Is it possible to fetch Calculated Indicators (RSI, ATR) or Strategy Data directly?

I want to know if the API offers any endpoints to fetch pre-calculated technical indicators or strategy-specific data to save processing time on my end.

My specific questions are:

1. Computed Indicators: Does the Fyers API return values for indicators like RSI, Bollinger Bands, or EMA directly? Or is the API strictly limited to raw OHLCV data, requiring us to calculate indicators locally (using libraries like pandas or talib)?

2. Strategy Data: Is there any endpoint that provides "Global" strategy signals (e.g., "Top Gainers," "Volume Shockers," or "Trend Signals") via the API?

3. Option Chain / OI: apart from the Quote API, is there a historical endpoint specifically for Open Interest (OI) analysis?

If these are not natively available via API, is there a recommended "Best Practice" library you suggest for Python integration to handle these calculations efficiently?

Thanks in advance!
