5. Forex ascending trend:
Ascending trend channels are a useful tool due to their ability to predict overall changes in trend. As long as prices remain within the ascending trend channel, the upward trend in price can be expected to continue. As soon as prices exceed either trend line forming the channel, however, a strong signal either to buy or to sell is generated. A break through the upper trend line generates a strong buy signal, while a break through the lower trend line generates a strong sell signal.
