Question about managing 'known unknowns' in EM FX

I've been dipping my toes into EM FX, primarily $ZAR and $TRY, and it's humbling. I'm trying to get a handle on the political/geopolitical overlay, which seems to swing these pairs around more violently than, say, $EURUSD on an ECB statement. My question is, how do you seasoned EM traders factor in these 'known unknowns' – the stuff you know could happen, but is inherently unpredictable? Is it wider stops, smaller position sizes, or just a tacit acceptance that you're going to get whipsawed sometimes?
