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". --- In [email protected], "longarm61" <[EMAIL PROTECTED]> wrote: > > Thanks Bill.
