## Volume afl for Amibroker

• Volume Lines for VSA from AmiFiles
•  The code here was found on traderguider web site....
•  A 30 period moving average can be used to determine if Volume is greater than average or less than average.
•  if you put a 2.0 standard deviation of that 30 average on the chart as well,
•  then you could call all Volume histogram bars greater than that line High.
• You could also place a 3.0 standard deviation of the average on the chart AND call all
• Volume histogram bars greater than that Ultra High Volume. This is basically what TG does.
