There’s a word for this – pareidolia. It’s our brain’s tendency to find familiar shapes in random things. Thanks to it, we see animals in clouds, a smiley face on a fried egg, or a head‑and‑shoulders pattern on an oil chart late on a Friday evening.
This isn’t mindlessness or lack of attention. It’s the perfectly normal work of a brain shaped by millions of years of evolution for one task: to detect patterns everywhere and as quickly as possible. Our ancestor who saw a tiger in the shadows and ran – survived. The one who didn’t – didn’t.
The problem is that in financial markets, this mechanism works against us. The brain doesn’t just passively look at a chart. It actively searches for what it expects to find. If you want to buy, you’ll see bullish signals. If you’ve already decided to sell, you’ll see bearish ones. This is called confirmation bias, and no one on the planet is immune to it – not even hedge‑fund managers with twenty years of experience.
In practice, this can be explained with one simple experiment.
Take any sideways section of a chart, for example, EUR/USD for two random months in 2025. Show it to two groups of traders.
- Tell the first group: “Find a head‑and‑shoulders pattern.”
- Tell the second group: “Find a double bottom.”
Both groups will find exactly what you asked them to find. On the very same chart. This means that chart interpretation begins earlier than you think – at the very moment when the search request is formed.
When the Risk Is Especially High
Phantom patterns don’t appear randomly. There are specific situations in which the brain becomes particularly active in “drawing” things that aren’t there.
- After a series of losses
You’ve been in the red for three days in a row. The brain wants to recover the losses and starts seeing “sure things” in every second candle. At this moment, phantom patterns are the most convincing – and the most dangerous.
- In a sideways market
When there’s no trend, no structure, and the price is just drifting, the brain gets bored. It starts building structure out of chaos. Flags, triangles, wedges – all of these are easy to “find” in a range‑bound market if you really want to.
- After someone else’s analysis
This one is especially tricky. You see someone’s chart markup, neat arrows, a confident commentary. Now you look at the same chart – and you simply cannot unsee what they showed you. This is called priming, and it works even when you’re fully aware of it.
Why Do We “See” What Isn’t There?
- The desire to be right
When you enter a long position, your brain starts filtering information. It ignores red candles and “draws” a bullish flag out of any pullback. We don’t see what is actually on the chart – we see what confirms our position.
- Fatigue and a “blurred” eye
After four hours of staring at the screen, price action turns into a kaleidoscope. In this state, the brain switches to autopilot and begins inserting textbook technical patterns anywhere the curve bends even slightly.
- Fear of missing out (FOMO)
When the market is moving aggressively, and you’re not in a trade yet, the brain starts desperately searching for a reason to jump in. And of course, it finds one: “Look, that’s clearly the third Elliott wave!” Even though in reality it may be nothing more than ordinary market noise.
Practical Tips: How Not to Fall Victim to Pareidolia
- Use checklists, not intuition
Instead of trusting your eyes, trust your conditions. Write down 3-4 clear criteria for your pattern. If even one of them is missing – the trade is canceled. This turns the process from “drawing in your head” into a mechanical verification.
- Switch time frames
If it seems like a reversal is forming on the 5‑minute chart, switch to a higher time frame, for example, M15 or 1H. Very often, a “pattern” on a small timeframe turns out to be just a single insignificant candle on a larger one. This is a great reality check.
- Let the chart “settle”
If you think you see a pattern, step away from the computer for five minutes and drink some water. When you return, look at the screen with fresh eyes. If the formation still looks logical rather than forced, you can work with it.
- Accept the chaos
The hardest and most important thing is to acknowledge that most of the time, the market has no patterns at all. There is simply price movement. The ability to sit on your hands and wait for that truly “obvious” moment – that’s what professionalism looks like.
- A markup‑free screenshot
Before every entry, take a screenshot of a clean chart – no lines, no arrows, no annotations. After the trade is closed, go back and check: was the pattern visible without your “help”? After a month of keeping such a journal, you’ll learn more about your own pareidolia than in years of trading.
- The neighboring‑instrument rule
If you see a pattern on XAU/USD – open a correlated instrument, such as XAG/USD. A strong structure should be mirrored and confirmed on the correlated asset. If there’s nothing there, your pattern is questionable.
- Describe your entries out loud
If you can’t verbally explain the logic behind your entry, then you haven’t actually seen a pattern – you’ve invented one. Describing the situation out loud helps filter out the excess mental noise that constantly spins in a trader’s head, especially for intraday traders prone to overthinking.
Final Thoughts
The brain is an amazing instrument. But it wasn’t built for trading. It was built for survival, and pattern‑seeking in chaos is one of its core functions. That’s why trading is not a battle with the market – it’s a battle with your own illusions.
The good news: now you’re aware of this. Which means you can compensate for it. You don’t need to fight your brain – that’s pointless. You just need to add a few checkpoints to your process, ones that activate analytical thinking in places where instinct used to run the show.
