Quote from 5Pillars:
A 380 tick chart is good too........ 19.5 X 19.5 = 380.25 (380 is good enough ).
Also the 330 tick chart (33.0 X 10.0 = 330).
Don't ask me why 19.5 and 33 are VERY significant numbers.
You are drowning me in detail 5P.
If you are refering to ES ( which is the only instrument that I know), the tic bar is going to be more relevant to the time of day than some magic set of numbers.
At 09.31, you could not tell a 317 from a 330 tic bar.
