Why Can't I Make Money Trading?

Is it really the stock picks?

Run one number before assuming it is. Your breakeven win rate is 1 / (1 + R), where R is your reward-to-risk ratio. At 1:1 you need half your trades to win just to break even. At 2:1 you need 1 in 3. At 0.5:1 — which is what taking profits early actually produces — you need 2 trades in 3.

That last one is where most of these investigations end, and it is worth being precise about why it goes unnoticed. Taking a profit early feels like removing risk: you banked something, and nothing can go wrong with money already in the account. What it actually did was raise the mark you have to clear, from half your trades to two in three. Your picking did not get worse. The pass mark moved, nobody announced it, and you went on grading yourself against the old one.

The pattern is not folklore. Barber and Odean tracked 66,465 households at a large discount broker from 1991 to 1996: the households that traded most earned 11.4% a year against a market returning 17.9%, while the average household earned 16.4% and turned over 75% of its portfolio annually.^[1] Activity was the variable that hurt.

What are the four failures?

1. Arithmetic nobody can do in their head

Breakeven win rate, expectancy, position size and risk of ruin decide whether a strategy works at all, whatever it trades — and none of them can be estimated by feel. That is not a failing; 1 / (1 + R) is easy to read and impossible to intuit.

The calculators run all four, free and with no account. Five minutes on your own numbers usually reframes the problem. Put costs in too: 300 round trips at $12 is $3,600 a year, which on a $25,000 account is 14.4% you must earn before the year starts level.

If the arithmetic says the strategy works, the next question is whether you actually traded it — and that is a record problem, not a maths one.

2. Rules broken quietly

Not defiance. Reinterpretation. The stop moves because the level "was never the real invalidation point", the size goes up because this one is "higher conviction", the loss is held because it is "a longer timeframe now". Each of those is a sentence written after the market moved, into a record that allows rewriting, and it feels at the time like accuracy rather than excuse.

This is the failure that compounds fastest, because it selectively removes the good outcomes: the rules you break are disproportionately the ones that were about to cost you something.

3. Information that cannot be graded

Following calls from a room, an account or a newsletter is not inherently a mistake. Following calls you have no way to grade is. If the losers are not published, the winners are not timestamped before the fact, and no one can check either without the seller's cooperation, then the record is unfalsifiable rather than good — and unfalsifiable records are the ones that get sold.

4. Publishing that leaks or proves nothing

Post an entry publicly in real time and you hand strangers a free option on your position. Post it after the fact and you have proved nothing, because everything in the screenshot was written after the market already answered. Traders oscillate between these two and conclude that the whole idea of a public record is worthless, when the actual problem is that both timings are wrong.

Which one is yours?

The diagnostic is uncomfortable but it is quick. Compute expectancy on your last 100 trades. If it is negative, the arithmetic is your problem and no better ticker fixes it. If it is positive but the account is flat, the gap is between the strategy and the execution, which means rules. If you cannot compute it at all because the record is incomplete or edited, that is the answer, and it is the one that has to be fixed first — you cannot diagnose a system you cannot observe.

Why does a record have to be unrevisable to be useful?

Because the trader is the one person who cannot audit their own journal. You already know what you meant to do, so a note that says you meant to do it reads as confirmation. What you cannot establish from inside an editable file is whether the version you are reading is the version you wrote before the fact.

Which is not a claim about your particular judgement — it is what shows up whenever anyone measures a population. Odean found that the stocks individual investors bought went on to underperform the ones they sold, so the trades themselves destroyed value before costs were counted.^[2] Across every investor in Taiwan, the aggregate individual portfolio lost 3.8 percentage points a year, with virtually all of it traced to aggressive orders rather than to stock selection.^[3] None of those traders thought picking was the problem either.

kappi is a trade recorder: you commit a trade before the fact, it is sealed on your device for a time-capsuled delay you choose, then kappi publishes it on a Merkle-anchored log. The seal is the whole mechanism — once a stop, a target and a thesis are sealed, revising them is no longer a private edit. $15/month, no free tier.
