The idea of the fifth dimension:
•Buyers are weaker on the "b" bar in comparison to the "a" bar. It proves that the "b" bar's high is lower than the "a" bar's high.
•Why are sellers stronger on the "b" bar? The reason for this is that new information came to the market (on the picture it is shown as a dashed square) and changed the balance.
•If buyers become stronger and raise the market (refer to the "c" bar) to the "a" bar's high, this means that the market balance is changing and it may be a first signal to make a deal within the fifth dimension.
Bar "b" is the base bar:
•Base bar for a signal to buy is the most recent bar whose high is lower than the preceding bar's high ("b" bar in the figure above). It may be the current bar; for example, "b" bar when there is no "c" bar yet.
•Base bar for a signal to sell is the most recent bar whose low is higher than the preceding bar's low (it may be the current bar).
Materials on this is a bit sketchy.
I will appreciate any help.
