Hammer, The first sign of the beginning Ascending wave:
Hammer shows that the war between buyers and sellers, at the beginning of the day sellers could create significant reduction in price, with their high investments. But when the price had come to the lowest extent of it, many of buyers have entered with more investments than sellers. And again they could increase the price close to what it was at the beginning of the day or may even more. And at the war that was between buyers and sellers, the buyers have been the winners of the day, and the market is largely in control of them. Thus, the possibility of further price increases in the coming days is enormous.
example: picture Shows, currency pair of EUR/USD -0.31% in a 30 minutes time frame.
At the beginning, by increasing investments of sellers, the price became to 1.16886 But in this range with the arrival of large buyers to the market and overcome to turnover of shopping on sales transactions, the price increased again. Sellers could increase the selling price due to the amount of demand from buyers. The starting price is may be at 1.17495 but it increased by the end of the day to 1.17578.
As what can be seen, after forming Hammer , an Ascending wave started and the Price have increased more.
