Quote from riskarb:
No touches[touches] cannot invert gamma modality, either paired or singles. You can mitigate the gamma risk with long-dated positions, but the gamma goes vertical near the strike, regardless of time to expiration. They cannot be replicated with vanilla options. With luck, the SEC will see fit to stop babysitting the US investor and allow for retail-trading of exotics.
You might want to consider trading digitals if you can find a retail shop. SocGen's clickoption doesn't carry credit risk, but their pricing isn't very competitive and you'll need to be a EUR-citizen to play. BoM is really your only option unless you establish a PB with serious cash.
