It does work with explorer. However there is no "periods" component to BarsSince() so unless the
value that would be returned is less than the number of bars being explored the result will be N/A.
Setting up an exploration using "minimum" periods is very likely to cause a problem. With this
setting the number of bars used will be determined by the greatest "periods" value of all other
functions in the exploration. Best practice is to use the same number of bars as you load for each
chart. If this slows things down too much (as it will with formulas using PREV) then settle for an
acceptable number between 100 and 500 bars.
You need to set the number of periods at least 5 times greater than the greatest "periods" setting
of any EMA being used to get an accurate EMA value anyway.
If you load 10 or 20 bars on a chart you'll tend to get exactly the same "failure" of BarsSince() as
you get with the Explorer, the reason being that the reference event is off the radar.
