Yes, you're right.... in general it's best to be cash into weekends, or at least to not initiate new trades Friday. Since news can break either way.
In this situation, I started small new trades, because I think risk/reward especially for UVXY is favorable here. I just bought 200 UVXY, and less for the others. Buying VIX support, selling into strength has done well. It's near support here.
Big picture I'm anticipating a minor pullback next week esp. if Powell talks rate hikes bc high inflation Wednesday, so I'm putting on small bear starter positions now.
VIX is near 15 support here at 19, had spiked to near 30 recently

My stop is 13.9, just under 14.3 52-week low. Exit target 19. Risk =1.5, reward=4
But mostly I daytrade, in up to 1100 shares at a time UVXY during market drops.
