Chart the multi-day ( ). Normally, the is tracked for the current day, from the first bar of the day (regular or extended session). The shows the current value of:
-> sum(hlc3 * , barsForDay) / sum( , barsForDay),
-> where 'barsForDay' is the total number bars that have elapsed during the day for the chart interval.
The multi-day version tracks the for N days back, by averaging the previous N - 1 day bars and the current for the current bar (chart interval).
This is very different that simply using a , since the closing values are used for the historical day bars. The results are interesting for intraday trades... especially for values of 1, 2, 3, 4, and 5 days.
