| Issue | Impact | |-------|--------| | Slower on USB 2.0 | Database loading, large backtests, and chart refreshes lag significantly. USB 3.0/3.1 or external SSD recommended. | | No native portable version | You must manually create it (copy installation + use a launcher like Cameyo or PortableApps.com launcher, or set UseRegistry=0 in config). | | Plugin path restrictions | Some 3rd-party data plugins (e.g., IB TWS, eSignal) hardcode paths to C:\Program Files\. May fail on portable setup. | | Shared drive conflicts | If two instances open same database from a network/cloud drive, database corruption occurs. | | No auto-update | Updating AmiBroker requires manually copying new files over the portable folder. | | Windows security alerts | Some antivirus flags portable launchers as suspicious because they run without formal installation. |
