$RBLX

Been diving into how the pros really think about position sizing, and it's more nuanced than just the standard 'risk 1-2% of your account' rule of thumb. While that's a good starting point, it doesn't account for volatility or the actual probability of your setup. For instance, risking the same dollar amount on a $RBLX scalp with a tight stop versus a wider stop on a longer-term $USDCAD swing feels off, given the different volatility profiles and potential move sizes.

What I'm realizing is the critical piece isn't just a fixed percentage of capital, but rather calculating the dollar value of your stop loss first, and then working backward to determine how many shares or lots you can take to keep that dollar risk within your comfort zone. This seems to allow for more consistent risk per trade, regardless of the instrument's price or daily range. Anyone else approach it this way, or have other methods that factor in the actual market conditions more dynamically?

I'd put the odds of $RBLX revisiting its day low of $47.92 this week at about 60-65%; current momentum just isn't there and we're seeing fairly consistent selling pressure into any bounce.

$RBLX is moving hard: -5.45% on the day, now at 49.64.

Day range: 49.63 – 52.54.

Been looking at a few names recently, mostly some mid-caps like $RBLX and $DKNG, that I got into with what I thought was good conviction on a breakout. Problem is, they just haven't moved. Not down enough to hit my stop, but certainly not up either. They've just been range-bound for weeks, effectively tying up capital that could be used elsewhere. I'm hesitant to cut them at a small loss, or even break-even, because I still believe in the setup long-term, but the opportunity cost is starting to weigh on me. At what point do you guys decide to just pull the plug on a position that's not performing, even if it hasn't technically hit your defined stop-loss?
