5 Emotional Trading Mistakes I Still Catch Myself Making

I noticed the mistake about twenty minutes into the position. The trade was working — up nearly half my target — and I was already reasoning about where to add. Not because the setup called for more size. Because I felt like I was right, and that feeling had quietly taken over my thinking.

That's one of five emotional trading mistakes I catch myself making on a regular basis. I've been trading long enough to name them on contact. The uncomfortable part is that naming them doesn't always stop them.

The 5 Emotional Trading Mistakes That Keep Showing Up

These aren't textbook patterns. They're things I've logged in my own journal dozens of times, and they still appear. The difference is I catch them faster now.

1. Anchoring to my entry price

Once I'm in a trade, my entry becomes emotionally significant — even though the market doesn't know or care where I got in. When price pulls back toward my entry, I start reasoning: "It just needs to hold here." When it approaches my stop, I start bargaining with myself.

This is anchoring bias — a well-documented cognitive distortion where the brain assigns excess meaning to an arbitrary reference point. In trading, that reference is almost always your entry price. It warps how you read what the market is actually doing.

2. Sizing up when I'm on a hot streak

Three good trades in a row and something shifts. I start treating recent results as evidence that my edge is working at a higher level — which might be true — and use that feeling as justification to take bigger size. The risk management logic quietly disappears.

Brett Steenbarger, who coaches professional traders, calls this "emotional portfolio management" — where position size reflects your emotional state rather than your analysis. His work on trading performance psychology has some of the clearest thinking on this pattern I've found.

3. Holding through my stop because "it'll come back"

I know this one cold. I've written it in my journal. I've lost real money to it. And I still do it.

Price hits my predefined stop level, and instead of closing, my brain generates a plausible story about why this situation is different. The news context. The time of day. Something about the spread. By the time I've reasoned my way to "the setup is still valid," I'm well past where I should have exited.

What's happening here is confirmation bias — the cognitive tendency to selectively seek and weight evidence that supports an existing position over evidence that challenges it. Understanding how this filter operates in a live trade is one of the more useful things you can do for your exit discipline.

4. Chasing moves I missed

The setup triggers while I wasn't focused. It runs 60% without me. I enter anyway — convinced it has more room — and buy into an exhausted move.

This is where FOMO in trading and emotional mistakes directly overlap. The discomfort of watching a move without you creates pressure to act, and that pressure overrides your entry criteria. It's the same neurological mechanism; just dressed differently each time.

5. Monitoring my P&L every two minutes

This one doesn't look like a mistake. It looks like staying informed.

But watching the account balance tick up and down — rather than the price structure I'm supposed to be analyzing — means I'm managing my emotional state, not the trade. Every minor drawdown triggers a micro-stress response. By the end of the session I'm mentally depleted, and depletion makes every remaining decision worse.

Why Do Emotional Trading Mistakes Keep Coming Back?

Here's the frustrating part: you can know your patterns exactly and still fall into them. The reason is that emotional trading mistakes rarely present the same way twice.

The anchoring mistake one session looks like refusing to exit a losing position. The next time, it shows up as over-confident position building at a price that "should hold" because it's near your entry. The emotional driver is identical; the presentation is different enough that your pattern recognition doesn't fire.

This is also why reading about emotional mistakes — including this post — has limited direct effect. Jared Tendler, who applies performance psychology to trading, makes this point clearly: insight without a behavioral anchor doesn't transfer into live trading. The insight has to become a specific, pre-committed procedure.

What Actually Helps

A few things that have genuinely moved the needle for me:

• Name the mistake out loud the moment you notice it. "That's the hot-streak sizing thing." The act of labeling interrupts the automatic process — it pulls you from reactive mode back into deliberate mode before you complete the action.
• One hard rule per mistake, not one principle. A principle is "I'll manage my emotions better." A rule is: "After three winners, my next position is 50% of normal size. No exceptions."
• Track the mistake, not just the outcome. A bad process that wins is still a bad process. What you write in your trading journal matters most when you're logging how you behaved, not just the result.
• Review your error patterns weekly, not only your P&L. The behavioral log tells you far more than the profit line.

Can You Eliminate Emotional Trading Mistakes Entirely?

In my experience: no. The goal isn't zero emotional mistakes — it's shorter mistakes, caught sooner, with less damage per occurrence.

After years of logging my behavioral patterns consistently, the mistakes still appear. But the anchoring mistake that used to run 200 points against me now gets caught at 40. The hot-streak sizing that used to hit 3× risk now gets noticed before I place the order.

That compression came from making the patterns visible. I built MindTradr because I needed a way to track both my trades and the emotional decisions behind them — not to shame myself, but to make the cost of each mistake undeniable. MindTradr is a trading journal that captures behavioral data alongside P&L, so patterns stop being something you can explain away and start being something you can actually fix.

When you can see that your "held through stop" trades have a 22% win rate versus 61% for your rule-following trades, the rationalization weakens considerably.
