#06 EA amazing! undefeated!
October 29, 2025: Record
EA tested by changing various external parameters,
and when I set it to the values that produced the best results, .........
the profit factor dropped to zero!
As I mentioned in the previous issue, a profit factor above 1 is acceptable, and 2 is considered a very good EA.
So what does zero mean?
Profit Factor = Total Profit ÷ Total Loss
.
Why does it become zero?
→ Because the denominator is zero.
What does that imply?
→ It means there were no losing trades even once.
The test period was one year, and not a single loss occurred in that year.
However, since I also wanted to know the risk when losing, I kept increasing the investment amount.
Basically, I started with 100,000 yen in funds, and assumed 0.1 lots per position; with that setting, the annual profit was 25%, and I tested up to 0.3 lots by increasing by 0.01.
The result is ....
As I increased the investment amount, profits increased, and at 0.3 lots, the annual profit was 75%!
Since all figures were undefeated, I couldn’t test what would happen in a losing scenario...
(・´ω`・)
If you ask whether you earn more by investing larger amounts...
→ Well, in the market conditions from October 2024 to October 2025, yes. There were no losses at all.
But in the market, you never know what will happen.
Things like the Lehman Brothers collapse and the COVID turmoil...
Therefore, to prevent reckless users from taking risks, I eliminated all external parameters other than the EA's MagicNumber (the individual ID) and moved them inside the code.
I rewrote the code so that trading can only occur with 100,000 yen in funds and 0.1 lot per position (for 200,000 yen in funds, 0.2 lots).
In exchange for that!
I plan to rewrite the source into welfare trading/operating format.
Starting with 100,000 yen and 0.1 lot, when funds grow to 110,000 yen, I will set it to 0.11 lot.
And so on, increasing step by step.
