Moving Averages (gotta plot them all!)

The length of the lookback period and the type of moving average can be changed in the inputs tab of the indicator.
The type of moving average can be selected from:

• 
  
• Simple Moving Averages
  
• Exponential Moving Averages
  
• Symmetrically Weighted Moving Average
  
• Weighted Moving Averages
  
• Volume-weighted Moving Averages
  
• Moving average used in RSI
  
• Arnaud Legoux Moving Averages
  

The source of prices to use in the calculation can be selected from:

• close
  
• open
  
• high
  
• low
  
• (high + low + close + open)/4
  
• (high + low)/2
  
• (high + low + close)/3
  

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.
