Quote from hardrightedge:
Upside Gap N Trap stats last 6 months for Monday openings (QQQ):
6/02 TRAP
7/07 No Trap
7/14 No Trap
8/18 No Trap
9/02 No Trap
10/13 No Trap
11/03 No Trap
11/24 No Trap
12/01 No Trap
The stats make sense because Monday is (1) usually bullish
and (2) usually not a reversal day
