The Most Common Mistakes That Cause Traders to Fail a Challenge
Failing a challenge is a typical situation that almost every consistently profitable trader has experienced, especially at the beginning of their trading journey. The vast majority agree that the main reason for their early failures was not a lack of intelligence, an overly simple strategy, or the idea that prop trading itself is a scam.
In reality, these mistakes most often stem from a lack of discipline, the absence of risk management, overly ambitious expectations, or a failure to understand the criteria required to pass a challenge.
Trading is not about luck, but about discipline
Oversized Positions and the Need to Hit the Target Fast
Among the most common mistakes is opening overly risky positions in an attempt to reach the profit target as quickly as possible.
Although there are exceptions, a position can generally be considered risky when 2–5% of the total account size is allocated to it. Excessive position size is often linked to overconfidence, gradually increasing trades to dangerous levels, or simply trading too frequently.
These mistakes can quickly lead to failure in a challenge — either by exceeding the daily drawdown, or through several losing trades in a row that result in reaching the maximum drawdown on the account.
Position size matters more than the speed of profit
The Absence of Risk Management as a Direct Path to Failure
The complete absence of risk management can be just as damaging. A large number of beginner traders set take profits and stop losses almost randomly, exposing their account to extremely high risk. This approach resembles gambling far more than trading with clearly defined rules.
Revenge Trading: The Urge to Win Losses Back Fast
Another very common phenomenon is revenge trading, behavior triggered by previous losses. As the name suggests, it is the attempt to “get back” at the market and recover losses as quickly as possible.
Revenge trading can take several forms. The most common include:
- Increasing position size to recover a previous loss
- Opening as many trades as possible
- Taking low-quality setups with a lower probability of success
From a risk management perspective, this exposes the entire account to extreme risk. Low-quality positions are also often associated with entries made without clear confirmation from relevant indicators.
Without risk management, emotions take over
Fear, Greed, FOMO, and Impatience
Impulsive behavior is closely linked to the emotions traders experience while trading. The most dangerous among them are fear, greed, FOMO, and impatience.
Unlike revenge trading, these emotions often appear as a reaction to economic or political events. Out of fear, traders often open short positions that are rarely based on objective analysis and data.
On the opposite side of the emotional spectrum stands greed. This is particularly risky during periods of general market euphoria and rising prices. Excessive optimism creates the false impression that the price of a traded instrument will continue rising.
Just like fear-based trades, these overly optimistic entries are usually not grounded in concrete analytical data.
FOMO: The Fear of Missing Out
In prop trading, a very common combination of the two emotions above is FOMO, or Fear of Missing Out.
This describes a situation where a trader feels they have missed a specific trend — most often a rising trend in a financial asset — and if they do not enter immediately at any cost, they will miss the opportunity for profit.
In addition to the mistakes FOMO naturally causes, the main issue lies in opening an overly large long position at too high a price — often near the very top. Shortly afterward, a market drop may follow, causing the entire challenge to fail.
A Challenge Is Usually Not Lost Because of the Market, but Because of the Trader’s Mistakes
Many traders believe that the market itself is what determines the outcome. In reality, a challenge often does not fail because of the market alone, but because of the mistakes a trader makes under pressure.
That is why it is essential to understand that success in prop trading is not built only on strategy, but also on discipline, emotional control, and consistent risk management. Without these pillars, even a solid trading plan can fall apart very quickly.
