Yeah 24 is key for future trading.
Last hour or so...
Downward Trend below 24, didn't go far, clustered turned up over 24, entry up, 2nd entry, up, 3rd entry stalled, fell back through, short entry worked didn't go far, clustered, back up, ran into top BB line, turned down, lower BB held, entry short went 70pts.
the 6 and 9 worked great for a follow through market like yesterday, but today introduced chop again, then as no way to tell if the future will trend or chop, it falls apart as too simple.
