Built by prop traders. Running live. Trusted with our own money.

Trade once.
Calamari handles the rest.

Calamari keeps every MT4 and MT5 account correctly sized, synchronized, and within its individual limits — so you can execute one decision and have it applied correctly across your accounts.

Under the hood: your Tentacle hosts your master terminal and all receiver accounts. FX Blue Personal Trade Copier runs locally on that Tentacle — sender and receiver terminals communicate locally within the same Tentacle, avoiding an external cloud-copying relay. Sub-second local copy propagation, with per-account lot sizing, symbol filters, and risk limits applied automatically.

You trade from your phone or laptop. The master account runs on the Tentacle. Calamari does the rest.

Calamari does not provide signals, strategies, or account-management services. You retain full ownership of every trading decision. Calamari is a tool for traders managing their own accounts — not a service that manages accounts for you.

The problem

Running multiple MT4/MT5 accounts
is a second job.

Traders who manage multiple prop accounts face a set of operational problems that have nothing to do with trading.

🖥️

Multiple terminals, multiple tabs

You are managing 4–7 MetaTrader windows. Each one needs to be open, logged in, and monitored. One crash means a missed copy.

📐

Manual lot sizing every time

A $10k account and a $50k account need different lot sizes for the same trade. Doing this manually under pressure is a mistake waiting to happen.

🚨

No consolidated view

You have to tab between accounts to see your total exposure. There is no single screen showing all your positions, P&L, and risk at once.

😴

Terminals crash when you sleep

MT4/MT5 disconnects at 2am. You wake up to find a terminal that has been offline for six hours and missed three copy events.

⚠️

Drawdown limits creeping up

You are watching multiple accounts manually for daily loss and max drawdown. One bad day and you miss the threshold on one account.

🔧

Infrastructure is your problem

You provision a raw server. You install the terminals. You configure the copier. You diagnose failures. You own every migration and recovery risk.

None of these are trading problems. They are infrastructure problems. And infrastructure problems have infrastructure solutions.

See how Calamari solves this
How it works

Simple in concept.
Serious in execution.

You trade on your device. Calamari distributes those trades across your MT4 and MT5 accounts — sized correctly, filtered correctly, monitored continuously.

Copying

Three steps. One platform.

1. You trade on your device. Your phone, your laptop, MT4, MT5 — however you trade. Your designated master account remains connected through a terminal on your Tentacle. You may trade that account normally from your phone or computer. When the Tentacle terminal detects the resulting trade, the local copier distributes the configured instructions to the receiving terminals.

2. Calamari copies those trades. To your MT4 and MT5 accounts — all running on your dedicated Tentacle, all sized and filtered per-account. Sender and receiver terminals communicate locally within the same Tentacle, avoiding an external cloud-copying relay. Broker execution speed, fills and slippage remain dependent on the broker, market conditions and network connectivity.

3. You focus on entries and exits. Calamari handles distribution, sizing, filtering, monitoring, and recovery. Calamari continuously monitors supported Tentacle and terminal health signals while the service is operational, including nights and weekends.

Trust & Security

Your accounts are our priority.

✓

Calamari does not inspect, analyze, copy or reuse your trading strategy. Staff do not have standing access to your Tentacle. Temporary support access requires authorization and is logged.

✓

We do not copy your trades to any other account.

✓

We do not sell trading data or disclose it for advertising, signal generation or use by other traders. Limited data may be processed by infrastructure and service providers solely to operate Calamari, subject to contractual confidentiality and security obligations.

✓

Each customer receives an isolated Tentacle with allocated CPU, memory and storage. Customers do not share an operating-system environment or trading-terminal installation.

✓

You can revoke access instantly.

✓

Full transparency: you see everything happening on your dashboard in real-time. Full security details →

The infrastructure stack

Five layers of infrastructure.
One monthly price.

Every layer below exists so you can focus on your edge — your read on the market, your timing, your entries — and nothing else.

🛡️

What “Monitor & Protect” actually means

Monitoring — Live Now
  • • Real-time drawdown alerts as limits approach
  • • Daily loss threshold warnings
  • • Copy failure notifications
  • • Terminal crash detection and auto-restart
  • • Incident diagnosis and failure reporting
Enforcement — Roadmap
  • • Block new trades when limits are reached
  • • Automatically reduce position size
  • • Pause individual receiver accounts
  • • Close positions on breach threshold

Enforcement features will be clearly labeled when available.

🖥️

Layer 1: Your Tentacle (Managed Windows Appliance)

Each customer receives an isolated Tentacle with allocated CPU, memory and storage. Customers do not share an operating-system environment or trading-terminal installation. Always-on, managed, and monitored. Up to 7 MT4/MT5 instances, any blend. We handle the infrastructure so you never have to think about it.

Windows ServerAlways-onFully managed
📡

Layer 2: FX Blue Trade Copying

FX Blue Personal Trade Copier runs as an EA directly inside MT4/MT5. Sender and receiver terminals communicate locally within the same Tentacle, avoiding an external cloud-copying relay — sub-second local copy propagation. We configure and manage it for you.

FX BlueSub-second local copyIntra-Tentacle
⚖️

Layer 3: Intelligent Sizing & Filtering

Per-account rules via FX Blue copier receiver filter: lot scaling based on account size and risk%, symbol blocking, max lot limits. Each receiving account gets its own configuration — sized correctly, filtered correctly.

Lot scalingSymbol filtersPer-account rules
🛡️

Layer 4: Monitor & Protect

Two distinct functions: Monitoring delivers real-time alerts and warnings — drawdown approaching limits, daily loss thresholds, copy failures, terminal crashes. Enforcement actions (blocking trades, reducing size, pausing receivers, closing positions) are on the active development roadmap and will be clearly labeled when available.

