EA Developer's Reiwa Double-E is Here.

Previously, I wrote about the idea of a “portfolio” that I value in developing and operating EAs.

This time, I’ll go a bit further,

“Why did I arrive at this idea?”

I’d like to write about this.

First of all, I want to say that this is not saying, “This trading method is the correct one” or “Please trade like this, everyone.”

It is,

my own experience and design philosophy—how I built my portfolio after developing EAs myself, operating them with my own money, and going through trial and error.

That is the story of my personal experience and design thinking.

My origin is discretionary trading

I was originally a discretionary trader.

While looking at charts,

“In this kind of price movement, there are these characteristics.”

“For this pattern, isn’t there an advantage in this area?”

I searched for these things and built them into my trading method.

And after starting EA development, I quantified that thinking and turned it into logic.

In my case,

EA isn’t the starting point.

Look at the market.

Search for features.

Form hypotheses.

Think about trading methods.

Quantify them as logic.

Test with backtests, etc.

Operate as an EA in practice.

This is the cycle.

Taking all market conditions with a single method is difficult

As I continued discretionary trading and EA development, many things became clear.

Even a single trading method experiences favorable and unfavorable markets.

Strong in trends.

Functions well in ranges.

Targets short-term price movements.

Aim for relatively large price movements.

Use characteristics of specific times or seasons.

And some logics have many entry opportunities, while others wait longer for conditions to line up.

So I began to think,

“Do we really need to capture all market environments with one logic?”

I started to think this way.

Rather than loading everything onto one EA,

A plays to its strengths in its area.

B plays to its strengths in its area.

C complements where A and B struggle.

Combining EAs with different roles feels more natural for my trading approach.

This is connected to my current portfolio philosophy.

That’s why I have always thought of EAs in terms of “genres”

In fact, this approach did not originate suddenly recently.

Before, on Investment Navi+, I wrote

“Specifically categorize Reiwa Double-E’s EAs by genre.”

In that article, I explained how I categorize the EAs I’ve developed.

There, I divided the EAs I developed into

・Scalping (pullback buying, pullback selling)
・Scalping (mean reversion)
・Anomalies (scheduled trading)
・Morning scalping
・Trend following
・Swing
・Breakout
・Nampin
・Proprietary logic
・Multi-logic

to illustrate them.

Why did I do this?

The reason is simple.

I don’t see EAs as single products to be used alone, but as components to be combined in operation.

Rather than favoring only similar-type EAs, I mix those with different characteristics.

When I think about a portfolio, I also value this “genre” perspective.

However, different genres are not inherently safer

This is also very important.

Diversifying genres alone does not automatically complete risk management.

Conversely, even within the same scalping genre, technicals, filters, entry conditions, and exit conditions can be completely different.

Even with different logics, if you are looking at the same market, you may end up entering around similar times.

So I think,

“Moving many different EAs does not necessarily make a portfolio by itself.”

The elements to consider include genre, logics, currency pairs, time frames, entry frequency, holding duration, P/L movements, and simultaneous holdings, among others.

You must consider these multiple factors when planning actual operation.

Therefore I have long emphasized risk management

Before combining EAs, you must first consider how much risk each EA takes individually.

I’ve written about this before,

“How to calculate EA risk management”

in an article.

■「EAのリスク管理の計算方法」について
https://www.gogojungle.co.jp/finance/navi/articles/64703

This article explains that

rather than one-size-fits-all advice like “this EA should use ○ lots,”

it is essential for users to calculate their own risk and determine the lot size they can tolerate, since funds and risk tolerance vary among users.

Check the maximum drawdown and required margin from backtests,

consider, “What amount of capital could this lot cause to vary by?”

Then decide what range you can personally tolerate.

I believe this is very important in EA operation as well.

“EA selection,” “risk management,” and “portfolio diversification” are all connected

Looking back, to me, these are not separate topics.

EA development

EA selection

Risk management

Genre diversification

Portfolio

They are all connected.

Everything is linked.

What edge did you aim for when creating an EA?

What market conditions does that EA excel in?

What market conditions does it struggle with?

What level of risk do you operate at?

How does it complement other EAs when combined?

All of these are part of my current EA operation.

I don’t build EAs to simply increase the number of products

I’d like to state this again.

