trends:
trend changes first in lowest possible time frame (its a fact) and then it changes on successive higher time frames (inclusive of eod, weekly and monthly etc). tick is the lowest possible time frame.
normally we read in various books that we should use higher time frames and take entries on lower time frames. or trade in the direction of higher time frame trend. but trend changes first in lowest possible time frame. Wyckoff used to maintained point and figure charts of intraday to take trades from eod. still today in pure wyckoff method 1 or 5 minute time frame is used to plot point and figure chart for eod trading.
my trading approach/call it theory, is that we should also trade the current time frame from lower time frame trend (only day trading, dont know whether it works well on eod or not as dont trade or see those charts).
hopefully i will further share my this particularly day trading theory/approach.
