Trade copier + TradingView webhooks for NinjaTrader 8
Trade it once — by hand or by alert.
Filled on every account.
Meridian turns your TradingView alerts into NinjaTrader orders, and copies every trade — yours or your strategy's — from one account to every account you run in under a millisecond. Then it reads each one back to prove the copy landed, fixes any that drifted, and keeps every prop account clear of its drawdown floor, the news, and your own bad days.
- ✓Trade copier — every follower sized, copied and checked.
- ✓TradingView webhooks — alerts become orders, with brackets, scale-outs and risk sizing.
- ✓Live Console — place NinjaTrader orders from a live, updating chart, in any browser.
The trial has every feature and needs no card. Windows + NinjaTrader 8, any broker connection. Set up in about twenty minutes.

What Meridian is
Meridian is a trade copier for NinjaTrader 8. It processes signals from TradingView or your own strategies and replicates the resulting orders across every account you run — then verifies each fill, corrects drift, and protects every position.
It does not generate signals or trade recommendations. The signals are yours; Meridian copies them. The alerts it sends are about its own work — a guard tripped, a level reached, a red folder minutes away — never an opinion on what to trade.
Copying
Every account copied. Every copy checked.
Most copiers send the order and hope. Meridian copies to every follower in under a millisecond, sized for each account — then checks every account against its leader and fixes any that fell out of step. We call it reconciliation, and it happens before you would have noticed.
- ✓Sized for each accountAll plans — ratios, micros, contract caps and scale-outs.
- ✓Read back, then repairedAll plans — a missed fill is caught and corrected, with the leader's exits attached.
- ✓Graded, trade by tradePro — every follower's copy time, slippage and misses.
- ✓Told when a copy goes wrongPro — a copy not placed, held by a rule or filled well off the leader, within a minute.
- ✓The whole desk at a glanceAll plans — what every account holds, market by market, flagged the moment one is out of step.
TradingView webhooks
Your TradingView alerts, traded in NinjaTrader.
Paste one private address into a TradingView alert and every signal becomes a real NinjaTrader order — about 30 ms from alert to working order — then the copier takes it to every follower. No bridge software, no server to rent, no port to open on your PC.
- ✓Brackets from the alertAll plans — stop and target in ticks, points or dollars, up to five scale-out targets, break-even and a trailing stop.
- ✓Sized by riskAll plans — send a dollar or percent risk and Meridian works out the contracts at your stop.
- ✓In step with your strategyAll plans — an exit never opens a reverse position on an account that's already flat.
- ✓Late alerts refused, not chasedAll plans — exits always go through.
- ✓Every alert accounted forAll plans — received, placed or refused with the reason, timed to the millisecond.

Live Console
Place NinjaTrader orders from a live chart — anywhere.
A trading front end for NinjaTrader in your browser. The chart moves with every trade NinjaTrader sees, your position and working orders sit on it, and an order you place goes to your leader — so every follower copies it, under every one of your rules.
- ✓A chart that updates in real timeAll plans — fed by your own NinjaTrader, so there's no second data subscription.
- ✓Trade on the chartAll plans — right-click (long-press on a phone) to buy or sell at that price in one click, or put a take-profit or stop-loss on the open position; drag a working order to move it, or right-click it to cancel.
- ✓Brackets before you sendAll plans — pick a stop and target and see them on the chart first, with a second target, break-even and a trailing stop.
- ✓A key for every actionAll plans — buy, sell, close, reverse, flatten and stop to break-even (your followers' stops too, each at its own entry), with a confirm step unless you turn on one-click trading.
- ✓The facts behind the clickPro — levels and confluence zones on the chart, the session and every timeframe in a row above it, your bracket's reward-to-risk and what a stop-out would leave each account.
- ✓From any deviceAll plans — the same console on a laptop away from the trading PC, or on your phone.
Prop accounts
Keep every evaluation alive.
Accounts are lost to the drawdown floor, the news and the trade after three losses. Meridian enforces your limits on the PC itself — and a restart is not a way around them.
- ✓Drawdown floor enforcedAll plans — flattened and locked at your buffer.
- ✓Live trailing roomPro — points to the floor for every open position; entries halved, then stopped, as it nears.
- ✓Payout-zone lockPro — an earned balance is not traded back.
- ✓Exposure caps and no hedgingPro — across correlated markets and every account.
- ✓A max stop resting at the brokerAll plans — protected even if the PC dies.
- ✓News and tilt guardsPro — entries held around red folders, a pause after losses, no sizing up after a loser.
- ✓Evaluation tracker and Prop DeskPro — target, days, consistency, costs and payouts.
Review
Replay it. Practise it. Trade it again.
Replay any past session with your real fills on it — and practise it until the second go beats the first.
- ✓Session replayAll plans — every fill at its own price, each trade's P&L where it closed, on the contract that traded that day.
- ✓Practice tradingAll plans — paper-trade the replay and compare with what you really did.
- ✓Rule simulatorAll plans — would a loss limit or a trade cap have helped? Your real trades say.

Running the desk
Two PCs. One desk. No babysitting.
Set the routine up once: the copier starts and stops on schedule, and with Twin Desk a second PC keeps step with your main one — for when your broker logins live in separate NinjaTrader installs.
- ✓Twin DeskPro — your second PC follows your main PC's positions, each account at its own ratio, with its own guards. Signals only ever go to the main PC.
- ✓Schedules and saved setupsPro — start at the open, flatten at the close, switch layouts in one click.
- ✓Your PCs onlyMax — Twin Desk never reaches another trader's account.
AI assistants
Ask your desk anything. Act with a tap.
Connect Claude, ChatGPT or any assistant that supports MCP to your own desk. It answers from your live accounts — and when you ask it to trade, the request comes to your phone before anything happens.
- ✓Plain-English answersMax — evaluation room, today's P&L, why a copy missed, what's on the calendar.
- ✓Your tap on every tradeMax — orders, flattens and pauses wait for Approve, and still pass every risk rule.
- ✓Your limitsMax — read-only or trading links, chosen accounts and sizes, revoked in one click.

