Taking a short break for a few days ☀️
It’s been a busy period full of testing, updates, and new ideas — time to recharge a bit before coming back with fresh energy.
I’ll still be checking messages occasionally, but development will pause until I return.
Thanks to everyone who’s been following my work lately, I really appreciate it.

Wrapping up the week still testing and refining a new idea 👀
It’s too early to say much, but this one might be something special — focused on a cleaner, smarter entry logic.
I’ll share more once it passes the first robustness filters.
Until then, it’s just me, a lot of charts, and a bit of coffee ☕

A quick note on Walk Forward testing — it’s one of my favorite tools for checking if a strategy truly adapts to changing conditions.
It’s not perfect, but it forces your system to prove itself on unseen data instead of just repeating the past.
It’s like asking your EA, “Can you still perform when the market doesn’t look like yesterday?”
That’s where the real robustness shows up.

Today I was thinking about how trading, especially automated trading, is a constant exercise in patience.
You can do everything right — the logic, the testing, the validation — and still face uncertainty.
That’s what makes this field so challenging and so rewarding at the same time.
It’s not about removing doubt, but about learning to work despite it.

This week I’ve been rereading “Trading in the Zone” by Mark Douglas.
Even after all these years, it remains one of the best books to understand the mindset behind consistency.
It’s not about signals or strategies — it’s about how you think when everything moves against you.
If you haven’t read it yet, it’s definitely worth it.

Version 1.3 of Granite Pitch XAU is now live!
This update fixes the issue with lot sizing and improves how orders are handled internally.
It’s a small but important step — stability first, always.
Thanks to everyone who took the time to report and share feedback, it really helps me refine each version.

This week was mostly about testing, tweaking, and watching data flow — nothing flashy, just steady progress.
I’ve started shaping a new EA idea that’s still too early to share, but it’s moving in a good direction 👀
Sometimes the best work happens in the background, before anyone sees it.
I’ll share more soon once it takes form.

People often say algorithmic trading has no emotions. True — the EA doesn’t.
But we, the developers, still feel every curve, every backtest, every failure that didn’t pass validation.
It’s funny how we write code to avoid emotion, yet we end up caring deeply about the logic we build.
I guess that’s what keeps this job human after all.

I was thinking today about how early this passion started for me — I began trading at 18 and always knew I was drawn to the technical side of it.
Even back then, I loved charts, structure, and the logic behind each decision.
It made me realize that trading is not just about profit, but about building something that reflects how you think.
What about you? How did your story with trading begin?

Some days progress feels slow — maybe just one cleaner backtest or a filter that finally makes sense.
But honestly, that’s how most real progress happens: quietly, one small piece at a time.
The big jumps come later, built on hundreds of those tiny steps that no one sees.
So if you’re building something, keep going — even the smallest improvements matter.

Lately I’ve been focused on building new strategies for the DAX, and to be honest… nothing solid has come out yet.
You follow the process, test everything properly, keep the parameters clean — and still, sometimes, it just doesn’t click.
It’s a bit frustrating, because it feels like doing all the right things without seeing results.
But I guess that’s part of the game: even when the data says “no,” the work is still moving you forward quietly.

Not every idea works — and that’s okay.I used to get frustrated when a strategy didn’t pass validation, but now I see those moments differently.Each “failure” is just another filter that keeps me from wasting time on something that wouldn’t last anyway.It’s a quiet reminder that progress in trading isn’t always about winning, but about refining what deserves to stay.And as always, friends — you know you can contact me anytime for questions or suggestions!

Lately I’ve been thinking that algorithmic trading teaches patience in its own quiet way.
You spend hours building something, and then… you wait. You wait for tests, for validations, for data to come in.
Sometimes days go by with nothing “exciting” happening — and that’s exactly how it should be.
I guess that’s the part that connects trading with real life: good things usually need time to prove themselves.

I was thinking today about how small details can completely change the outcome of an EA.
Sometimes it’s just one condition, one filter, or even a slight timing adjustment — and suddenly the whole behavior of the system transforms.
It reminds me that building strategies is not only about logic and math, but also about intuition and patience.
The fine-tuning stage is almost like craftsmanship: slow, precise, and full of small decisions that make a big difference in the end.

Most people only see the final result — a working EA on the Market.
What they don’t see are the weeks (sometimes months) of testing, fine-tuning, and discarding ideas that didn’t quite make it.
Behind every strategy that goes public, there are dozens that never will.
This invisible part of the work is what really shapes the quality of the final product.
It’s a quiet process, but it’s where most of the real progress happens.

Good news: both of my free EAs are finally back online!
The issue turned out to be a small mistake on my side, but the support team was quick and professional in helping me sort it out.
I really appreciate their efficiency — it’s good to know there’s solid technical assistance behind the platform.
Now everything is running smoothly again, and I can focus fully on building the next project.

Sorry for being a bit quiet these days — I was busy trying to sort out the issue with my free EAs.
As you can see, everything on MT5 is back now, and in the end it was just a simple typo mistake on my side.
Lesson learned! At least it’s fixed and the bots are available again.
And yes… new things are coming (as they say) — I’m already working on another EA and I’m quite excited about it.

My First Prop Firm Experience — And Why I’m Still Skeptical
27 septiembre 2025, 09:39
This week one of my EAs managed to pass a prop firm challenge. For me it was the first time trying this type of service — I had never used prop firms before. To be honest, I don’t really trust them, and even after passing, I still don’t (haha...

A bit frustrated today — my free EAs were removed again, and I’m not entirely sure of the exact reason.
Maybe it was a simple mistake in the description, or just a detail I overlooked.
I’ve already contacted the staff to clarify the situation and hopefully get them back online soon.
It’s a pity, because the idea was to keep them free for everyone to test and benefit from.
I’ll keep you updated as soon as I know more.

The first free release seems to have worked quite well — I’ve noticed more people trying it out and that gives me good motivation to keep going.
It’s encouraging to see that even a small step like offering a free EA can help others understand the work behind it.
I’ll continue looking for ways to make my projects more visible and easier to test.
Step by step, I think this approach can build a solid foundation.
