Common Income Trading Mistakes
You now have every tool a premium seller needs: the trades, the management, the framework for picking strikes and dates. The traders who struggle from here rarely fail from a lack of knowledge. They fail from a short list of repeat mistakes. Here they are, with the fix for each.
- The handful of mistakes that still catch experienced premium sellers
- The fix for each, drawn from everything you have learned in this course
- Why discipline, not knowledge, decides who lasts as an income trader
- A send-off to sell premium with confidence
Here is something reassuring and humbling at once: traders who struggle at selling premium rarely fail from a lack of knowledge. By this point, you know the trades, the management, and the framework for picking strikes and dates. They fail because of a short list of mistakes that keep catching sellers of every experience level, again and again.
This final lesson gathers those mistakes in one place. None of them will be new to you, because the fix for every single one is something you have already learned in this course. The income trader's job from here is not to learn more. It is to stop making these few errors, consistently. Let me lay them all out.
The Mistakes That Still Catch Premium Sellers
Read this list slowly. Each mistake on the left has quietly ended good accounts, and each fix on the right is a lesson you already hold.
The Big Three, Up Close
A few of these deserve a closer look, because they cause the most damage.
Chasing the richest premium is the beginner's trap that never fully goes away. The fattest credit on the chain always sits closest to the stock price, which also means the highest chance of being tested or breached. Selling for the biggest number instead of the best balance of odds and reward turns a strategy that should win most of the time into a coin flip you happen to get paid slightly more for losing.
Selling through earnings tempts even seasoned sellers, because implied volatility swells right before the announcement and the premium looks unusually rich. That richness is not a gift, it is the market pricing in the exact danger you are being paid to take on. A move big enough to blow through a strike that looked perfectly safe the day before is common on earnings day, and no amount of premium fully compensates for stepping in front of it uninformed.
Oversizing undefined risk is the quiet account-killer of this entire course. A strangle sized the same way you would size a defined-risk spread is a very different bet: without a wing capping the loss, one large move can do many times the damage a capped trade ever could. The fix is not to avoid strangles, it is to size them smaller from the start, before a loss ever forces the lesson on you.
Discipline Is the Edge From Here
Notice what every fix in this lesson has in common. Not one of them is a clever new strategy or a secret indicator. Every single one is a piece of discipline you already learned somewhere earlier in this course.
- Weighs the odds before chasing a big credit
- Only sells puts on stocks they'd be glad to own
- Skips known events before expiration
- Sizes undefined-risk trades smaller
- Rolls to improve a trade, never to deny a loss
- Sells the strike with the biggest number, odds unchecked
- Panics at assignment on a stock they never wanted
- Sells rich premium into a known event and gets caught
- Sizes a strangle like it has a cap when it does not
- Rolls the same broken trade again and again
From here, your edge is not knowing more. It is applying what you know, consistently, especially when a fat credit or a tempting story makes the discipline feel unnecessary. When I was advising clients, the traders who lasted at selling premium were never the ones who found some hidden edge. They were the ones who sized right, respected events on the calendar, and took the loss when a trade had clearly broken instead of arguing with the market.
- The richest premium sits closest to the price, meaning the highest chance of being tested. Weigh the odds.
- Only sell puts on stocks you would be glad to own; assignment should never be feared.
- Skip selling premium through earnings or major events, the rich credit is pricing in real danger.
- Undefined-risk trades like strangles need smaller size than capped spreads, not the same size.
- Roll to improve a trade you believe in. Take the loss on one that has clearly broken.
Pop Quiz
Three quick questions to close out the course. Pick an answer and the explanation shows up right away.
Why is chasing the strike with the richest premium often a mistake?
A fat credit and a high chance of being tested come from the same place: proximity to the stock price. Selling for the number alone ignores the odds behind it.
Why should you usually avoid selling premium right before earnings?
The premium looks unusually rich because the market expects a big move. That richness is compensation for a real risk, not free money.
Why does a strangle need to be sized smaller than a defined-risk spread?
Without a wing, the loss on a strangle is undefined and grows with the move. Sizing it like a capped spread is how a single bad month does outsized damage.
Bottom Line
You have reached the end of this course, and the lesson it all points to is simple: you already know enough. Chasing rich premium, fearing assignment, selling through earnings, oversizing undefined risk, and rolling a broken trade forever are not knowledge gaps. They are discipline gaps, and every fix is something you now carry. Weigh the odds, respect the calendar, size undefined risk with care, and know when to take the loss, and you will be ahead of most sellers who know just as much and apply far less.
That's the full Income Trading course. If you want to go deeper on managing risk across your whole account, the Risk Management course picks up right where this leaves off. If you want to trade volatility itself rather than just sell it, Volatility Trading is the natural next stop. Trade well, stay disciplined, and enjoy the income.
