12 Reasons Why Day Traders Fail (Avoiding The Common Pitfalls Of Day Trading)

Why day traders fail boils down to at least 12 reasons. This article explains why day traders fail and what you can do to survive and perhaps even prosper.

Why day traders fail is mostly because they don’t understand the ecology of the markets, have no game plan, trade too big, and don’t know their risk tolerance. 

Day trading certainly holds promises of a fast-paced working environment with high returns. Its allure proves practically irresistible to many new traders. It is also a common belief that most day traders don’t make much money, and many more are even confronted with the possibility of losing their trading deposits in a single year. This begs the question:

How many day traders are losing money?

What percentage of day traders fail? Just a few day traders make profits, as most traders become the prey, instead of the predator. How many of them out there are losing money? There isn’t an exact answer, though likely no less than 90% will have fallen under that category, whereas only 1% are likely to be out there “making a killing”. Sadly, this also happens to make a lot of sense.

Why? Many day traders fail because they don’t understand how the markets work:

Reason 1: Day traders don’t understand the ecology of the markets

Due to its competitive nature, day trading could more or less be seen as a zero-sum game. The same thing happens in poker – not everyone is going to end up a winner. 

You must understand the market and its players first. Who are your rivals? Who are the predators?

Compare day trading to long-term investing. Since the end of the second world war, the US Stock market has gone up 6-7% annually in real terms. And why is that? That’s because it is not a zero-sum game in the long term.

Companies earn money through increased profits and the US Treasury keeps on increasing the money supply. It’s hard NOT to make a decent return as long as you have a diversified portfolio. By simply being patient and building a stock portfolio, you’re increasing your chances of making a profit.

Alas, this isn’t very exciting, and it won’t happen overnight. Most new traders can’t wait to make that first buck.

Reason 2: Few day traders use quantified strategies and thus fail

The main reason why most day traders fail is that they start day trading without a trading edge. A trading edge is more important than psychology and risk management. They’ll need an edge to succeed. Having a trading edge means that your trading setup has a higher possibility of being successful, which can be translated into a greater than 50% chance win rate, or you make more from the winners than the losing trades.

Quantifying in day trading becomes even more important once we consider the sheer amount of noise and randomness.

Having a strategy for day trading often feels like a daunting task. Trading always takes uncertainty into account. All trading decisions have a financial impact. Therefore you need to find your own trading strategy. Your best option is to use a step-by-step approach to learning how to build a trading strategy that’s completely separate from discretionary trading.

Reason 3: A day trader needs a trading plan to avoid failing

Regardless of your trading style, having a trading plan will prove to be the key to your success because day trading requires both foresight and strategy. Once you look at day trading as a day job, you’ll realize the importance of having a trading plan in advance and avoiding the common issues experienced by new traders: not having a real game plan for what and where to buy.

And please make sure you have a trading journal – we have provided you with a trading journal example.

Your trading plan should cover every aspect of the trading process. You must know which market you want to trade, which strategy you want to use, and what kind of trade management technique to use. It would help if you also considered which time frames to use, be it 15 or 30 minutes to an hour, perhaps testing strategies outside the regular trading hours. You should also have determined a proper position and have clearly defined risk parameters.

Reason 4: Follow your passion -not money

Day trading is often defined by its scalability – its ability to make money fast. That is what attracts beginners, which honestly makes little sense. Without passion, you’re bound to lose. You must first love what you do and then detach yourself from the outcome.

Reason 5: Day traders fail because they trade too big

Another way to increase your losses is to trade position sizes that are too big for your account.

New traders usually do this as they attempt to increase their potential profits since the regular price movements in the intraday timeframe are seemingly too small to offer them any reasonable profit.

They’re missing the point. A single trade won’t be enough to increase their profits. Success always requires consistency which you achieve by building up some small, but frequent, profits over time.Day traders fail because they don’t understand their risk tolerance

Reason 6: Day traders fail because they don’t understand their risk tolerance

It’s important to understand your risk tolerance level. Day traders fail because they take too much risk – they are in a hurry to get rich. When they get a drawdown, they quit or abandon the strategy.

This is a lesson that beginners tend to learn through sheer experience. Why is that? One of the most important things in trading is to detach from money. That is difficult if you don’t understand your risk tolerance.

Trading too big, and you will most likely not follow the plan. How significant drawdowns can you suffer before you lose faith and give up?

