We are going to sell our SQ (Square) at tomorrows opening, or if it opens up, trail a stop at today’s low of $61.48
Currently our WWG (Wyckoff Wave Growth Index), as well as QQQ is nearing overbought Technometer readings.  SQ seems to have slowed up its rally here, and under performing, so we want to sell our position that we bought at $58.96 tomorrow at the opening.  If it does gap up, you could watch it early but do not let it fall below today’s low at $61.48