I develop many EAs not to increase the number of products per se, but to explore how they can be combined and operated.

From a discretionary trader’s perspective, I look for features like,

“this area has this characteristic”

“could this be targeted in another way?”

I convert that into logic.

I test it.

I operate it as an EA.

As a result, many different EA types emerge.

My strength in EA development is

“finding an edge from the market and shaping it into logic”

So there are both scalping and anomalies.

There are trend following and swing as well.

Additionally, there are logics that do not fit neatly into any single category, or EAs that combine multiple logics.

And I actively operate them myself

What matters to me is that creating an EA is not the end point.

I also actually operate the EAs.

Then I notice things that aren’t obvious from backtests alone.

“These two tend to hold positions in the same market more than I thought.”

“Another EA compensates when one is underperforming.”

“Even though the logics are different, the risks can concentrate at the same timing.”

I learn these from real operation.

Then I return to design.

Develop.
Test.
Operate myself.
See results.
Improve.

I continue this cycle.

Recently I’m also considering controlling the portfolio itself

Furthermore, I’m taking it a step further and thinking about designing the risk of multiple logics combined, not just a single EA.

For example, suppose there are three different scalping logics.

Usually, each enters at different times.

But in certain markets, all three may meet the conditions at the same time.

Even if they are different logics, from the user’s account perspective, positions in the same direction may rise at once.

Then, for example,

one approach is to embed multiple logics into one EA and assign a priority to limit to a maximum of one position when all conditions are met

This is a possible approach.

Of course, it does not guarantee better performance.

Profit may decrease.

Or drawdown may be smaller.

So I will also test this.

If the results are truly effective, I’ll adopt it.

If not, I’ll consider another method.

I developed it myself, operate it myself, and arrived here

My portfolio philosophy wasn’t simply adopting a textbook finished form from the start.

I traded discretionary trading,

I created EAs,

I backtested,

I watched forward tests,

I operated them myself,

I made mistakes,

I asked, “How can this be improved further?”

And as a result, I arrived at my current thinking.

And I will likely continue to evolve.

I don’t think, “Now that it’s complete, don’t think about it anymore.”

New EAs will bring new discoveries.

If you actually operate them, you’ll find more improvements.

What I want to convey to users is not just the answers

That’s why I’ve written about risk management before.

I think it’s more important for users to be able to reason,

“Please run this EA at this lot size.”

Rather than simply giving that answer,

it is more important in the long run for users to be able to think for themselves about why that lot is chosen

and to understand the portfolio in the same way.

It isn’t a simple matter of, “If you combine this EA with that EA, you’ll win.”

Know the features of each EA.

Know the risks.

Consider your own capital.

Think about how much loss you can tolerate.

Then make your own judgment.

As a developer providing EAs, I want to convey not only the EAs themselves but also

the mindset for long-term operation of EAs as well

I’d like to share that as well.

In conclusion

There is no absolute in EAs.

I don’t believe there is a single thing that is the “correct answer” for a portfolio.

What I’ve written this time is not saying,

“Please do the same.”

It is,

“Reiwa Double-E has been designed by developing and operating EAs ourselves, testing and improving iteratively, and currently this is the approach to EA and portfolio design.”

From now on,

Look at the markets.
Search for edges.
Turn them into logic.
Test them.
Operate them in practice.
And improve.

I will continue to value this cycle.

Not only creating EAs, but

considering how users can run them sustainably and with ease

is part of my EA development for Reiwa Double-E.

That is my philosophy.

【How to choose an EA】

Now that you’re ready to operate an EA,

you may think, “I don’t know which EA will win… I don’t want to lose.”

That’s why Reiwa Double-E developed a series of articles with backtesting to gauge the pros and cons.

The following articles were published.

--------------------------------

https://www.gogojungle.co.jp/finance/navi/series/1714

----------------------------------

Actual performance vs forward results are important, but backtesting backs them up.

Backtests usually cover longer periods than forwards

and whether you are winning forward by luck can be inferred by refining backtest evaluations.

【EA risk management, how to handle?!】

Also, even if you obtain an excellent EA, neglecting risk management leads to ruin in EA trading.

So for EAs, how to manage risk?

This is addressed in the following article.
