There is no objective set of criteria to identify this. Rather, ask yourself whether you're in the mode of「每每捉頂捉底失敗,或等待RP之際」. If your answer is a "yes", it is that kind of moment for you.
What if, what if, just at the moment when you've just opened a long strangle/straddle (lc + lp), the market action displays a trough-turn-uptrend (peak-turn-downtrend), would you blame yourself for not having opened a simple directional sp/lc (sc/lp)?
This is the classic paradox of a trader: Is the market trendy, range trading, or just reached the TRP?
