The trial version of Tunnel ABC Pro V1 is designed for evaluation purposes only and includes the following restrictions to differentiate it from the professional version: Asset Restriction: The indicator is strictly limited to the USDSGD currency pair. It will not initialize or display data on any other symbol. Account Type: This version functions exclusively on Demo Accounts. It is automatically disabled on Live/Real accounts to ensure safety during the testing phase. Locked Configuration: All visual and technical parameters (colors, line thickness, Fibonacci levels) are hardcoded. Users cannot modify the settings menu in this version. Visual Watermark: A permanent "Trial Mode" watermark and an initial disclaimer are displayed on the chart to identify the version. Full Feature Access: While it includes the core ABC projection and Fibonacci logic, advanced customization and multi-asset flexibility are reserved for the PRO version.
