Does anyone here swing trade SPY?

I realize most people hold indexes and add either dca or when they see it fall here and there.

Does anyone here wait till it hits a certain level, put some money in and then wait till it hits some resistance and sell?

I mean I realize taxes, but a profit is a profit and you can also do it in a ROTH for no taxes.

I guess you could do it with any index really but I know SPY has a lot of key levels that would make it easier to trade over a few days.

So basically you wait till it's “low”, add some money, then sell quick when it reaches some resistance.

Then rinse and repeat. To me this is better than holding long in this wacky market.
