Founder & Lead Analyst at RinTrade
Sakkarin Grinara
I test Forex brokers so you can choose with evidence, not hype.
Hi, I'm Sakkarin. I check what brokers claim against official sources, test real trading setups myself, and publish the data so you can check my work too. My goal is simple: help you tell evidence from marketing.

Why I research brokers
I started learning about the markets more than ten years ago. Early on, I lost a trading account because I worked out my lot size wrong. It was a basic mistake, and it changed how I think. Risk, precision and clear explanations stopped being theory. They became the way I work.
I studied Finance and Banking at undergraduate level, and a stock market simulation during my studies is what first got me hooked on analysing businesses. I'm still a long-term stock investor, and I follow value-investing principles.
So when I look at a broker, I don't just see a trading platform. I see a business, and I want to check its claims, its costs and how it protects its clients.
One wrong lot-size calculation cost me a trading account. That's why I check the details.
What I do at RinTrade
RinTrade is the research site I'm building for people who want to see how a conclusion was reached, not just the conclusion. Here's what that means in practice.
I check facts at the source
Broker facts are matched against the broker's own documents and the regulator's records, and the date I checked them is shown on the page.
I test real trading setups
Every result keeps its account type, server, platform and test window attached, so you know exactly what was measured.
I publish my working
Methodology, cleaned data and checksums are public, so anyone can inspect the research and repeat it.
I hold back when the evidence is thin
If the evidence isn't strong enough yet, I don't publish a score or a fast-changing fact. A gap is better than a guess.
How I approach the work
Four rules I follow on every page I publish.
- 01
Start with the exact question.
A spread test, a safety review and a country check each need different evidence. I decide what I'm answering before I collect anything.
- 02
Keep the source next to the claim.
Facts that change often need a source and a check date, not a sentence that just sounds confident.
- 03
Be honest about the limits.
A short market sample is a snapshot of one period. A quoted price is not the same as what a trade actually costs.
- 04
Make the result repeatable where I can.
For data studies, I publish the cleaned inputs, the calculations and how I validated them, so you can check the numbers yourself.
Research I've published
My published broker rankings, each with the date it was last updated.
How I stay independent
RinTrade may earn a commission when you use some of our broker links. That's how the site pays its way. It never decides which brokers I measure, how they rank, or whether a claim is marked as verified. A partnership is not evidence, and I never treat it as one.
Broker terms and rules can change. Read each review together with its source dates and limits, and before you open an account, check which broker entity and protections apply in your country.
Want the full detail? Read our methodology and editorial policy.
Don't take my word for it. Check the evidence.
If a RinTrade page gives you a conclusion without enough evidence behind it, treat that as a reason to question the page, not to trust the conclusion. And if you find one, I'd like to hear about it.
