After testing thousands of variations, we found the mechanism by which "10% per month" blows up your account

In a demo trade, there was a time when capital increased by 15% in one month. At that moment, honestly, I thought, "This might work.""If I can keep 10% per month, the capital will be more than tripled in a year."— I was tapping my calculator, smirking. And with that momentum, I brought the same method into a real (live) account,and was wiped out in two weeks.

This article analyzes that failure. The theme is"Why aiming for unrealistic goals brings you closer to getting wiped out". To put it simply, the problem isn’t mental state or luck, butthat excessively high goals themselves force a design that takes excessive risks.

Forgive me for the introduction,lulu.fx. I am a current discretionary trader focusing on GOLD (XAUUSD), who builds and tests EA programs myself, and I continue to run verifications. I am currently challenging a prop firm (Company A).

This "Verification reveals: Why FX beginners can’t win" series documents, by comparing a vast amount of data and demo trades, thetrue reasons beginners can’t win, one by one. This time is the second installment. It tackles the root cause of "winning in demo but losing in real" —"mistakes in goal setting".

The confidence you gain from winning in demo is the most dangerous

First, the initial pitfall.When you win big in demo trading, people overestimate their own ability. I was the same. When I saw +15% in a month in a demo, I believed it was because my method was excellent. But, in reality, that wasn’t the case.

As I wrote in the previous article, in a demo the spread is narrow, executions are perfect, and most importantly,there is no weight of money. Losing doesn’t sting at all, so I can boldly take larger lot sizes. I can cut losses without hesitation. In this "pain-free environment," I mistake the excellent results for my real ability. This is the entrance to ruin.

The problem is, that mistaken confidence thenmorphs into an "unrealistic goal" in the next step. If you think, "since I made +15% in demo, I can surely make +10% in real," this line will choke you later. Because chasing a figure like +10% per month willdistort the design of your trades in a dangerous direction. Let me explain in order.

High goals force you to take excessive risks

This is the point I want to emphasize most in this article.When the goal is high, you feel compelled to take risks to achieve it. This isn’t a matter of willpower or personality; it is a math problem.

For example, suppose a method has a fixed average edge per trade. To achieve +10% in a month with the same method, you must eitherincrease the lot size by more than three times compared to when aiming for +3% in a month, or unnecessarily increase the number of trades. Increasing lot sizes increases profits when you win, butthe drawdown when you lose also becomes proportionally larger.

In other words, aiming for +10% per month automatically entails accepting a design that tolerates temporary drawdowns of 10%, 20% and so on, and in markets, no matter how good a method is, there will be a period of drawdowns. Even the most advantageous methods can experience 5 or 6 consecutive losses. If you are risking large lots during those periods, your drawdown will balloon.A design aiming for +10% per month carries a bomb from the moment a streak of losses arrives, that can blow up your account.

What happened to me being wiped out in two weeks was exactly this. I took bigger lots in a demo-like mood, then came three consecutive losses. I tried to recover by increasing lot size further. Another loss occurred. By the time I realized it, I had exceeded the loss limit of the prop firm. It wasn’t that the method was bad.The goal of "monthly +10%" designed me to get wiped out from the start.

That concludes the free portion of this article. From here on, I will write about,"What is a realistic target?"—based on the numbers encountered in verification. I have tested countless logics and bounced off the same walls repeatedly—the structural ceiling. This is the discussion.
