You might look at the MRO function. It finds how far back something
was last true. If you look for the thing that you don't want to find
and it doesn't occur in the interval you test, then it didn't occur.
Something like the following should do it. Check the exact behavior
of the MRO function to see if the limits are correct for what you
want.


XAve = XAverage(Close, 25);
BSE = BarsSinceExit(1);
If prevtrade = -1 and  MRO(XAve > XAve[1], BSE, 1) = -1
   then CanShort = TRUE
   else CanShort = FALSE;
