WL stands for Wim Lievens, a Belgian trader with over 20 years trading experience.
WL Bars are based on price movements not on time. A candle is drawn only if the market goes up or down a certain number of points/ticks/pips. This puts time out of the equation. Only movement and range are relevant.
WL Bars combine the advantages of range (detail), renko (clarity) and heikin-ashi (direction) candles. Analyzing charts for opportunities is much easier. Since all bars have the same size entering the market or money management becomes substantially better.
