About
I'm Djosa. I trade CFDs and I built every calculator on this site.
I'm writing this because you should know something about the person giving you the numbers before you put your hard-earned money into a challenge. So let's get straight to it.
The first 18 months were mostly losing
A little over a year and a half ago I started looking into trading. It caught my attention, so I went deep — I read books, watched more courses than I want to admit, and traded other people's systems. Trader Tom's school run, an opening-range breakout, eventually months deep into ICT.
Then came months and months of not making money.
I didn't blow the accounts, because I traded small on purpose. But small losses are still losses. Setups that looked incredible on a chart I couldn't execute live, because reading every parameter in real time is a different sport than reading it on a replay.
What changed: simpler, then measured
I stopped trying to trade the most sophisticated version of what I'd learned and built the simplest one instead — one strategy I could actually execute under pressure. Back-tested, it landed close to the complex version at a fraction of the decisions.
Then I measured it until the numbers stopped being an opinion:
- 20,000+ trades back-tested by script
- ~2,000 trades back-tested by hand
- 500–1,000 trades forward-tested live
That's the part that separates a system from a hunch. Not the setup — the sample size behind it.
My numbers are mine. Don't copy them.
I take 70 to 80 trades a month at roughly 1 to 1.5 R:R. I'm not telling you to do that.
That's just what my strategy produced — it fires a lot of signals, and once I'd measured enough of them to trust the expected value, the math said take every one. Higher frequency on a small positive edge beats waiting all week for a perfect entry — at least for my system.
What I'd argue everyone should copy is the process, not the parameters: back-test and forward-test your own strategy until you know your real win rate, your real average win and loss, and how often it actually triggers.
Because that's when these calculators start meaning something.
Feed them guesses and you get a confident-looking guess back. Feed them numbers you've measured over thousands of trades, and you can finally answer the real question: does my edge survive this firm's specific rules, or not?
Why the calculators exist
Before you pay a few hundred dollars for a challenge, there's one number worth knowing: given your edge, your frequency, and that firm's specific drawdown rules — what are the odds you actually pass?
Nobody hands you that. Most calculators online divide the profit target by your average win and call it done. So I built the version I wanted: a simulator that runs thousands of accounts through the real rules — trailing drawdown, daily loss limits, time limits — and gives you the honest answer, even when the honest answer is low.
Every tool here shows how it works and where it stops working.
