TradingBlog Diary dashboard: equity curve and emotional thermometer on a dark amber theme

Trading journal: without one, you’re trading blind

Your memory is lying to you. Ask a trader how the month went and the answer comes from feeling: “bad”, “so-so”, “I recovered near the end”. Almost always it is a softened, or dramatized, version of what actually happened. The brain remembers the two trades that hurt and forgets the twenty ordinary ones, and it makes the next decisions on that distorted memory.

The only antidote is to write it down. Not in words, in numbers and in states of mind. That is journaling, and it is the difference between traders who improve and traders who go in circles for years.

What a trading journal really is

A trading journal is not the profit and loss list your broker already gives you. It is the full account of every trade: when you entered and why, where your stop was, how much you were risking, what was going through your head at that moment and how it ended. With enough rows, you stop trading on feeling and start seeing patterns.

That is where the uncomfortable truths surface. That most of your losses come from a single instrument. That your best trades are the ones where you waited, and the worst are the ones where you jumped in off-plan. That the setup you “really like” has actually been losing money for months. You do not see any of this from memory, you see it only if you wrote it down.

The part everyone skips: the emotional journal

The market does not ruin you with technical analysis, it ruins you with your head. Yet almost no one keeps track of how they felt while trading, and that is a huge mistake, because the emotion you enter a trade with predicts the outcome better than almost any indicator.

Logging the mood of every trade, calm, anxious, euphoric, under pressure, and crossing it with the result, surfaces the most useful truth a trader can have about themselves: when you actually make money and when you are only hurting yourself. You might discover that your trades taken in a state of euphoria, right after a win, are systematically in the red. From that moment you hold a rule, not a hunch.

Stop repeating the same mistakes

A mistake you recognize while rereading it in black and white, next time you see it coming. The journal turns errors from recurring taxes into lessons paid once. Without it, you repeat the exact same mistake every two weeks, convinced each time that “this time is different”.

Know what to do in advance, and what you are really worth

With a complete journal you stop wondering whether a strategy works and start knowing. You see your real win rate, your average risk reward ratio, your expectancy, your best instrument and the one draining your account. It is no longer opinion, it is the precise pulse of your potential and your limits. And when you know the numbers, you know in advance what to do: what to push, what to cut, when to stop.

Win Rate: The Number That Is Lying to You

🤓 Nerd Mode

If I told you that your favorite trader on Instagram, the one flaunting a 90% win rate, could be losing money every single month, would you believe me? You should. Because the win rate, the percentage of trades closed in profit, is the most overrated and most misunderstood number in all of trading.

It is the number that makes you feel good while your account bleeds out. In this article I will explain why it is lying to you, and which number actually counts.

The win rate, on its own, tells you nothing

Picture two traders. The first wins 9 trades out of 10, but when he loses, he loses big. The second wins only 4 times out of 10, but when he wins he takes home twice what he risked. Who makes money?

It might surprise you, but it can easily be the second one. Because the win rate tells you how often you are right, not how much you make when you are right and how much you lose when you are wrong. And it is those two things together that decide whether you are in profit or in the red.

A 90% win rate with losses that wipe out ten winners is a machine for losing money in style. A 40% win rate with a good risk/reward ratio is a profitable system.

🧩 Explained Simply: expectancy

The number that really counts is called expectancy: how much you expect to make, on average, on each trade. The formula is simple:

Expectancy = (Win rate × Average win) − (Loss rate × Average loss)

If the result is positive, you make money over the long run. If it is negative, you lose, no matter how high your win rate is. Expectancy combines the two things the win rate ignores: how much you win and how much you lose.

Two systems, same profit, opposite win rates

Let’s take 10 trades, always risking 100 dollars per trade. Look at what happens with two different approaches:

System Win rate R:R Result over 10 trades
A 60% 1:1 6×100 − 4×100 = +200
B 40% 1:2 4×200 − 6×100 = +200

The exact same profit. But system B gets there while being right less than half the time. This changes everything on the mental side: if you do not need to guess much, you are far less exposed to frustration, revenge trading and the urge to force trades. A good risk/reward ratio buys you patience.

The minimum win rate you actually need

The good news is that, once you know your risk/reward ratio, you can instantly work out the minimum win rate you need just to break even. The formula is:

Minimum win rate = 1 / (1 + R:R)

Here is what it means in practice:

If your R:R is You only need a win rate of
1:1 50%
1:2 33%
1:3 25%

With a 1:3 ratio you only need to be right a little more than once in four to be in profit (exactly one in four already puts you at break-even, before spread and commissions). This is why experienced traders are obsessed with risk/reward and not with the win rate: they hunt for the few trades that offer a favorable ratio, and skip the rest.

What to do about it, in practice

Three concrete moves, right now:

1. Calculate your size before every trade. Expectancy only works if the risk per trade is constant. Before you enter, calculate the correct lot size based on capital, risk percentage and stop distance.

2. Track everything. You cannot improve what you do not measure. Log every trade, your real win rate, your average R:R and your expectancy. The TradingBlog Diary works them out automatically, complete with equity curve and Monte Carlo simulation.

3. Go deeper on money management. The win rate is just one piece of the puzzle. If you want the full picture, read Money Management Like a True Professional.
