Make a stupid EA to play
Hello. This is 2pay.
As the title suggests this time, I will create a stupid EA.
While browsing purchase sites for EAs, you’ll probably come across ones with 100% or 99% win rates.
I doubt whether they truly win, but even on the published forward tests they show growth, so they aren’t complete lies. However, they feel suspicious.
When I knew nothing, there were several times I impulsively wanted to buy. (In the end I didn’t buy any of them.)
So I’ve prepared it right away.
Real tick testing shows about five years of operation.
To convey the idea of a complete victory, I named it "Win_it_all." Names like "Valkyrie" or other cool-yet-juvenile-sounding names make it feel more authentic, doesn’t it?
When the win rate is 100%, the PF becomes unmeasurable and shows 0.

A superior AI finds the perfect entry points and enters at carefully selected timings.
It uses the most common indicator, the moving average, and does not depend on the broker you operate with.
It works with various cross-yen currency pairs.
It always holds only one position. It carries no risk of blowing up instantly like averaging down, so it is safe.
Since it never loses, you can operate it with peace of mind.

If you’re advertised something like that, wouldn’t someone who doesn’t know anything be happy to buy it?

Revelation
Hints to detect cheating are hidden in the performance section below.
Longest position holding time: 6408:13:28 (≈267 days)
Holding it for up to eight months.Did they tighten the fist with a machine vise?
This EA uses a very simple mechanism: once a position is held, it does not close until it reaches TP 10 pips.
(There is an SL set in the parameters, but it’s a dummy.)
Looking at the growth curve alone, assets seem to increase at a steady pace, but since 2023 the holding time has accounted for an overwhelmingly larger share.
The drawdown pattern matches the chart.
The entry condition is only the golden cross of MA25 and MA75.
The key is Buy only, and during the testing period (2020-2025) USD/JPY is in an uptrend.
Since the test ended near 156 yen, if you set a price level that can enter below 155 yen, you can stay ahead of the test end time.
No matter what tricks you use... in the end... as long as you win, that’s enough!
By the way, even if you change the entry timing from golden cross to dead cross, you still get a 100% win rate.
If the market condition is favorable, any entry factor will do, and by tweaking position sizing and money management a little, anyone can easily create an EA with 100% win rate.
For EAs that depend on indicators (a symmetrical logic regardless of direction), separating Buy and Sell leads to overfitting like this.
At the start of the year, purchases of EAs and indicators tend to rise.
Avoid or consult the seller before buying anything extremely suspicious.
I think the most effective is to show results of tests conducted over a period with similar start and end prices (e.g., USD/JPY from 2014-01 to 2020-12).
Directionally neutral and with lower volatility in the latter half. (Counter-trend EAs should be tested during the current trend.)
If an EA can truly win, it will withstand any market condition. An EA that cannot does not allow the user to exercise discretion, so understand that you cannot rely on it unconditionally.
GOLD-type EAs tend to be almost ruined by this.
This concludes the current content.
I will leave the source code of this EA (mql5) so you can play with it freely. (Selling is strictly prohibited)
I hope you enjoy the sense of complete victory and your purchasing desire is satisfied.
Thank you for reading.
