Williams R% indicator on COST

The Williams R% makes the read of the trend line changes easier. This chart for example, demonstrates that each time the indicator goes over the top in whichever direction it follows, a change of the trend line may occur.
Here, in point A goes from a upper trend followed by the indicator to a down trend immediately the R% shows that the trend changes is happening. The moment the R% shows that the trend is followed then we can place our order.
