The price patterns also explains the demand and supply but it gives us the characteristic of the market with the entry and exit. some of the major price patterns are double top and bottom, cup pattern ,flag pattern, head and shoulder, triangle pattern etc., If there are two tops formed with equivalent points then we can say a double top is formed and if there is two bottoms with Volume high then its double bottom. The duration is 20 days to 1 month. The line chart pattern appears like shoulder, head(with high top) and a shoulder formation is called as head and shoulder. Head and shoulder mainly happens during the distribution or accumulation of stocks from strong hands. Condition for bearish trend are Left Shoulder with high volume, tallest head, shoulder with low volume formation with 3 months duration. Volume is high at left shoulder and low at the right shoulder. Likewise we use flag and triangle patterns.
