Here is Gary`s commentary:
Since the Confluence indicator returned several "states" (bull, bear, grey, and zero),
he modified the return value a bit:
-9 to -1 =
-0.9 to 0.9 = "grey" (and zero)
1 to 9 =
The "grey" range corresponds to the "grey" values plotted by Dale's indicator, but
they're divided by 10.
