I measure my trading goals against investment opportunities in the real world, simply because if I can't beat those then I might as well put my money with them.
For example, the highest investment return I've found happens to be my 401k which is on fire, with +50% returns this year so far. While I cannot put my money in that plan (retired early), my high challenge is to match or beat it but I'd be satisfied with an after-tax +30% return, which is a low 6 figure income.
I'm a basic stock trader, sometimes day trading, sometimes holding weeks to get my numbers. I'm under no pressure to close at the end of the day. But I have a high win rate and low value losses that I attribute mostly to inexperience. 80% of my trades are on a single stock while the remaining 20% is split among 2-3 others. So far I've been lucky although I've also missed some opportunities, but I'm on target for beating my goals.
