how to find value of RSI at each Fractal

Hi, I am trying to find value of RSI at each fractal. Following indicators I tried to use:

            rsi = Indicators.RelativeStrengthIndex(Source, 14);
           fractals = Indicators.Fractals(2); // Fractals with 1 bar on each side
 

Though I can iterate over rsi values e.g.  Print("RSI" + i + ":" + rsi.Result[i]);

But then I don't know how to relate them to fractals which I think I can get using like:

fractals.DownFractal.ElementAt(i);

fractals.UpFractal.ElementAt(i);

Though I can find fractals using Bars,  by coding myself , in that case, I will know which past Bar is a peak/bottom of a fractal but still I am not sure what's the value of RSI on each bar/candle.

 When I was looping on RSI values, first value comes as NaN i.e. at index 0 and next 5 values comes back as 0 i.e. upto index 5. Only “rsi.Result.LastValue” seems to return correct value, but then that's only the last value.

So, is it possible to know what's the value of RSI on each past Bars?

Thanks.
