Hi BW

If you plot a forward-referenced value on a chart, Ref(C,+5) for example, then you will notice that the plot stops 5 bars before the righmost data bar. In other words the rightmost bar and the 4 bars preceding it will return N/A for the forward-referenced CLOSE. This is exactly the effect that you are getting with the Explorer. MetaStock cannot plot indicators or whatever beyond the last bar of data, and for every bar that you project into the future MetaStock will generate an N/A result. If the Explorer cannot return a valid value for the last bar explored then it has to return an N/A (just as a chart for the above example returns an N/A for the last bar).

Rather than trying to force Metastock to do what it cannot and will not do, you need to think about what result you require and then make sure that that result is accessable as at the last bar of data. If you can figure that out on a chart (a valid result on the last data bar) then the code should generate the same result when used in the Explorer. Be aware, however, that you might need to tell the explorer to load more data. Using the Minimum Records option will cause problems - don't assume that because your charts show 1000 bars that the Explorer will load the same amount of data. Minimum Records is not your primary problem here but it could be adding in a confusion factor that tends to mask the real problem.
