Trending beyond either bias signal, after becoming too late to trigger, is “no-bias trending” that requires retracing to the broken bias signal.
-The requirement is determined when the bias window begins lapsing, if price is then beyond the signal.
-Often its 10:15/1:20 print is also retraced.
-The requirement can be mooted by exiting the bias window much further away, beyond its bias target.
Similarly, a bias-up or bias-down window should not retrace its bias signal during the window. Like no-bias trending, its probe would likely be only temporary until retracing.
