New here, looking at risk management - specifically position sizing vs. account size

Hey all, been following a few threads and finally decided to register. I'm trying to get a handle on risk management beyond just 'don't blow up your account.' I've heard the usual 1-2% per trade rule, which I'm mostly sticking to. But when the market is particularly choppy, say $SPX is bouncing all over the place, or $EURUSD has some big news event creating huge swings, my stop-loss ends up being further away to avoid being instantly whipsawed. This means my position size has to shrink significantly to maintain that 1-2% risk. It feels like I'm trading peanuts even when I have a decent conviction. How do you guys balance a wider stop with still taking a meaningful position without overexposing?
