Volume (D)EMA

A simple yet configurable indicator that shows recent traffic volumes.
The time period is specified as weeks/days/hours/minutes, not as bars.
Set the volume period to non-zero if you want to use a generalized double EMA instead of plain.
The "ratio" option will show the size of the current volume compared to the average volume as computed for the specified time period; say hello to fat tails and goodby to "standard" and "normal" and "average". With the "together" option, it compares the current volume to the both sides together (buy+sell), otherwise it compares it to just its respective side.
