One call, bought outright. The debit paid is the whole of the risk and it is known before the order goes in, while above the strike the contract gains with the underlying and nothing caps it. People reach for it when a move is expected inside a definite window and they want the worst case written down in advance rather than discovered later. The difficulty is that a call has to be right twice — about which way and about by when — because time value drains whether or not the move arrives. Set the strike and the days here, then read the breakeven: it is the number that says how big the move has to be.

This is a single-leg ticket: one call, one strike, one expiry — the simplest order this tool builds. Strikes trade in fixed increments (often $1 or $2.50 near the money on a liquid name, wider further out), so the strike a model prefers is not always the strike you can fill. Liquidity concentrates at round strikes and monthly expiries; a strike between them can carry a wider bid/ask that eats into the edge a backtest assumed. Check open interest before sizing a position larger than the visible depth can absorb.

Sizing and account notes

Position size against the premium at risk, not against the notional the call controls — a $725 call on 100 shares of a $580 stock is often sized as though it were a $58,000 position, which overstates the loss it can actually produce. Many traders scale into a directional call across two or three tranches rather than one, buying more if the thesis is confirmed rather than committing the full size on day one. Wash-sale rules can apply if a losing call is closed and a similar one reopened within 30 days — relevant mainly to repeated short-dated trades on the same name.

Common mistake. The common mistake is buying a strike so far out of the money that even a correct call on direction never clears it before the premium decays to nothing — the breakeven, not the current price, is the number that matters.
