Fibonacci Retracement Tool and Coding

Hi cTrader team, 

When plotting  the Fibonacci retracement levels on charts, adding an option to remove the trendline while keeping the Fibonacci levels visible is a functionality that you should look into. I have even tried coding a Custom Fibonacci Tool to handle that problem. i think you guys should look into this issues to implement optional trendline visibility in both a custom Fibonacci indicator of the one built in your ctrader platform.

in a sell scenario one could argue its useful but i a buy scenario its completely useful and just adds clutter to the charts. Either way an option to enable or disable should be available 

Could you please:

1. Review the current implementation of the Fibonacci Retracement Tool.
2. Add an option to toggle the visibility of the trendline independently of the Fibonacci levels.
3. Consider adding this as a user-configurable setting in the properties panel.
4. Provide developer documentation or code examples for implementing these features when creating custom Fibonacci  indicators.
5. Include any relevant API methods or properties that would help manage Fibonacci objects programmatically.
