If you mean 25% above the low:

C >= 1.25 * MAXH252 AND C > AVGC200 AND AVGV5 > AVGV195.5

If you mean 25% of the range above the low:

STOC252 >= 25 AND C > AVGC200 AND AVGV5 > AVGV195.5

If you mean 80 above the low:

C >= 1.8 * MINL252 AND V < V5 AND FAVG(V, 5) < AVG(V, 5)

If you mean 80% of the range above the low:

STOC252 >= 80 AND V < V5 AND FAVG(V, 5) < AVG(V, 5)

The volume interpretations are quite different based on the slightly different wording used. If the results aren't what you want, you might want to provide some additional clarification.
