The best investors avoid 'revenge trading' and other raw emotions. Here's how you can too.

By Michael Sincere

It's not stock charts; it's your mindset. This veteran trader's insider tips can sharpen your skills.

'Remove the emotional weight of money, and suddenly doing the right thing becomes easy.'

Deron Wagner, founder and CEO of Morpheus Trading Group, has adopted a psychology-first methodology to the stock market that prioritizes mastering emotions - fear, greed, hope and regret - before learning technical analysis.

For Wagner, being smarter about investing and shorter-term trading comes down to one overarching truth: "The market doesn't care what you think." And because of this, successful investors have learned to trust their gut - not their head.

Wagner discussed this and other investing rules in this recent interview, which has been edited for clarity.

MarketWatch: If you could fix one psychological issue in every trader, what would it be?

Wagner: Trade what you see, not what you think. That one sentence is incredibly powerful because it means react, don't predict. Trading what you think means looking at a chart and saying, "I think this is going up. I think it'll do this next month." That's predicting, and you'll be wrong most of the time.

The market doesn't care what you think. Instead, make a paradigm shift. Trade what you see right now: "What is the market doing at this moment?" Make your decision based on what you see, not what you hope happens tomorrow.

This applies to both entries and exits and eliminates all four destructive emotions: fear, greed, hope and regret. It forces you to focus on what the charts are actually telling you, not what is in your head. Rewire your thinking around that principle, and you'll transform your trading.

MarketWatch: What's the biggest psychological mistake you personally have made as a trader?

Wagner: My biggest recurring mistake was revenge trading - getting stopped out of a trade, then jumping back in hours later, convinced I'd just mistimed the entry, only to get stopped out again. I learned to ask myself one question before re-entering: "If I'd never been in this trade before and saw the chart right now, would I enter?" If yes, it's valid. If no, I'm revenge trading based on emotion. I discovered this pattern by keeping a detailed trade log: recording not just wins and losses, but what I was thinking at each entry and exit. Reviewing it weekly, I saw clearly: My biggest losing streaks always came from revenge trading. That awareness forced me to develop discipline.

'The most dangerous emotion is hope.'

MarketWatch: What emotion does the most damage to traders?

Wagner: The most dangerous emotion is hope. Four main emotions drive every market - fear, greed, hope and regret - but hope is the deadliest, because it creeps in when a trade hits your stop loss and you don't honor it. You think, "Maybe it'll bounce. There's support here. Good news is coming."

Three days later, it's down another 5%, and what should have been a small loss has compounded. The stock doesn't care what you hope. You're basing decisions on luck and ego, not reality.

Fear shows up differently: When you didn't honor your stop, hope transforms into fear. Now you're down 10%, feeling gun-shy and psychologically paralyzed, unable to pull the trigger on new opportunities.

This is why mastering emotions is everything. When I started trading 25 years ago, everyone taught technical analysis first and treated psychology as an afterthought. That's backwards. Now, before I show students a single chart, we focus on mastering emotions. Get that right, and the rest falls into place.

MarketWatch: Why do even experienced traders break their own rules?

Wagner: The biggest reason is they don't have their rules written down in a trading plan. If it's just in your head, it's too easy to rationalize exceptions. Trading is a business, and you wouldn't start a business without a business plan. Whether you're trading your first day or your 20th year, you need a written trading plan to prevent repeating the same mistakes.

Another tool that helps is an accountability partner - another trader who struggles with similar challenges such as discipline or patience. At the end of each day, you text each other: "Did I follow my rules today?" You keep each other honest. Once following your rules becomes a habit, it's easy, but you have to break the bad habits first.

MarketWatch: What's the most common way greed destroys traders?

Wagner: Greed shows up as "FOMO" - "fear of missing out." People watch a stock rally for months, not believing it's real, then they can't take it anymore and jump in, saying, "I gotta buy this." That's almost always near the top. If you miss the proper entry point, move on. There are thousands of opportunities every day. Don't chase something already up 400% in three months. Greed also causes overleveraging: You keep adding to a winning position without moving your stop up to protect profits, then suddenly bad news hits, and what was your biggest winner yesterday wipes you out today. Keep greed in check by defining how much you're risking per trade and sticking to those rules.

'You're not smarter than the market.'

MarketWatch: How can retail traders counter institutional manipulation?

Wagner: The key is understanding their tricks. I used to be a proprietary trader and hedge-fund manager, so I know how institutions think. One major trick: They know exactly where retail traders place stops - at round numbers such as $90.00 and at obvious support levels like moving averages. You'll see prices dip to $89.93, just enough to trigger stops, then reverse immediately. Institutions hunt those stops deliberately. The solution is "wiggle room." Instead of setting your stop at the obvious level, add half-a-percent cushion. If $198 is support, set your stop at $196.80. In crypto, you might need a full 1% buffer.

The other critical tactic is being prepared to re-enter, but this isn't revenge trading. I'll often test a position with small size, knowing I might get stopped out two or three times before my timing is right. Each stop is tiny, so one winning trade wipes out those small losses. Institutions will shake you out of good positions, but if you have a rule-based strategy and you're willing to re-enter when the setup is valid, you can turn their manipulation to your advantage.

MarketWatch: Can traders actually fix their psychological issues, or do most just wash out?

Wagner: It depends entirely on self-awareness. Some traders have massive egos and think they know better than the market. Those traders get beaten repeatedly until they change that thinking or wash out.

The first step is acceptance: You're not smarter than the market. That's hard to admit, but you can't change until you accept you have an issue to fix. Once you have that acceptance and genuine desire to improve, psychology can absolutely be mastered. One trader I worked with had traded futures for seven years with inconsistent results, breaking even most years. After focusing on mastering his psychology first, he's up over 400% in his account. When I asked what made the difference, he said, "100% trading psychology." I've seen similar transformations. Even a lawyer who constantly fought the market and wouldn't cut losses finally learned to master his emotions.

'Did you follow your rules? That's the only question that matters.'

MarketWatch: What do you tell traders who know exactly what to do, but keep sabotaging themselves?

Wagner: Three things. First, get an accountability partner - ideally another trader who understands the pressure, but even a spouse works. My wife isn't a trader, but when I tell her my results, she doesn't ask if I won or lost. She asks, "Did you follow your rules?" That's the only question that matters because if you follow your rules, you'll be fine long term.

Second, use the "5-5-5" breathing method: When you're stressed in the middle of a trade, close your eyes and take five deep breaths, five times, holding each for five seconds. It clears your head instantly and makes it much easier to follow your rules. This isn't about meditating for an hour. It's about creating pauses that bring self-awareness.

Third, reduce your position size dramatically. If you normally trade $10,000 positions, drop to $100 while you break bad habits. The goal isn't making money; it's making the money irrelevant so you can focus purely on, "Did I do the right thing?" Track your next 20 trades at tiny size with zero financial pressure. Once you prove you can follow your process, gradually increase your size. Remove the emotional weight of money, and suddenly doing the right thing becomes easy.
