Meridian Guard Review 2026: Is It Worth It for Prop Traders?
Meridian is Windows risk-management software for futures traders that scores trading behavior in real time. Meridian Core is free; Meridian Guard, the paid layer that pauses, blocks or disconnects you when your own rules fire, costs $29.99 a month. It runs inside NinjaTrader 8, with Tradovate and Ironbeam apps in early access, and most of its lockouts only govern the PC it runs on.
Start with free Core: it shows whether you have a tilt problem worth paying to enforce against. Guard makes sense for NinjaTrader 8 or Tradovate futures traders who keep breaking their own daily rules and want hard friction set in advance. It is not device-proof outside Tradovate demo and evaluation accounts, it is Windows-only, and nothing about it guarantees an evaluation pass. This is a research-based review, not a hands-on test.
Key takeaways
- Price: Core free with no card; Guard $29.99 a month, billed monthly through Whop. Code FUNDINGCODES showed $26.99 in our November 5, 2026 unpaid checkout.
- Free Guard access: Meridian says a new free NinjaTrader 8 license includes Guard for its first 7 days, no card.
- Platforms: NinjaTrader 8 add-on available now; standalone Tradovate and Ironbeam apps in early access on the same license; no TopstepX, Mac or mobile app.
- What Guard does: 6 triggers and up to 5 response levels on NinjaTrader 8, up to a broker disconnect; the standalone apps add a 6-tier ladder with a full-screen cool-down wall and a Windows firewall cut.
- Main limit: the only device-proof lock is on Tradovate demo and evaluation accounts; elsewhere a phone or second device is outside Guard.
- Refunds: 14-day money-back guarantee on the first Guard charge, plus a full refund if it will not run on a supported setup and support cannot fix it.
- Evidence limit: we did not install, trade with or trigger Meridian; we checked its public pages and one unpaid checkout.
What is Meridian?
Meridian, at meridianpsi.com, is risk-management software for discretionary futures traders. It is not a prop firm, broker or signals service. Its core idea is the Psychological Stability Index (PSI): a 0–100 score that Meridian says updates after every fill and combines seven behavioral signals, such as revenge entries, oversizing, stop widening and overtrading pace, measured against a baseline built from your own session history.
Meridian says it also enforces the limits a conventional risk tool covers: daily loss, single-trade loss, P&L and drawdown caps, and loss-streak cutoffs. Core adds a session journal, an Intel analytics workspace and 5 years of local session history. Meridian describes itself as an Official NinjaTrader Ecosystem Vendor; its Terms describe the operator only as an independent company and set California law.

How much does Meridian cost in November 2026?
Meridian's pricing page, checked November 6, 2026, lists two tiers in US dollars:
| Tier | Price | What it adds |
|---|---|---|
| Meridian Core | Free, no card | Live PSI score, seven behavioral signals, personal baseline, floating HUD and dashboard, session journal, Intel analytics, 5-year session history |
| Meridian Guard | $29.99 a month | Everything in Core plus self-enforcing rules (6 triggers), Strict Lock, hard limits on contract size and entry order types, pauses and disconnects that survive a restart, priority support |
With FUNDINGCODES, our November 5, 2026 unpaid Whop checkout showed Guard at $26.99 a month, labelled "10% off · All payments." Meridian's partner page says the partner discount applies to every Guard renewal; we have not observed a renewal charge. Some third-party pages we checked on November 5, 2026 still showed older $49.99 and $69.99 prices; Meridian's current pricing page and the checkout both showed $29.99. Full test details are on our Meridian Guard coupon code page.
What can Meridian Guard actually stop?
You choose Guard's rules in advance from six triggers, according to Meridian's Guard page: PSI below a threshold, consecutive losses, session P&L below a limit, unrealized P&L below a limit, a single-trade loss and session time over. Each trigger maps to a response you pick, from a notification or a typed acknowledgement to a trading pause, an entry block or a broker disconnect.
How hard that response bites depends on where it is enforced. Meridian's FAQ is unusually direct about this:
- In the app: alerts, acknowledgements, pauses, Strict Lock and hard limits operate inside Meridian. The vendor says resting orders above the contract cap, or using blocked entry types, are rejected or cancelled at submission. A market order that slips through may instead be trimmed back to the configured cap. Strict Lock prevents an early in-app release of a fired pause and survives a restart, but does not prevent trading from another device.
- On the PC: the standalone apps can block the broker's order servers in the Windows firewall, so no order leaves that computer. It needs admin rights and lifts when the window ends.
- At the broker: only on Tradovate demo and evaluation accounts, the standalone app sets Tradovate's own liquidate-only lock, which holds even if you close the app or log in from another device. Meridian says funded or live Tradovate, Ironbeam and NinjaTrader accounts have no such broker-side lock.
Guard does not automatically flatten open positions by default; auto-flatten is an opt-in setting. Ordinary trading pauses are designed to block new entries while allowing exits and protective stops. However, NinjaTrader's Disconnect action severs the broker connection and cancels working orders, while the standalone firewall Cut blocks orders from leaving that PC. Traders should understand how each response affects their ability to manage an open position before enabling it.
A trader willing to pick up a phone can usually get around it, so think of Guard as a commitment device for the moments you would otherwise click through, not a guarantee.
Does Meridian work for prop firm accounts?
