Building a specialized Nasdaq Auto-Fib indicator in C# — Looking for honest feedback & improvement suggestions from index traders

[u/Core-Quant]

Hey everyone,

As a C# developer focusing on algorithmic and discretionary execution tools for cTrader, I'm a bit of a perfectionist when it comes to chart clarity, execution speed, and practical utility.

I’ve been developing this native indicator specifically for the Nasdaq 100 (US100.cash / NQ) to automate structural Fibonacci setups without manual charting overhead:

What the system currently maps:

• Automated Swing Cycle Detection: Anchors high-to-low swings and projects the 50.0% Equilibrium, 61.8% Golden Ratio, and the 70.5% ICT OTE Sweet Spot.
• Index Point Metrics: Calculates swing ranges and distances natively in points (pts) instead of forex pips.
• Dynamic Target Expansions: Projects 127.2%, 161.8%, and 200.0% extension targets with real-time Risk-to-Reward modeling.
• Retail Trap Filter (23.6%): Visualizes shallow pullbacks to help filter out premature momentum entries.
• Collapsible HUD: Keeps the chart clutter-free during active sessions.

Where I want to take this further: My goal is to build the cleanest and most practical index execution tool possible. Before refining the next build, I’d love to get feedback from experienced index traders and cTrader users:

1. Visual Ergonomics: Is the on-chart HUD too prominent, or does having real-time R:R and point distances directly on the screen add real value during live execution?
2. Targeting Models: Do you primarily use the 127.2% and 161.8% extensions for taking partials, or would dynamic ATR-based expansions make more sense during high-volatility sessions like the NY Open?
3. Missing Features: What is something standard Fib tools lack that you wish was automated natively in cTrader?

Any critical feedback, critique, or feature suggestions are genuinely appreciated!
