This screen finds stocks whose price has just crossed below the first support level (S1), calculated as two times P minus the previous high. Pivot points are calculated from the previous month's high, low and close: the pivot point P is their average, R1 and R2 are resistance levels above it, and S1 and S2 are support levels below it. A move below S1 shows unusual weakness, and S2 becomes the next target.
