Try something like this:

lv = L < LLV(Ref(L,-1), 251);
lvb = IIf(lv, Cum(1), BarCount+1);
lbars = LLVBars(lvb, 90);

Array "lv" has a one at every new 252 bar low. "lvb" sets every such
indication to its bar number (starting from 1) and BarCount+1 for
every other bar (so that they're higher than every other value).
"lbars" will return the number of bars since the lowest bar number in
the last 90 bars, which will match the first 252 bar low during that
period.

Note that I haven't tried this though, so can't guarantee it works.
