Thoughts on managing risk for $NIKKEI futures swings overnight?

Hey everyone, still trying to get my feet under me with the Asian sessions, specifically $NIKKEI futures. I've been paper trading it and seeing some decent intraday moves, but the overnight holds are where I'm tripping up. The volatility can be wild, and my usual R:R framework feels a bit stretched when the market can gap significantly.

For those of you actively trading $NIKKEI or similar Asian indices, how do you adjust your position sizing or risk parameters for trades you might hold through the close and into the next open? Are there specific metrics you look at that differ from your day-trade setups? My main concern is getting caught in a large adverse gap and blowing through my intended stop before I can even react. Any insights would be appreciated.
