No one knows for sure - intentionally or mistakenly, Larry Williams - one of the greatest traders of our time and the creator of the classic study of WPR (Williams' Percent Range,% R) - has laid such properties in his creation, that under certain market conditions the use of the indicator is not just risky but dangerous.
An inherent property of oscillators is "sticking" of the line under trend market. The danger lies in the fact that in that case Williams' Percent Range gives multiple false signals for orders opening.
The indicator which can handle this problem is an upgraded WPR_VSmark, which clearly demonstrates the direction of price movement of the trading instrument at the current and related to the current timeframes. "Sticking" line shows existence of trend, and synthesis of signals of different timeframes lets to avoid entry into the market in the wrong direction.
A little left to do is to learn how to professionally use the modified indicator WPR_VSmark together with a set of powerful tools of trading systems of early forecasting at the SRP Department of the Academy of Trading Masterforex-V.
