The usual reason for indicators and explorations
returning different numbers is because the exploration is fed less
data that what is available to an indicator on a chart. There are at least 25 MS
functions that won't return accurate values if the Explorer is set to "Load
Minimum Records". Ideally you should set that value to the same number of bars
that you'd normally open for a chart. In practice you can get away with a lot
less. Any function that uses an exponential moving average requires about 5
times as much data as the nominal Periods parameter. ADX and RSI are typical
examples but there are many others. Functions using an Nth parameter might not
get a true Condition signal and when that happens an N/A result is the most
likely outcome.
If the Explorer is set to "Load Minimum Records" it
will generally load 30% more data than the greatest Periods parameter in the
explorations code. This works fine for the majority of functions, but not all.
I find that there exists, at times, a difference between what an
indicator shows on a chart and what will appear in an exploration. Can
any one suggest a possible cause for this occurence. Thanks for your
consideration.
