QQQ after 4 days of red candles is reaching new support level?

After breaking the double head last week, the QQQ retraced this week to a possible new support level at 171. If the QQQ rises the coming week, a second daily higher low (from the February correction) would signal buys. Neverteless, the bull market has extended for so long (10 years aprox.) that a significant correction could arrive any time soon.
