If you draw trend lines along both the bottom and top of a share price chart, you will sometimes get a trend channel and you'll sometimes get a wedge shape similar to the one below.

Notice that wedge formations take place over a period of 3-4 weeks. This is because they occur as reversals of intermediate and minor trends. They will not be seen, except in unusual circumstances, as reversals to a major market trend.
