Good questions, I've been wondering the same myself. This is going to be my personal strategy:
1. Look for stocks in a strong up trend.
2. Wait until they pull back and RSI is oversold.
3. Buy an OTM option with at least 60 days to expiry.
NB: this is just my personal opinion, I'm a newbie so most likely don't know what I'm doing. Just thought I'd share the bare bones of my "strategy".
that would work wonders, however, the biggest issue is to define the uptrend in a clear, objective way.
And, as a corollary, if the uptrend is really strong why not going directly with the underlying?
