Can someone please tell me if there is a Better Sine wave indicator or Hilbert Sine wave (with S/R lines) available for NT8 in nexusfi (like eminiwatch) ? The only sine wave I find was built for NT7. Here is one from ninjatrader forum but unfortunately it is also made with older version.

Key Points:
Complexity: This implementation is more complex and attempts to more accurately represent the Hilbert Transform. It calculates a continuous sine wave representation of the price action, useful for identifying market cycles.

Testing and Optimization: This indicator should be thoroughly tested and possibly optimized for the specific asset and time frame you are trading.

Expertise in Signal Processing: The Hilbert Transform is a complex topic in digital signal processing. If you are not familiar with these concepts, you might need further research or consultation with a specialist.

Indicator Characteristics: The Hilbert Sine Wave indicator is used to identify market cycles and should not be used in isolation. It's typically more effective when combined with other indicators and analysis techniques.

Remember to test this script thoroughly in a simulated environment before applying it to live trading, as it's a complex tool and can have significant implications on trading decisions.
