Options Trading Lessons: The Mistakes That Cost New Traders the Most

Options Playbook Team

In nearly three decades in the options industry, I've watched traders of every skill level make the same mistakes. Not similar ones. The exact same ones. The options trading lessons that would have saved them the most pain aren't about finding better setups or predicting markets more accurately. They're about process, and most of them are entirely avoidable.

The lesson that costs traders money every day: no exit plan

This one comes first because it's the most universal. You do the analysis, you like the setup, you enter the trade. And then you have absolutely no idea what you'll do next.

The fix isn't complicated. Before you place any trade, decide two things: where are you getting out if it goes your way, and where are you getting out if it doesn't? Write them down. Then stick to them.

This matters more with options than with stocks because of time. Options are decaying assets. Every day that passes, a portion of your option's time value evaporates, and that erosion accelerates as expiration approaches. If you're long a call or put and the move you expected doesn't happen within the time frame you need, you don't get to wait around. You need to get out and move on to the next trade.

The traders I've seen blow up accounts weren't always wrong on direction. They were wrong on timing, and they had no plan for what to do about it.

Doubling down: the options trading lesson nobody wants to hear

A trade goes against you, and instead of closing it, you start thinking: if I liked this at $2.00, I love it at $1.00. So you buy more, lower your cost basis, and hope the market comes around.

That logic can sometimes work with stocks. It almost never works with options.

Options are derivatives. Their prices don't behave like stocks. As expiration approaches, a losing position doesn't just sit there waiting to recover. It continues to decay. When you double down, you're adding risk to a position with a shrinking window to turn around.

Ask yourself before you add to any losing trade: if I didn't already have this position, would I put it on today? If the answer is no, that's your answer. Close it, take the loss, and find a setup that actually makes sense right now.

Buying out-of-the-money calls as a first strategy

One of the most common options trading lessons new traders learn the hard way is that cheap options are seductive. You find a call that costs $0.50 per contract and think: how much could I possibly lose? A lot, as it turns out. Just not all at once.

Out-of-the-money calls are one of the hardest ways to make consistent money in this market. Three things have to go right: the stock has to move in the right direction by enough within the option's time frame. Even if you're correct on direction, time decay can still eat your position before the move materializes.

For traders new to options, the covered call is a better first strategy. You're selling time value rather than buying it, which puts theta on your side rather than working against you. It's not glamorous, but it teaches you how options actually behave far more effectively than chasing cheap OTM calls. You can read about how the covered call works and when to use it before placing your first trade.

Trading illiquid options

Here's a cost that doesn't show up in your P&L as a line item, but it's real. When you trade an option with a wide bid-ask spread, you're paying a hidden premium before the trade even starts.

Say you're buying an option with a bid of $1.80 and an ask of $2.00. Pay the ask, and you're starting the trade 10% in the hole. That's not a commission. That's the spread, and illiquid options will bleed you this way on every single trade.

A practical rule for filtering by liquidity:

  • Look for options with open interest of at least 50 times the number of contracts you plan to trade
  • If you're trading 5 contracts, the minimum acceptable open interest is 250
  • At-the-money and near-term options are generally the most liquid on any given stock
  • Avoid options on stocks trading fewer than 1,000,000 shares per day

Stick to liquid markets, and the spreads take care of themselves.

Waiting too long to buy back short options

When you sell an option, and it moves in your favor, there's a temptation to hold until expiration and collect every last cent. That's one of the more expensive options trading lessons to learn, and most traders learn it by losing money first.

My personal rule: if I can buy back a short option for 20% or less of what I collected, I close the position. I've already captured 80% of the maximum profit. That remaining 20% isn't worth staying exposed to an earnings release, a news event, or a sudden volatility spike that could reverse the entire trade.

A trade that goes from a $1.00 credit to a $0.20 option is a win. It stops being one if you sit on it too long.

Legging into spreads

This options trading lesson catches experienced traders and beginners alike. A spread is two options working together as a single trade. When you try to enter them one at a time, buying the first leg and waiting for a better price on the second, you're not trading a spread. You're holding a naked position while hoping to close it out.

This trap catches experienced traders, too. You buy the first leg, the market moves against you before you can put on the second, and now you're in a position you never intended to hold.

Enter spreads as a single order. Most brokers support multi-leg orders executed simultaneously. The fill price may not be exactly where you wanted, but it's a better outcome than finding yourself halfway into a trade with no hedge.

Ignoring early assignment risk

If you're selling options on dividend-paying stocks, early exercise and assignment are not theoretical risks. It happens, and when it hits traders who've never thought about it, they tend to panic.

When you're short an option, the buyer controls when it gets exercised. An early assignment can land in your account at any time, regardless of your plan. The main triggers to watch:

  • Call sellers face elevated assignment risk in the days before an ex-dividend date, when call owners may exercise to capture the dividend
  • Put sellers face assignment risk when positions move deep in the money as expiration approaches
  • Any short option can technically be assigned at any time, for any reason

The solution isn't to avoid selling options. It's to factor in the assignment before you put the trade on. Know what you'll do if it happens, and it becomes a routine part of the job instead of a crisis.

What connects all of these options trading lessons

None of these requires you to be a better analyst or a sharper forecaster. They're about having a plan, respecting how options actually work, and making the important decisions before you're in the middle of a trade rather than during it.
