Playing options is really tortureous.

You see the market accurately, and the underlying price is indeed going in the direction you predicted, but time waits for no one - Theta decays and gnaws away your premium day by day, and finally the account is still green.

What's even more amazing is that sometimes the direction is right and the time window is quite sufficient, but the market suddenly stops moving, and IV (implied volatility) dives directly. Vega's losses instantly engulf the floating gains, and you can only watch as options become waste paper.

To put it bluntly, making options is not just about betting on ups and downs. You have to manage both time costs and volatility risk, but many people enter the market with the intention of simply giving directional exposure. As a result, he found himself fighting with the Greek alphabet legion - Delta, Theta, Vega each had to be stared at, and one exploded without looking.
