works with manually-entered data. When a broker is connected, the app reads trade history only. The app cannot place orders, modify positions, or move funds. SCT does not access client capital under any circumstance. Broker authentication uses OAuth — your broker password is never seen or stored by SCT, only short-lived access tokens. DISCLOSURES Strategic Capital Technologies LLC is a software and education provider, not a registered investment adviser, broker-dealer, commodity trading advisor, or fund manager. The app does not execute trades, hold funds, or manage capital. All content is for general educational purposes. Trading and investing involve substantial risk, including total loss of capital. Past performance does not guarantee future results. Not available in all jurisdictions. Users are responsible for compliance with applicable local law.
