In the fast-paced world of algorithmic and technical analysis trading, flexibility is no longer a luxury—it is a necessity. For decades, Amibroker has stood as the gold standard for charting, backtesting, and trading system development. However, a recurring question among its global user base remains: Can I run AmiBroker from a USB stick?
The answer is a resounding yes. This comprehensive guide dives deep into the concept of Amibroker Portable, exploring how to create it, the legal and technical nuances, performance trade-offs, and why this setup might be the most powerful tool a traveling trader can possess.
The magic of a portable AmiBroker is plug-and-play. However, market data updates constantly. If you use the portable drive on Monday on PC-A, then on Tuesday on PC-B, you need the latest EOD or intraday data.
Solution: Self-Contained Data Feed. Configure your portable AmiBroker to download data directly from a cloud source (e.g., Yahoo Finance via the AmiQuote plugin, or a 3rd party API like Alpha Vantage). As long as the portable PC has an internet connection, the database updates itself.
Alternative: Two-way sync.
Use a tool like FreeFileSync to mirror your USB's Data folder to a cloud folder (OneDrive) when you get home. But if you are truly portable, keep the data on the stick. amibroker portable
Step 1: Install AmiBroker Normally Install AmiBroker on your local C: drive using the default installer. This writes necessary Registry keys and installs core components.
Step 2: Locate the Installation Directory
Navigate to C:\Program Files\AmiBroker (or wherever you installed it).
Step 3: Copy the Entire Folder to Your USB Drive
Copy the AmiBroker folder to E:\PortableApps\AmiBroker (where E: is your USB drive).
Step 4: Copy the Application Data
This is the critical step many miss. AmiBroker stores user data (layouts, favorites, databases) in:
%APPDATA%\Amibroker (usually C:\Users\[YourName]\AppData\Roaming\Amibroker) Amibroker Portable: The Ultimate Guide to Trading on
Copy the contents of that Roaming folder into your USB drive’s AmiBroker folder, inside a subfolder named Data or User.
Step 5: Use Relative Paths via amibroker.reg
On your USB drive, create a text file named amibroker.reg with the following content:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Tomasz Janeczko\Amibroker]
"DataPath"=".\\Data"
This tells AmiBroker to look for user data relative to its own executable.
Step 6: Launch Test
Double-click AmiBroker.exe from the USB drive. If it asks for registration, enter your key (it will save the license file locally in the portable folder). This tells AmiBroker to look for user data
Fix: Ensure your host machine has the required Visual C++ Redistributables installed. A portable app cannot install system-level runtimes. Prefer using 32-bit AmiBroker on portable drives for maximum compatibility.
To maximize your portable environment, include these in the root folder:
*.dat files created on foreign PCs.Many corporate or university computers lock down the ability to install new software. Because a portable AmiBroker doesn’t write to Program Files or the Registry, it often runs without triggering administrator password prompts.
