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. Suggested read: arxiv.org/html/1603.06183v1
I don't think people are aware of how aggressive full kelly is. When I "size up" I'm still trading at less than 1/3rd kelly. Those are times when I think my win rate is higher and my winner size is larger.

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.

$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.

FreshHighReversalSHORT can precede deeper corrections. In my model replay, 8/21 completed six-month cases saw QQQ fall 10%+ before regaining its pre-entry high; one reached 20%+ (COVID). A short exit or BullDip entry cannot confirm a bottom. $TQQQ $QQQ

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%.

When @dryan310 talks, I listen.
As the tech sector pulls back this week, so has David Ryan's portfolio exposure. 📉

R/R alone cannot tell you whether a trade has an edge. Expectancy can. A tight stop at a "key inflection point" may improve R/R while reducing win rate. E = P(win) × Avg Win − P(loss) × Avg Loss Until the probabilities and payoffs support it, the "edge" is still just a story.

Covering my $TQQQ short tomorrow morning at the market open based on my model's 4-day exit signal (selling my proxy $SQQQ position in my retirement account).

My best career advice: At every job you should either learn or earn. Either is fine. Both is best. But if it's neither, quit.

First week of GREEN light. Breath is improving. I'm conservatively aggressive.
