you get a lot of 10 or 15 min flatlines that dont hold so it's hard to say,6/1.. 7/1 is extreme,hard to hold the ratio, currently 8 /1
shape of chart is important, guess thats what i watch most , extremes not holding ,back in the 80's 3 to 1 was extreme,and was a lot more reliable short than these extremes we get now,so you have to take them into acct, the thieving(picking off the retail) has advanced twenty fold since then, before the lehman,bear stearns, merrill, desolving, big firms actually picked off each other,so they were at risk, today they all seem to be cohesive
That's what has saved me from getting chopped up on days like this. Buy a support, set wide stop, grab a few points, rinse, repeat. Being able to recognize this PA early. Some PA patterns that should create downside follow through fail to do so. Those are early clues Small step like pullbacks make for phenomenal support !