Alerts (live)Warnings (live)Enforcement (roadmap)
📊

Layer 5: Full Visibility Dashboard

Built-in dashboard replaces third-party monitoring tools — no extra EA needed. One screen. Every account. See balances, open positions, P&L, and account health across your MT4/MT5 accounts in real time. Full analytics, no tab-switching.

Real-timeBuilt-in analyticsNo extra EA

LiveView

See your MT4/MT5 terminals in real time directly from your browser. No RDP client needed. Watch your charts, verify your trades, and troubleshoot — from your phone if you want. Your screens, anywhere.

Browser-basedNo RDP neededMobile access
🔌

Tentacle API

Every Tentacle exposes a RESTful API. Customers get programmatic access to query positions, account data, and trigger actions. Build your own integrations directly against your infrastructure.

Tentacle Agent

Our lightweight agent runs on your Tentacle and connects it to the Calamari network. It enables remote management, trade data streaming, and health telemetry — all encrypted. The nervous system of the whole operation.

MT4 & MT5 Terminal Compatible

Calamari is technically compatible with standard MT4 and MT5 terminals. Firm, program and account eligibility is reviewed during onboarding. No special integrations or prop firm partnerships required.

Why FX Blue — not API-based copiers

API-based and cloud-based copy services introduce latency, have outages, and when they fail, your trades do not copy. FX Blue Personal Trade Copier runs as an EA directly inside MT4/MT5. Sender and receiver terminals communicate locally within the same Tentacle, avoiding an external cloud-copying relay. This is the only approach we trust with our own money.

🦑

Ten tentacles. One brain.

Just like a real squid, Calamari extends its reach across your accounts simultaneously — monitoring, copying, recovering, and reporting — all from a single intelligent core. Up to 7 MT4/MT5 instances per Tentacle. You stay in control without being everywhere at once.

The managed-service layer

How the master-terminal model works

“Your designated master account remains connected through a terminal on your Tentacle. You may trade that account normally from your phone or computer. When the Tentacle terminal detects the resulting trade, the local copier distributes the configured instructions to the receiving terminals.”

📱
Trade from anywhere
MetaTrader allows simultaneous logins. You can place trades into the master account from your phone, laptop, or any device. The terminal on the Tentacle detects those trades and triggers the copy.
🔢
Terminal limit includes master
The master terminal counts toward the stated limit. Up to 7 total terminals per Tentacle — including the master. For example: 1 master + 6 receivers.
🗂️
Multiple master accounts
Multiple master accounts can be configured for traders running different strategies across separate account groups. Each master drives its own set of receivers.
⚡
Manual changes persist
If you manually alter a receiver account, the change persists until the next copy event overrides it. Be aware of this when making manual adjustments.
🔌
Disconnect behavior
If the master account or broker connection disconnects, copying pauses until reconnection. The watchdog detects this condition and alerts you.
📊
Broker execution is independent
Sub-second local copy propagation describes the intra-Tentacle copy speed. Broker execution speed, fills and slippage remain dependent on the broker, market conditions and network connectivity.
Who Calamari is built for

Designed for a specific trader. Not for everyone.

Calamari is right for you if
  • ✓You trade Forex or CFDs on MetaTrader 4 or MetaTrader 5
  • ✓You manage approximately four to seven MT4/MT5 accounts that you own
  • ✓All accounts execute from the same strategy — you want them synchronized
  • ✓Each account has different sizing requirements that need to be applied automatically
  • ✓You want one place to see all accounts, positions, and health at once
Calamari is not right for you if
  • ✗You trade futures, options, or non-MT4/MT5 platforms
  • ✗You have a single account and do not need trade copying
  • ✗You are looking for trade signals or a strategy to follow
  • ✗You want someone else to manage accounts that belong to other people
  • ✗You need a PAMM, MAM, or third-party account management structure

Calamari is a tool for Forex and CFD traders managing their own same-owner MT4/MT5 accounts from a common execution strategy. If that is you, it was built for you specifically.

“
We did not build Calamari to sell software. We built it because we needed it to trade better. We still run our own accounts on it every day. That is the only endorsement that matters.

What happens after you sign up

From signup to live
in six steps.

We handle the technical setup. You review and approve before anything goes live.

📋
Step 01

Tell us your accounts and programs

Share which prop firms you are trading, which accounts you want connected, and your basic risk parameters. We verify MT4/MT5 compatibility for each program.

🔍
Step 02

We verify compatibility and provision your Tentacle

We confirm your accounts are compatible with MT4/MT5 and provision your dedicated Tentacle. Each customer receives an isolated Tentacle with allocated CPU, memory and storage. Customers do not share an operating-system environment or trading-terminal installation.

⚙️
Step 03

Terminals installed, credentials entered securely

We install and configure your MT4/MT5 terminals. Trading-platform credentials are encrypted before storage in Calamari's segregated credential vault. Credentials are never stored in plaintext. Administrative access is restricted, time-limited and logged. Customers can rotate credentials at any time. Credentials are permanently deleted upon service cancellation.

🗺️
Step 04

Master and receivers mapped, risk settings reviewed

We configure FX Blue: your master account is set as sender, each prop account as a receiver with its own lot-sizing rules, symbol filters, and risk limits. Sender and receiver terminals communicate locally within the same Tentacle.

✅
Step 05

Test trade performed — you approve production activation

We run a test copy to verify the full chain works end-to-end. You review the results and give the go-ahead before we activate production mode.

🚀
Step 06

You are live — monitor everything from one dashboard

Your setup is active. Every account, every position, every copy event — visible in real time from your Calamari dashboard. Calamari continuously monitors supported Tentacle and terminal health signals while the service is operational, including nights and weekends.