It depends on the platform your firm provides. Meridian's FAQ says the NinjaTrader 8 add-on works with firms you trade through NinjaTrader 8, naming Apex, My Funded Futures and Take Profit Trader, plus most Rithmic-based programs. Firms that issue Tradovate accounts can use the early-access standalone app. Meridian says TopstepX is a closed platform it cannot run inside.
Guard can mirror your firm's daily loss and drawdown numbers if you enter them as triggers, but Meridian itself says it cannot guarantee you pass an evaluation. Your firm's dashboard stays the authoritative record of any breach, and some firms restrict third-party add-ons, so check your firm's rules first. Meridian also says the software sends anonymized trading and behavior records, linked to a random identifier, for product research; you can opt out by email.
How does Meridian compare with CrossTrade and free risk tools?
We have not tested these tools side by side. Prices are each vendor's published figures on the dates shown.
- CrossTrade: an account manager for NinjaTrader 8 bundled with webhooks and a trade copier; its pricing page listed Standard at $29 and Pro at $49 a month on November 5, 2026. It suits traders who also want automation; Meridian focuses on behavior scoring and enforcement.
- Free NinjaTrader 8 tools: add-ons such as Risk Guardian and RiskMaster enforce daily loss limits, trade caps and lockouts at no cost, and prop firms apply their own limits. If a hard daily loss cap is all you need, try those first.
- Meridian's angle: a score that flags tilt from your behavior before the loss limit trips. Whether that works better than a plain loss limit has not been independently measured.
Can you cancel, and does Meridian give refunds?
Guard is managed through Whop and can be cancelled any time; Meridian says you keep Guard until the end of the paid period and your free Core license keeps working. Its refund policy, last updated September 2026, sets these terms:
- First charge: full refund if you change your mind within 14 days of your first Guard charge.
- Will not run: full refund at any time if Meridian will not install or run on a supported setup meeting the minimum requirements and support cannot fix it.
- Not covered: refunds for trading outcomes or P&L.
- Process: email support with your order number, the issue and your platform and Windows versions; Meridian says it replies within 24 hours and processes approved refunds in 5–10 business days.
The 7 days of Guard on a new free NinjaTrader 8 license are separate from the 14-day money-back guarantee, which starts at your first paid charge. Confirm current terms before subscribing. This summarizes published terms, not a tested refund.
Is Meridian legit?
Meridian appears in the NinjaTrader Ecosystem directory, publishes detailed refund, privacy and risk terms, and openly documents what Guard cannot stop. Those are good transparency signals, but they do not prove how well the software prevents losses.
Independent feedback is thin. On November 5, 2026 we found no Trustpilot page for meridianpsi.com, and the NinjaTrader Ecosystem listing showed no rating or review count. The most detailed public test we found is H2T Funding's 9-day, 25-trade review on a Tradovate prop account. H2T is also a Meridian affiliate. It reported that the baseline flagged oversizing during a profitable run, that it did not consistently see the automated lock behave as prominently as advertised, and that a phone bypasses desktop lockouts.
Verdict: who should consider Meridian Guard?
- Strong fit: Windows futures traders on NinjaTrader 8, or Tradovate evaluation accounts, who know revenge trading or oversizing costs them evaluations and want rules set in advance.
- Try Core only: disciplined traders who just want the behavior score, journal and analytics; Core is free.
- Poor fit: Mac users, TopstepX traders, anyone who needs a lock that holds across every device, and traders who want trade signals or automation.
- Still unverified: PSI accuracy, Guard reliability, support response times and refunds.

Meridian Guard review FAQ
How much does Meridian Guard cost?
On November 6, 2026, Meridian's pricing page listed Meridian Core as free with no card and Meridian Guard at $29.99 a month, billed monthly through Whop. In our November 5, 2026 unpaid Whop checkout, code FUNDINGCODES reduced Guard from $29.99 to $26.99 a month.
Is Meridian free?
Meridian Core is free: the live behavioral score, seven behavioral signals, journal, Intel analytics and 5 years of local session history. Only Guard, the enforcement layer, is paid. Meridian says a new free NinjaTrader 8 license includes Guard for its first 7 days with no card.
Does Meridian work with prop firm accounts?
It works with the platform your firm gives you, not the firm itself. Meridian runs inside NinjaTrader 8 today, which its FAQ says covers firms such as Apex, My Funded Futures and Take Profit Trader, and has early-access standalone Windows apps for Tradovate and Ironbeam accounts. Meridian says it cannot run inside TopstepX. Check your firm's rules on third-party add-ons.
Can Meridian Guard be bypassed?
Yes, in most setups. Meridian says its only device-proof stop is a broker-level lock on Tradovate demo and evaluation accounts through the standalone app. Elsewhere Guard enforces on the Windows PC it runs on, so trading from a phone or second device is outside it.
Does Meridian close my trades?
Not by default; auto-flatten is an opt-in setting on a Trading Pause or Disconnect rule. Ordinary trading pauses are designed to block new entries while allowing exits and protective stops. A NinjaTrader Disconnect, however, severs the broker connection and cancels working orders, and the standalone firewall Cut blocks orders from leaving that PC, so check how each response affects an open position before enabling it.
Is Meridian available on Mac?
No. Meridian says every Meridian app is Windows-only, including the NinjaTrader 8 add-on and the Tradovate and Ironbeam apps. There is no Mac or mobile version.
Did FundingCodes test Meridian?
Not the software. FundingCodes ran an unpaid Whop checkout for Meridian Guard on November 5, 2026 to confirm the FUNDINGCODES price. We did not install Meridian, trade with it, trigger Guard rules, contact support or request a refund.
