usage: zlma [-l N_LENGTH] [-o N_OFFSET]

The zero lag exponential moving average (ZLEMA) indicator was created by John Ehlers and Ric Way. The idea is do a regular exponential moving average (EMA) calculation but on a de-lagged data instead of doing it on the regular
data. Data is de-lagged by removing the data from "lag" days ago thus removing (or attempting to) the cumulative effect of the moving average.

optional arguments:
  -l N_LENGTH, --length N_LENGTH
                        Window lengths. Multiple values indicated as comma separated values. (default: [20])
  -o N_OFFSET, --offset N_OFFSET
                        offset (default: 0)


Examples:
- To display the ZLEMA with a window length of 20 for a stock: stocks/load <SYMBOL>/ta/zlma
- To display the ZLEMA with a window length of 30 for a stock: stocks/load <SYMBOL>/ta/zlma -l 30
- To display the ZLEMA with multiple window lengths, 20 and 50, for a stock: stocks/load <SYMBOL>/ta/zlma -l 20,50
- To display the ZLEMA with a window length of 20 and an offset of 5 for a stock: stocks/load <SYMBOL>/ta/zlma -l 20 -o 5
- To display the ZLEMA with a window length of 30 and an offset of 10 for a stock: stocks/load <SYMBOL>/ta/zlma -l 30 -o 10
- To display the ZLEMA with multiple window lengths, 20 and 50, and an offset of 5 for a stock: stocks/load <SYMBOL>/ta/zlma -l 20,50 -o 5
