You can find some anecdotal examples / opinions on trading returns

A few questions though…
How are you defining “good” above ?
In general, the returns would depend on the amount of risk one assumes, right? (riskier the positions, larger the potential returns, and chances of larger losses as well.)
It will also be interesting to know whether it is even logical to expect such a target percentage
in any of the 3 types of trades you mentioned.
IIUC, the market sentiment and volatility would determine the returns,
and the returns observed over a certain period (say the last year),
might not be a realistic target for another period (say the coming next year).
