Mykola began with a spreadsheet, a lot of trades, and an uncomfortable question: why did the same mistakes keep finding their way back into my account?
P&L could tell me whether I had made money. It couldn't tell me whether the decision was repeatable, careless, or just lucky.
01The blind spot
P&L was telling me what happened, not why.
I was trading, taking notes, and trying to be disciplined. On green days, the plan looked brilliant. On red days, I could always find a reason the result didn't really count. The spread was ugly. The entry was late. The market was weird. Memory can be very helpful when it wants to protect your ego.
I didn't need another pep talk. I needed a record that was harder to negotiate with: the actual entries and exits, fees, timing, direction, setup, and the decisions around them.
02The spreadsheet
It kept getting wider. My understanding didn't.
The first answer was a spreadsheet. I added columns for symbols and setups, then more columns to explain the first columns. It looked satisfyingly serious. For a while, that was enough to make me feel as if I was doing the work.
But every useful question became another round of sorting, copying, and checking formulas. The journal also depended on me retyping the trades I least wanted to revisit. Any system that needs perfect discipline is most fragile on the days when discipline is already in short supply.
03The questions
I wanted my own fills to disagree with me.
I wanted to know which setups still worked after fees, which symbols quietly drained the account, whether mornings were actually better than afternoons, and whether a winning trade had followed the plan or merely rescued a bad decision.
Those sound like simple questions. They weren't. The answers were scattered across broker exports, notes, and whatever version of the story I happened to believe that day.
I wasn't looking for a prettier dashboard. I was looking for fewer places to hide.
04The first version
So I started with the least glamorous part: the trades.
Import the executions instead of retyping them. Keep the fees. Preserve the timing. Review a day while the decisions were still fresh, then zoom out across a week, a quarter, or a year and see which patterns survived a real sample.
That became Mykola. Each useful part grew from the same rule: connect results to decisions, setups, risk, and consistency; keep the evidence auditable; and make the next adjustment specific enough to carry into the next session.
The test for adding anything new is still simple. If it can't help answer “What should I repeat, stop, or test next?” it probably doesn't belong on the screen.
05The practice
More statistics were never the point.
A journal cannot make a red trade pleasant, and it shouldn't try. What it can do is turn a vague bad feeling into something specific enough to work on.
Sometimes a review shows a good decision that happened to lose. Sometimes it shows a profitable day held together by sloppy risk. The second one is much more annoying. It is also more useful.
The aim is modest on purpose: finish the review with one measurable change, carry it into the next session, and let the next set of trades answer back.

The name
Mykola
Миколаproper noun · a given name
Born in Ukraine. Built in Berlin.
Mykola is my legal name. I was born in Ukraine, and it is the name I carry from there to Berlin. When the product needed a name, I kept circling back to the obvious one.
I hesitated. Naming a piece of software after yourself feels a little like signing the cover before you've filled the notebook. But the awkwardness was useful: it made the standard personal. If my name was going on it, the work had to be something I would trust with my own trades.
“Mykola” (Микола) is the Ukrainian form of Nicholas — common at home, unusual on a SaaS landing page. That tension fits. Mykola is meant to feel like a serious working journal: clear, honest, and close to the decisions that made the numbers.
The promise
A useful journal shouldn't flatter you.
It should keep the trade as it happened: the fill, fee, timing, setup, risk, and note you left before hindsight started editing.
Then it should help turn that evidence into one measurable change for the next session. No promise of easy profits. Just a clearer practice, repeated often enough to become honest.
The days I most want the journal to agree with me are usually the days I need it not to.
Ready when you are
Bring the trades. Keep the evidence. Improve one decision at a time.
