CFD sizing: The forgotten risk lever?

It feels like everyone focuses purely on market direction and leverage ratios when discussing CFD risk, almost to the exclusion of position sizing. I've seen traders with solid analytical frameworks blow up accounts because their sizing wasn't dynamic or tied to their conviction level on the trade. A low leverage ratio on a massive position can be riskier than higher leverage on a tiny one, especially when you're looking at things like $EM fluctuating between 1.195 and 1.2. Is it just me, or do we underplay the power of proper position sizing as the primary risk control in CFDs? Change my mind.
