Library "lib_math" a collection of functions calculating without history operator to avoid max_bars_back errors
mean(value, reset) Parameters: value (float): series to track reset (bool): flag to reset tracking @return returns average/mean of value since last reset
vwap(value, reset) Parameters: value (float): series to track reset (bool): flag to reset tracking @return returns vwap of value and volume since last reset
variance(value, reset) Parameters: value (float): series to track reset (bool): flag to reset tracking @return returns variance of value since last reset
trend(value, reset) Parameters: value (float): series to track reset (bool): flag to reset tracking @return [slope, correlation, stddev, y1 , y2] where slope is the trend direction, correlation is a measurement for how well the values fit to the trendline (positive means ), stddev is how far the values deviate from the trend, x1 would be the time where reset is true and x2 would be the current time
