Every single day $QQQ dropped 6% or more since its March 1999 inception, 30 total including today, and what happened at the next session's close:

This market action reminds me of that infamous quote by Mark Twain:
“October: This is one of the peculiarly dangerous months to speculate in stocks. The others are July, January, September, April, November, May, March, June, December, August and February.” :-)
$TQQQ Model issuing a SELL (EquityCircuitNextOpen) signal. Exit at tomorrow's open.
Today's BearDip long (63.25) tripped the equity circuit breaker intraday (low 59.22 vs 59.33 trigger). Breaker cancels the breakdown short, so no short even with VIX at 21.2. 7-bar lockout, flat.
My $TQQQ model flashed a bearDip BUY signal at today's close. Entry: Monday's open. Targets oversold rebounds, with room to ride a sustained recovery and rule-based exits to manage risk.
2010-26: 41 trades
- Win rate: 68.3%
- Avg return: +10.9%
- Avg loss: 3.3%
- Max loss: 10.0%
My model is very likely to trigger a bearDip buy signal at today's close, as today's market drop has met all programmed entry conditions. ☠️☠️☠️
My regime indicator told me not to trade, but I broke my rule and ended up in a losing streak, though I cut my size diligently and only took paper cuts. But I am not happy with it. So what should I do? Admit the mistake, don't do it again, and follow my process.
Rule #1: don't blow up.

Model replay:
2018: Nov 13 BearDip -> Nov 14 BearDipBreakdown short.
2022: Jan 19 BearDip -> Jan 21 BearDipBreakdown short.
The flip requires a specific model Exit + confirmation signal. A stop loss alone won't trigger it.
Possible model path:
- Mon Close: Triggered a BearDip Buy Signal.
- If price drops further: Exit long (Stop Loss) and flip to BearDipBreakdown Short.
My $TQQQ trend-following model issues a SELL signal (PeakGivebackNextOpen) after today's close. I'll exit my position tomorrow morning at open.
$66.8 will be my uncle point.
My $TQQQ model triggered a BullDip BUY signal (oversold pullback in uptrend) after Friday's close. The buy order will execute at Monday's market open. Max historical loss for the BullDip family was -12.7% in 2018 (when an 8% hard stop triggered a next-open exit into a gap down).
My swing trading account hasn't made any progress lately. The market regime being in RED says it all. I have only taken one trade in the last two weeks, and it was a loss.

My $TQQQ model triggered a BullDip BUY signal (oversold pullback in uptrend) after Friday's close. The buy order will execute at Monday's market open. Max historical loss for the BullDip family was -12.7% in 2018 (when an 8% hard stop triggered a next-open exit into a gap down).
$QQQ: 5 straight down days, -5.52%.
Since 1999, 7 similar cases: 5-day loss of 4–8%, still above the 140-DMA.
Avg forward returns:
- 1 day: +0.30%
- 1 week: +2.40%
- 6 months: +15.59% (6 complete cases)
Small sample. Recovery can still begin with more downside.
The last precedent of a BullDip making a big move after a FreshHighReversalSHORT in my model was in late 2016 off the ATH. May trigger tomorrow after close if $TQQQ drops.
Historically, this entry family has a 55.6% win rate, with an avg. gain of +21.8% and avg. loss of -4.5%.