Why Meridian
Not an order repeater. A desk that keeps itself in line.
Copying an order is the easy part. Meridian is built for what happens after it: whether every account really holds what it should, whether the next order would break a firm's rule, and whether you can act when you are nowhere near the trading PC.
Checked, not just sent
After every trade each follower is read back against its leader. A partial fill, a rejected order or a manual trade is put right with the leader's stop and target attached — instead of a log line and a follower left off-side or unprotected. Working orders are mirrored, and every copy is graded for speed and slippage.
How copying works →Prop rules enforced before the damage
The trailing floor is followed live, with the room left for every open position in points. As it shrinks, entries are halved and then stopped. A payout-zone lock keeps an earned balance, the consistency guard stops a day from getting too big, and exposure caps and a no-counter-positions rule work across all your accounts.
Prop risk management →In control without a remote desktop
The whole desk in any browser, phone included: positions, P&L and a Panic button that flattens every account. Alerts arrive within seconds, escalate if the copier drops mid-trade, and Telegram can pause or flatten. Twin Desk keeps a second PC in step, while TradingView signals only ever reach your main one.
Control from anywhere →Automation you can check first
TradingView alerts become bracketed NinjaTrader orders — stops, scale-outs and risk sizing from the message — with the contract month taken from NinjaTrader's own rollover schedule. Check an alert in the sandbox before it is live, and connect an AI assistant that can read your desk and asks for your tap before it trades unless you exempt an account.

What a copier usually does, and what Meridian does
The news guard, the exposure caps, Telegram, escalation when the copier dies mid-trade, the speed and slippage figures and the daily report come with the higher plans. Everything else in this table is on every plan — including a push to your phone when the copier goes down. Compare the plans.
Isolation
Your signals are structurally invisible to other traders
Every account gets its own webhook address with its own secret, minted on the server and shown only to you, and signals reach exactly one PC — your main one — so a second machine can never compete for your orders. It is not a policy you have to trust — it is how the addressing works.
How isolation worksGetting started
Three steps, about twenty minutes
Your account starts its trial the moment you create it, and the dashboard walks you through the rest with a checklist — linked PC, a leader with followers, alerts that reach you, a test signal, a stop at the broker.
-
STEP 01
Create your account
A name, an email and a password. No card, no call with sales. The trial starts straight away with every feature on.
-
STEP 02
Install the AddOn and sign in
Download it, import it with NinjaTrader's Tools → Import, and sign in from its window. That PC is linked to your account and reconnects on its own. No server to rent, nothing technical to configure.
-
STEP 03
Drag your accounts into place
Drop followers under your leader on Copier Setup, set each one's size and rules, and trade. Using TradingView? Paste your webhook URL into the alert and signals route too.
Straight answers
Before you start a trial
Is copying allowed by my prop firm?
Most futures prop firms allow copying between accounts you own; some limit how many accounts or forbid copying between different people. That rule is the firm's, so check their current terms. Meridian copies only between accounts on your own NinjaTrader — and if your firm forbids hedging, it can refuse counter positions (long one index future, short another) on one account or across all of them.
What if my PC or internet dies mid-trade?
With a max stop loss set, every copied position already has a stop resting at the broker, so it is protected without your PC. You also get a push, Telegram or email alert when the copier goes quiet, and when it comes back it checks every account against its leader before it does anything else.
Does it need a VPS?
No. The AddOn runs inside NinjaTrader on the PC that holds the account, and the dashboard is a website. You do need the PC awake and NinjaTrader running while you expect to trade.
Which broker connections work?
Any connection NinjaTrader itself supports — sim or live, Rithmic, AMP, Interactive Brokers, Databento or a simulated account. Meridian copies orders into accounts; it does not care who the broker is.
What happens if my leader disconnects?
Whatever you chose: hold, flatten, or pause and report — globally or per follower. Meridian also warns you when a connected leader's P&L has been frozen long enough that the link is probably dead, so "silent" stops being an option.
What if a signal arrives late?
Its age runs from the moment Meridian received it — so time spent waiting for your PC to reconnect counts against it. A market entry older than your limit is refused as expired, journalled, and offered to you for a deliberate re-send instead of chasing a move that already happened. Exits are always placed, however late; being late to a close is never worse than staying in.
How do I know the service itself is up?
Probes check the signal path end to end every few minutes during the session and email the operator when a state changes; the current state of every component is on a public status page. The account store is backed up nightly with each copy verified, and a weekly drill boots the real service against the newest backup — "backed up" is proven by "restored".
Can I run it on two PCs?
Signals always go to one PC, so two machines never place the same order. With one PC on your plan, signing in on another moves the account there and signs the old one out. A plan with more PCs adds them for Twin Desk — they follow your main PC's positions and never receive signals themselves.
Does it place its own trades?
No. It only copies what your leader account does, and corrects a follower that has fallen out of step with it. It has no strategy of its own and no opinions about when to enter.
Is this a hosted service or software I own?
You run the copier on your own PC; the dashboard is the control plane and the delivery path for your alerts. Your accounts and keys are yours — the service holds no broker credentials.
What happens when the trial ends?
Nothing is charged — there's no card to charge. The copier stops routing until you pick a plan, and your settings, journal and history stay where they are, so carrying on is one step. Every plan keeps the full copier and all the safety systems.

A trial with every feature, no card, set up in about twenty minutes. Run it in sim first if you like — if it doesn't tell you something about your copying you didn't already know, it hasn't earned the subscription.
