This indicator is based on WPR (Larry Williams' Percent Range, %) and its multiple signal lines analysis. Signal lines calculation algorithm is as follows. We have indicator input parameters as source data:
Any period value from the multitude of signal lines is calculated using arithmetic progression:
SignalPeriod(Number) = StartLength + Number * Step,
where the value of Number variable ranges from zero to StepsTotal. Obtained values of the periods are added to the variables array and are used at each indicator tick to get the array of smoothed Larry Williams' Percent Range indicator values. Directions of the current trend for each of the smoothings are calculated and also the number of positive and negative trends for the whole array of WPR smoothed values is determined. The final number of positive and negative trends is smoothed in its turn and used as the indicator lines that form a color cloud displayed with the help of the DRAW_FILLING style class.
A trend direction in this indicator is determined by the cloud color, while its power is determined by the cloud width. You can use the overbought (UpLevel) and oversold (DnLevel) levels that are set in percent value from the indicator maximum amplitude.
Smoothing algorithms can be selected out of ten possible versions:
It should be noted that Phase1 and Phase2 parameters have completely different meaning for different smoothing algorithms. For JMA it is an external Phase variable changing from -100 to +100. For T3 it is a smoothing ratio multiplied by 100 for better visualization, for VIDYA it is a CMO oscillator period and for AMA it is a slow EMA period. In other algorithms these parameters do not affect smoothing. For AMA fast EMA period is a fixed value and is equal to 2 by default. The ratio of raising to the power is also equal to 2 for AMA.
The indicator uses SmoothAlgorithms.mqh library classes (must be copied to the terminal_data_folder\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".

The HLCrossSig for WPR is considered as a trend indicator, since it is intended for "catching" trends. However, it's a pretty complex and informative indicator that allows excluding the psychological and emotional influence from trading.
