Time Frames: 5min to 60min. This will also work on Daily Chart, by setting "DaystoExpire" to 21

Options:

• Use Daily Data to Calculate StdDev HV (default), otherwise use the charts Time Frame
  
• Lookback = number of days/periods to calculate stddev of HV (21 by default)
  
• Annual = number of trading days in a calender year (252 by default)
  
• Days to Expiry = number of days for the life of this option ( for auto calculation
  this is 1 for intraday, 21 for daily and annual when chart TF used)
  
• Settlement Source = close price by default, can use another source.
  
• Settlement Volume Weighted Average Length = by setting this to >1 then an average
  is used for settlement.
