Nice to meet you. I am 投資郎, the chief researcher at FX Logic Institute. At our institute, our philosophy is to understand the market not by sense, but by "logic," and we conduct research and development of reproducible trading methods and systems. The market changes daily, but there are universal aspects to human psychology and the essence of the market. We verity that essence, and by performing numerous chart analyses, backtests, and forward tests, we aim to shape "logic that can be used for a long time." Beyond FX, domestically and internationally, we operate multiple businesses including: IT/Web system development Web marketing Application development Real estate investment Travel and tour services We move our base of operations rather than staying fixed, traveling between Japan and many countries around the world as we work. What is common across various industries is: "reproducing results with data and mechanisms rather than intuition." This mindset applies directly to FX as well. To date, we have provided indicators and expert advisors (EAs) to over 1,000 traders, and have offered numerous individual support and consulting services. Of course, tools alone cannot guarantee profits. However, "why that logic?" "which market conditions offer an edge?" "in what situations should it not be used?" We place importance on communicating these honestly. What FX Logic Institute aims for is not tools for short-term gains, but logic that you can engage with for a long time. Rather than flashy ads or exaggerated expressions, we strive to create products that you can be convinced of the more you use them. Thank you very much in advance.

Series

What I learned from studying USD/JPY for 22 years

A series of articles that only the FX Logic Institute can write, aimed at breaking the beliefs that many traders hold in FX.

[Episode 10] Is "Daily Trading" Really Necessary?

When I first started FX, I believed that “trading every day” was the shortcut to improvement.
To gain experience, you have to trade by cutting through the numbers.

You must not miss opportunities.

A day without trading was a day you could learn nothing.

That’s what I thought.

However, after testing 22 years of USD/JPY data and building a trading logic, that thinking changed dramatically.

I have never regretted a day I did not trade.

“Doing nothing” is not a passive choice.

In FX, entering a trade is considered action, and refraining from trading is often viewed as doing nothing.

However, from the perspective of validation (testing), it’s a bit different.

You review the chart according to the rules, and

you skip because the conditions are not met.

That is also a legitimate judgment.

Rather, in terms of adhering to the rules, abstaining is as important an action as entering.
