Security & Privacy

Your data never
leaves your machine.

Meridian runs entirely inside NinjaTrader 8 on your Windows PC. There is no cloud backend, no external data collection, and no requirement to share credentials with any party other than your existing broker and NinjaTrader license.

What Meridian stores — and where

Session behavioral data — PSI scores, signal readings, composure grades, trade counts, and timestamps. Stored in a local database on your Windows PC.
Your configuration — Guard rules, session parameters, baseline preferences. Stored locally in NinjaTrader's standard add-on data path.
Up to 5 years of history — all stored on your machine. Uninstalling Meridian removes the software; your local data files remain under your control unless you delete them.

What Meridian does not do

Does not transmit your trade data — fills, P&L, positions, and account details never leave NinjaTrader's local environment through Meridian.
Does not require broker credentials — Meridian reads execution data from NinjaTrader's internal data layer, not directly from your broker's API. No passwords or API keys are ever passed to Meridian.
Does not auto-liquidate positions — Guard can block new order entry and, at the highest enforcement level, disconnect the broker connection (which prevents new orders but does not force-close open trades). Closing existing positions always remains in your hands.
Does not provide trading signals — PSI is a behavioral stability score, not a directional indicator. Meridian generates no buy or sell signals and offers no investment advice.
Does not use third-party analytics or telemetry — no usage events, crash reports, or behavioral analytics are sent to external services. The software has no built-in tracking.

The only external connection

Meridian makes one type of external network request: license validation via Whop. When Meridian starts, it checks that your subscription is active. This request contains only a license identifier — no trade data, no account information, and no personally identifiable information beyond what Whop holds as your subscription provider.

If you have questions about how Whop handles subscription data, their privacy policy is available at whop.com/privacy.

What Guard enforces — and what it cannot touch

Guard blocks new order entry at the NinjaTrader platform level when a configured threshold is crossed. It intercepts the order before it is submitted — it does not interfere with orders already in the market.

Guard does not force-close open positions. If Guard locks new entries while you have a live trade, you can still exit that trade normally through NinjaTrader. The lockout applies to new entries only.

Broker disconnect mode (the highest enforcement level) terminates NinjaTrader's broker connection. This prevents all new order activity — including exits — until you reconnect. This mode is an advanced option intended for situations where full disengagement from the market is desired. It should be understood and tested in simulation before being used live.
