The indicator calculates running total of linear weighted returns. It transforms rates into integrated and difference-stationary time series with distinctive buy and sell zones. Buy zones are shown in blue, sell zones in red.

Parameters:

• period - number of bars to use for linear weighted calculation; default value - 96;
• smoothing - period for EMA; default value - 5;
• mode - an integer value for choosing calculation mode: 0 - long term trading; 1 - medium term trading; 2 - short term trading; default value - 0;
• price - price type to use; default value - open;

Best signal to buy - when the line becomes blue (crosses zero upward), best signal to sell - when the line becomes red (crosses zero downward). Also buy on corrections if the indicator is blue, and sell if it's red.
