Makes no sense. If you want to trade, then trade. Timeframe is an illusion to make you feel comfortable. There is no difference between trading daily or yearly.
Also, the market can still go up in a recession, war or whatever.
The issue with more frequent trading is that you are paying more in transaction fees, and that it gives you more chances to make irrational decisions that result in lower returns.
That's not an "issue" but more like why you shouldn't trade in the first place. My point is, long-short timeframe are no different if you don't know the direction it is moving.
