Detect all possible cross indicators directly from EA

I am building an EA that is currently using Fast and slow MA cross detector with trend slope, but it gives a good amount of false signals

I want to have as many cross indicator detectors as possible:

- Fractal

- Bollinger Bands

- MA

- Hull MA

- ADX

- RSI

- Vortex

etc...

REQUIREMENTS:

1. Those cross detectors must be in separate and unique functions.

2. The timeframe should be detected from the current one

3. No external indicators as resource, you should use native EA functions (IMA, icustom etc)

4. Each detector should have this logic (if red line above green line => sell signal // if green line above red line => buy signal)
