$VIX

Hey everyone, fairly new here and still figuring out the nuances of risk management beyond the basics. I'm trying to wrap my head around dynamically adjusting position sizes, especially when implied volatility (IV) for my target equities shifts dramatically. I understand the theoretical link between higher IV and smaller positions to maintain a consistent dollar-risk, but in practice, I find myself either over-correcting or hesitating, missing opportunities. How do experienced traders here handle this? Do you have a specific formula or mental framework you apply when $VIX or individual stock IV spikes/drops significantly, or is it more of a 'feel' developed over time?

Been watching the $NDX run into a potential resistance area around 16200-16300. What's interesting is the relative complacency in $VIX, which remains stubbornly low, hovering around 12-13. Typically, a strong push into new highs or significant resistance often sees a corresponding move, or at least a shift in the implied volatility. The current setup, with $NDX potentially printing higher highs on decreasing momentum (RSI divergence on daily) while $VIX remains subdued, suggests a potential for a sharper correction if support breaks. Are others seeing this as a significant divergence, or is there a fundamental reason for the $VIX's lack of reaction that I might be overlooking? Curious about takes on this.
