Moving Averages (SMA and EMA)

Plot the simple moving averages (SMA) and/or exponential moving averages (EMA).
The length of the lookback period and the type of moving average can be changed in the inputs tab of the indicator.
Line-weight and colours can be edited in the style tab of the indicator.

The default is to plot the SMAs using a length of 20, 50, 100 and 200.
