Call Ratio Spread

One call bought at a lower strike, two sold at a higher strike, same expiration: a call ratio spread entered for a small debit or a credit, and net short an option.

The exposure is worth stating plainly. Only one of the two short calls is offset by the long call, so a sustained rally above the upper strike produces losses that keep growing with the stock. Each leg is priced from bid and ask, and the expiration payoff grid shows the peak at the short strike and the slope beyond it.
