Check it out on your platform, look at the chains 1 week out and see the options volume and OI, the difference even between them and the ones that expire tomorrow. You will see SPY options 1 week DTE with over 100k OI trading 30k volume. Those are the contracts to be on. View the theta and delta for both 1 week DTE and one that expires tomorrow. You'll see why you can't trade 1-3 DTE. It's just not "safe" IMO
