An entry gets most of a trader's attention, but the exit plan is what actually determines the outcome of a trade. Deciding both a stop-loss and a profit target before entering — not during the trade — is one of the simplest, highest-impact habits in options trading.
Why Exits Should Be Set Before Entry
Deciding an exit while a position is open, in real time, means deciding it under pressure — with money already at risk and emotions already engaged. That's exactly when judgment is least reliable. Deciding the exit before entry, while thinking clearly, removes that pressure from the equation entirely; the plan already exists, and the trader's only job is to follow it.
Three Ways to Define a Stop
There's no single "correct" way to define a stop-loss — different methods suit different trading styles:
- Percentage of premium. Exit if the option loses a set percentage of its value (for example, 50%). Simple and consistent, but doesn't account for the underlying stock's actual price action.
- Underlying price level. Exit if the underlying stock breaks a key technical level — like the support levels covered in support and resistance explained — regardless of exactly how much the option's premium has moved.
- Dollar amount. Exit once a trade's loss reaches a fixed dollar figure, tied directly to the position sizing decided in position sizing for options traders.
Many traders combine two of these — for example, a dollar-amount stop as the hard limit, informed by where the underlying's key level sits.
Setting a Profit Target, Not Just a Stop
An exit plan isn't only about limiting losses — it also means deciding, in advance, when to take profits rather than letting a winning trade ride indefinitely and hoping for more. A common approach is a fixed reward-to-risk ratio (aiming to make roughly two or three times what's being risked), so the target and the stop are set together as a single, coherent plan rather than two separate decisions.
A trade with a well-defined stop but no profit target often turns into a trader second-guessing a winning position in real time — exiting too early out of fear, or holding too long out of greed. Deciding both sides of the trade up front removes that in-the-moment guesswork.
Time-Based Exits Are an Options-Specific Rule
Options add a dimension stocks don't have: time decay. A price-based stop alone can miss the risk of a position that's simply running out of time to work, even if the underlying hasn't hit a technical stop level. Many options traders add a time-based rule — for example, exiting or reassessing a position by a certain number of days before expiration, regardless of price — specifically to manage this extra risk.
Mental Stops vs. Hard Stops
A hard stop is an actual order placed with a broker that executes automatically. A mental stop is a level a trader has decided on but must manually act on when it's hit. Hard stops remove the risk of hesitation but can be trickier to set precisely on less liquid options; mental stops offer more flexibility but require real discipline to actually execute when the moment comes — which is exactly the discipline problem covered in why most options traders fail.
Putting a Full Exit Plan Together
Before entering any trade, a complete exit plan answers three questions: where's the stop, where's the target, and is there a time-based rule that overrides either one? Tools like ScalpClock's Exit Assistant are built specifically to help define this plan mechanically, ahead of time, rather than leaving it to be decided in the moment.
