Hi, is it possible in an indicator, to not plot result until there is a min number of prices. Eg only plot the difference between an average and close price if there is x number of price data.
regards robert

Yes it is possible.
If you want the bar number then use Cum(1) in your code.

Hi Rob
ValueWhen(1, Cum(1)>"X", "Signal") is what I use.

hi, like it, much easier to read and understand. Is it possible to reverse it so signal stops before x points from end?

Hi Robert
Yes it's possible but until someone comes up with a better way it requires two Ref() functions. It goes something like this.
{Inhibit right-side plot by "Shift" bars}
{LastValue() needed for a calculated number}
Shift:=LastValue("number");
Ref(Ref("Signal",-Shift),Shift);
This method makes use of the fact that MetaStock processes innermost functions of an expression first. In this case that's a shift of "Signal" to the right by -Shift bars (delayed if you prefer that terminology), thus discarding "number" bars from "Signal". Then "Signal", now devoid of the rightmost "number" of data bars, is shifted (advanced) to the left. The net effect is that the last "Shift" bars of "Signal" now return N/A rather than the original value. Obviously if the shift value is simply a number then there's no need to wrap it in LastValue().
Hope this helps.
Roy