Reason 7: Day traders fail because they are not patient

New traders rarely take their time to learn. They start trading believing that profits are made instantly in their pursuit to get rich quickly.

They want to start trading before even understanding the difference between a pullback and a trend. They barely have a grasp on market changes. It’s not uncommon to see new traders rush to bet their money in the market without knowing anything about the trading process. They still believe trading is an easily acquired skill. They’re not traders, they’re gamblers.

Trading requires more than just hard work, it also requires time, study, and numerous failed attempts before it ever becomes successful. Even after learning the basics, experienced traders still dedicate themselves to developing new strategies.

Reason 8: Day traders fail because they do it for the thrill – and thrillseekers fail

Some day trade for the excitement, we believe the best stocks are the most boring stocks. While achieving success can be exhilarating, you can’t make money without preserving your capital. As Warren Buffet puts it, protecting your trading capital is the number one rule.

Not knowing when to close a losing trade can amplify a loss dramatically – a small loss grows into a big one. Losses make it harder to make a comeback. If you lose 50% of your capital, you need 100% to get back to even.

Reason 9: Day traders need to adapt constantly or end up failing

New day traders have a hard time adapting their strategies to an ever-changing market. They rather stick with whatever strategy that works for them, believing it will continue to do so indefinitely.But it won’t. All strategies at one point stop working.

But no single trading strategy lasts forever. Some are designed for a range-bound market and others for a trending market. As soon as market conditions change, a trader should be smart enough to choose a more favorable strategy. New traders would be wise to have more than a few uncorrelated techniques and strategies up their sleeves. You need to understand correlation in trading and how to mix strategies with different time frame, different markets, and different directions.

Reason 10: Lacking the mindset means you fail at day trading

Day trading is more than just creating strategies and developing criteria, it’s also about controlling your emotions and how they affect your trading. Hope, anger, despair can affect how your trades.

Moreover, we carry many trading biases with us. Loss aversion, anchoring, confirmation bias, “resulting”, etc. are just a few of them. We recommend reading Annie Duke’s Thinking In Bets to get a better understanding of how to make proper decisions.

Reason 11: Day traders fail because they make trading complicated

It was Robert Pretcher who once said that most traders often increase the risk of ruin by trying to make the system into a perfect one. The future is rarely the same as the past, thus the pitfalls of curve-fitting are always present, no matter how tempting it is to fiddle with the strategies to make them perfect. A simple system, with few variables, is likely to last longer than one with many variables.

Reason 12: Day traders force trades – why day trade?

Many traders start by having a goal of making, for example, five trades per day. This is, of course, the wrong approach. You can’t force trades, you need to take what the market offers. If you can only find strategies that trade on average two times per day, then so be it.

We suggest you widen your horizon and include trades that might last over many days – swing trading. A trader needs to be agnostic and open to all opportunities that the market offers. 

Make sure you survive

Many only move to day trading when they’re looking to make a quick buck. But trading is about protecting your capital so you can live another day to trade. If you’re spreading a quarter of your investments with each new trade, then you’re not going to survive for very long. A few losses will be enough to take you down. This is something you need to keep in the back of your head at all times.

Why day traders fail – conclusions

Make sure you are the predator and not the prey and use the ecology of the markets to your advantage. Accept that losing trades are part of the game, thus you need to control your losses.

Make sure you have a plan and only trade strategies that are backtested and quantified, and that you are diversified in terms of trading many uncorrelated strategies. Use the law of big numbers to your advantage and detach yourself from money and the financial outcome.

But finally, let’s be honest: Why day traders fail is because they have absolutely no clue what they are doing. Most fail at the starting line because they have no clear plan, they simply don’t know how to make money, and they don’t understand the markets.


– How can understanding market ecology improve day trading success?

Understanding the competitive nature of day trading and recognizing it as a zero-sum game is crucial. Knowing who the market players are and identifying rivals and predators is essential for success.

– Why is having a trading edge important for day traders?

A trading edge is crucial for day traders as it increases the probability of success. Without a quantified strategy with a higher-than-50% win rate, day traders may struggle to make consistent profits.

– What is the significance of a trading plan in day trading?

Having a trading plan is key to day trading success. It covers aspects like market choice, strategy selection, trade management, time frames, position sizing, and risk parameters, providing a roadmap for effective trading.
