Yes, it's possible to extract RSI and MACD values for a product, and they should be available for all products as they're the standard analysis fields.
below is an example to extract these values
import eikon as ek ek.set_app_key("xxxxxxxxxxxxxxxxxxxxxxxxxxx") macd_rsi, err = ek.get_data(["FB.O","AMZN.O","AAPL.O","NFLX.O","GOOG.O"], ["TR.MovAvgCDLine1.date","TR.MovAvgCDLine1","TR.MovAvgCDLine2","TR.MovAvgCDSignal","TR.RSISimple14D","TR.RSIExp14D","TR.RSIWilder14D","TR.RSISimple30D","TR.RSIExp30D","TR.RSIWilder30D","TR.RSISimple9D","TR.RSIExp9D","TR.RSIWilder9D","TR.RSISimple3D","TR.RSIExp3D","TR.RSIWilder3D","RSI_14","RSI_30","RSI_7"])macd_rsi
