Nice to meet you. This is Mr. Ojun from BuilderOU (Builder King). I am active in binary options (BO) and FX under the principle of "Honest verification creates a reproducible future." When I first started investing, like many others, I approached the market with the feeling, "I want to earn quickly." However, the results were far from smooth. Being swayed by information, trusting products, losing funds, and trading driven by emotions. I experienced many detours. In the end, the answer I arrived at was, "Make judgments by verification, not by intuition." A very simple mindset. Nowadays, - Developing tools through programming - Long-term backtesting - Real-trade verification - Research into money management - Accumulation and analysis of verification data We pursue creating a trading environment with reproducibility on a daily basis. Thus far, through word of mouth, I have shared about investing with approximately 300 people. And this time, for the first time, I decided to start disseminating information on the internet. There is only one reason. Around me, there are many people who, like my past self, believed in online information, products, and influencers' words, and lost valuable funds. That is why I want to spread a culture of verification, not the goal of selling. In this Investment Navigator, - Verification results - Behind-the-scenes of development - Logic that was adopted or rejected - Feelings from real trades - The process of product development will be communicated, including not only good results but also failures. If my articles can become a trigger to protect your precious funds, there is nothing more to wish for. Thank you very much for your support.

Series
Honest verification creates a reproducible future (BuilderOU Story)
I, who kept losing, was able to change my life through "verification" The reason I started investing was not to grow my money. I wanted to repay my parents' debt. That single-minded motive is why I started investing. But reality was not sweet. I tried methods said to be "winning", bought indicators, joined schools, and if I lost, I looked for a new method. It was a repeating cycle. What I realized then was: The ability to verify is many times more important than a method that can win. In this series, I will write without hiding based on my real experiences about: - the reason I started investing - repeated failures - encounters with backtesting - why I began to create indicators - creating reproducible rules - verification methods - the behind-the-scenes of product development - actual verification results It may not be suitable for those looking for an "easy way to win." However, If you are serious about winning consistently for a long time, I aim to provide at least one takeaway you can apply. Please stay with me until the end.

BuilderOU STORY【Chapter 1】Episode 13 — BuilderOU, who was only a name, begins to move

BuilderOU STORY｜Episode 13

BuilderOU, which had only been a name,
begins to move

Teach. Verify. Create. Support.
From separate experiences, into one business.

Hello.
BuilderOU (King Builder)
This is Mr. Ojun.

In Episode 12, I spoke about how some people I taught began to generate profits, while others broke the rules after winning, raised their living standards too much, did not think about taxes, or lost their funds.

I thought that if I taught a trading method, the other person could practice it in the same way. If I conveyed knowledge, they could approach the same results.

However, what was taught and what actually happened were different.

Understanding. Practice. Persistence. Continually following the rules. Each of these is a completely different problem.

Simply imparting knowledge does not create reproducibility.

A教材 that is easy to use for anyone. A verification environment where results can be confirmed. A system that protects funds. A standard to revert to when mistakes are made. And a format that can continue to support after teaching.

If you don't create that much, you can't really support people's futures.

From here, I began to think about creating a business that not only teaches with goodwill but also delivers responsibly.

What had been only a name, BuilderOU, began to move in a real sense.

1. The past things had
all been separate


I have created many things so far.

Indicators. Programs for backtesting. Excel sheets to analyze results. Rules for money management. Notes to explain to people. Records of questions from each person.

Conditions that failed. Times when I couldn't win. Sign tools that couldn't be used.

When looked at one by one, each was different.

However, simply existing separately, the user would have to understand all of them on their own.

Using indicators. Taking backtests. Transferring results to Excel. Segmenting by time. Checking win rate. Setting money management. Recording trades. Considering reasons for failures.

It's not easy for a beginner to do all of that alone.

I spent years learning through failures.

However, later entrants do not have to take the same long detour.

Could I connect what I have made so far into one flow? I began to think this.

2. The order of teaching,
which had to be created


Until now I answered questions from others.

If they didn't understand how to read a chart, I explained the chart. If they were struggling with money management, I explained money management. If losses continued, I looked at trading history to consider causes.

I conveyed what that person needed each time.

However, people learned in completely different orders.

Some people try to learn only winning methods without understanding the basics. Some try to memorize entry methods without deciding money management. Some begin real trading without taking backtests.

Even if you teach the same content, the reception changes depending on the foundation.

When building a house, you can't start with the roof. Build the foundation. Erect the columns. Build the walls. Then the roof. There is a order.

Trading is the same.

What to learn first. What you must be able to do to move on. Where to verify. Where to practice. If you fail, how far back you return.

There was a need to create that flow.

The important thing is
not to dump a lot of knowledge at once.

Create a sequence that you can advance without hesitation,

and provide places you can return to if you make a mistake.

3. Verification,
which I wanted to make accessible to anyone


I have emphasized the importance of backtesting many times.

However, simply telling people, "Please verify for yourself," many people still couldn't take action.

What should be verified? Over how many years should one investigate? How should signals be counted? How should wins and losses be judged? How should time frames be divided? How should it be entered into Excel?

At that point, there are too many unknowns.
