Like I said in my post it is based on the megaphone and / or broadening top pattern. If u buy into the theory behind them then the setup is there.
thanks -- notice how you can superimpose the 'sample' megaphone almost perfectly over the current Dow action. edge or not, it will work or it won't, by chance or by algo-fulfilling prophecy, who knows. jmho.
Time for eduation.... If the broadening formation was hitting the top and you had a downtrend, you got a potential edge. If the broadening formation was hitting the bottom and you had an uptrend, you got a potential edge. All else, no edge.
there are with trend and against trend moves,against trend(reversal) usually happens at supp and res and with trend in between
