If you’re long EUR/CHF, it might be worth considering a square-up before the weekend just in case those stops get smashed on Monday morning. I’m sure you’ll be able to get back in at similar levels on Monday morning?
Another question worth considering, is whether the SNB have credit limits in place to handle that amount of turnover? On a Monday morning? Too risky for me this pair, best avoided, sit back and wait for trading opportunities imho.
