Your essentially looping through an array of points looking for the biggest and smallest peaks and waiting for the delta either side them to go >= 6dB. When it does you grab the biggest peak between the -6dB points. Rinse and repeat.

double lastValue = 44;
List<double> peaks = new List<double>();
for (int i = 0; i < trace.Length; i++)
{
  double currentValue = trace[i];

  // waiting for the delta (so, diff between this and last value?)
  double delta = currentValue - lastValue;

  // either side them to go >= 6dB. (both sides = do for + and -)
  if (Math.Abs(delta) > 6)
  {
    // When it does you grab the biggest peak between the -6dB points. 
    DoMagic();
  }

  // now the current value becomes our "last read value" before looping again
  lastValue = currentValue;
} // Rinse and repeat.

What this means is that the window could grow dynamically. By setting a physical window width we can limit the max search window +/- either sode of the located peaks.
