Managing Winning Trades: When to Take Profit
Knowing when to walk away from a good trade is its own skill, and most people get it wrong. Here is why closing a winner early, around half its max profit, usually beats holding for the last dollar.
- Why the last dollar of profit is the most expensive to chase
- The 50% rule: closing a winner around half its max profit
- How to close a credit spread to lock in the gain
- Why taking profit early lets you win more often
Your trade is working. You are up money, the stock is behaving, and now you face the question that trips up almost everyone: do you close it and take the win, or hold on for more?
Most people hold. They watch a solid profit, decide they want the whole thing, and wait. Then the stock turns, and the gain they already had slips away. The skill nobody teaches is knowing when enough is enough. It turns out there is a simple, almost boring answer, and it makes a real difference.
Why You Don't Wait for the Last Dollar
Profit on a trade does not arrive evenly. The first half tends to come quickly and safely. The second half is slow, and you have to risk the entire position for weeks just to squeeze it out.
Think about a credit spread you sold for a $370 credit. Once it has dropped to where you could buy it back for $185, you are sitting on $185 of profit, half the maximum, often in a fraction of the time. To get the rest, you would hold for weeks more, exposed to the full risk the whole time, all to chase a shrinking reward.
That is the whole idea behind the 50% rule: when a winning trade has captured about half of its maximum profit, close it. You give up the hardest, riskiest half of the reward in exchange for locking in the easy half and freeing yourself to do it again.
The 50% Rule in Action
Let me make it concrete with the bull put spread you learned earlier. You sold it for a $370 credit, and your max profit is that full $370 if it expires worthless.
A couple of weeks in, the stock has held up nicely and the spread has lost most of its value. You can now buy it back for $185. So you do: you pay $185 to close, and you keep the $370 you collected minus the $185 you just paid, which is $185 of profit, locked in. The trade is over, the risk is gone, and your cash is free.
Why Closing Early Lets You Win More
There is a hidden bonus. When you close a winner early, you do not just lock in profit, you free up the capital and the risk slot it was using. That lets you put on a fresh trade.
A trader who takes the easy 50% and resets can run several clean trades in the time it takes someone else to grind one position to the finish. More turns, less risk per turn, and far fewer winners that slipped away.
When I was advising clients, the hardest lesson was that a profit is not real until you take it. The ones who learned to close winners early, almost mechanically, slept better and kept more. The ones who always held for the last dollar gave a lot of it back.
- Profit comes unevenly: the first half is fast and easy, the second half slow and risky.
- The 50% rule: close a winner once it has captured about half its max profit.
- You close a credit spread by buying it back for less than you sold it.
- Closing early removes all remaining risk and frees your capital to trade again.
- A profit is not real until you take it. Many trades give back gains that were already there.

Three quick questions to lock it in. Pick an answer and the explanation shows up right away.
You sold a spread for $370 and can buy it back for $185. What is your profit if you close now?
You keep the $370 you collected minus the $185 you pay to buy it back: $185, about half the maximum, locked in early.
Why give up the second half of the profit?
The last half of the reward takes weeks of full risk to capture. A late turn can erase the gain you already had. Trading the slow half for zero risk usually wins over time.
What is the hidden bonus of closing a winner early?
A closed trade returns your capital and your risk slot, so you can put on a new position. More clean turns beats grinding one trade to the very end.
Bottom Line
Taking profit is a skill, and the simplest version of it is the 50% rule. When a winner has handed you about half of its maximum, close it, bank the easy money, and free yourself to trade again. You give up the slow, risky half of the reward, and in exchange you take all of the remaining risk off the table. Do that consistently and you will keep far more of what your trades give you.
