What about:
Buy = ... AND BarsSince(Cross(Close, MA(Close, 15)) <= 3;
Or would that fail due to comparing an array (BarsSince) to a scaler
(3)? If that's the case you could wrap it in a zero offset Ref as:
Buy = ... AND Ref(BarsSince(Cross(Close, MA(Close, 15)), 0) <= 3;
I haven't tested this. But, assuming that it does work and that
Bill's suggestion works, it would boil down to personal preference.
All depends on which you find more "readable".
