Jav, I noticed you were posting wolf wave projections the other day. Have you tried the indicator for the MT4 platform, the 15 min time frame seems to be fairly accurate with it.
One of the best books I've read is by Bryce Gilmore and is called "An Introduction to the Methods of WD Gann". Its a very short book but he doesn't waste any time getting right to it.
He gives a great synopsis with the methods of squaring price and time.
Price units in a trend equal time units in a trend Base price equals time units to a new change in trend Prior price range equals time units to a new change in trend Prior time units equals next price range to a new change in trend Current price equals time units from a prior change in trend
