An example of flattening market at highs with Fibonacci Channel using High, Low, square root of High*Low, Opening Time and Price and, Closing time and two prices M1 and M4, calculated samely as in Traditional Pivots except, central Pivot = Sqrt(H)*Sqrt(L) instead of, central Pivot = (H+L+C)/3. So, Fib Channel starts at Open Price & Time, and if Bullish then it goes to {[Sqrt(High)*Sqrt(Low)+(High-Low)]-[2*Sqrt(High)*Sqrt(Low)-High]}/2 and if Bearish then to, {[2*Sqrt(High)*Sqrt(Low)-Low]-[Sqrt(High)*Sqrt(Low)-(High-Low)]}/2
The r.lambda, or Pivot Preference, in such an interpretation, (DISCLAIMER: just understanding, limited, mine, opinion) is Bullish if, Risk Reward for the last closed duration(period) was favorable for Buyers. Knowing whether you(as a participant) are Bullish or Bearish is important, as well as what kind of participant you are, as well, i.e. maker or taker.
In any respect, this was a video with a [-BL] Nikkei, and part of a [2BL,+BL,-BL,2Br, +Br,-Br] pivot preference circle
