Can you make money day trading?
Yes — a small minority of day traders genuinely do come out ahead, and a skilled few do very well. The honest question is how small, because almost everything written about it is either folklore or a scare number with no source behind it. In the largest studies of real brokerage accounts, most day traders ended up behind, and fewer than one in a hundred finished reliably ahead of fees, year after year, once costs were counted. Here is what the research actually found — named, dated and quoted, the numbers exactly as their authors reported them — and, up front, the one thing our own engine can and cannot test.
First — what we did not measure
One thing up front, because it is the honest core of this page: we did not measure any of this ourselves. Our engine runs on daily bars — one price per day per asset — and tests mechanical rules that act only on a closed bar. Day trading happens inside the day, on minute-by-minute data, often on leverage and on instruments we do not touch, so we cannot test it and we will not pretend to. Everything here is external evidence — peer-reviewed studies and a regulator's own figures, named and quoted so you can check each one yourself. The one adjacent thing we do measure, we show at the end, and keep it clearly bounded.
What the research actually found
In the largest study of real day-trading accounts — every day trader on the Taiwan Stock Exchange from 1992 to 2006 (Barber, Lee, Liu and Odean, Journal of Financial Markets, 2014) — the authors found that “less than 1% of the day trader population is able to predictably and reliably earn positive abnormal returns net of fees.” A separate study of Brazilians who tried to day-trade equity-index futures for a living and stuck with it past 300 trading days (Chague, De-Losso and Giovannetti, a 2019 working paper, not yet peer-reviewed) found that “97% of them lost money, only 0.4% earned more than a bank teller (US$54 per day), and the top individual earned only US$310 per day with great risk (a standard deviation of US$2,560)” — and no sign that traders learned to do better over time.
The skilled minority, in real numbers
The skilled minority in that Taiwan study is worth naming: ranked by the prior year's results, the top 500 day traders went on to earn about +37.9 basis points per day after fees (about +61.3 before) — a true and persistent edge for a very small group — while the lowest-ranked lost about −28.9 basis points per day after fees. A few people clearly do clear the bar; they are simply far rarer than a screen full of winning testimonials suggests.
The number everyone gets wrong
Two numbers get mixed up constantly, and the mix-up is where the dishonesty usually lives. In a typical year, roughly one in five active day traders finishes ahead of fees — not nobody. But doing it reliably, year after year, is where the figure collapses below one in a hundred (Barber, Lee, Liu, Odean and Zhang, follow-up work on the same Taiwan data). “About one in five is ahead this year” and “almost no one can do it dependably” are completely different claims, and only the second is what the strongest evidence shows.
The research also found most do not stay: more than three-quarters of all day traders quit within two years, and the worst performers are the likeliest to leave — though many keep going well past the point the numbers justify.
Why the odds are this steep
Why are the odds this steep? Costs compound on every fill, and day trading means far more fills than ordinary investing — each one paying spread and commission. You are trading against professionals and algorithms, so after costs the activity sits close to negative-sum. Noise dominates the signal at intraday horizons. And leverage, common in day trading, magnifies the losses as readily as the gains. None of that makes a durable edge impossible — it makes one rare.
One famous study gets dragged into this debate but does not belong: Barber and Odean's “Trading Is Hazardous to Your Wealth” (Journal of Finance, 2000) measured 66,465 US households' portfolio turnover from 1991 to 1996 — not intraday day trading. The households that traded most “earn an annual return of 11.4 percent, while the market returns 17.9 percent,” so the heaviest traders underperformed the market — but they did not lose money; the gap was trading costs, not bad stock-picking. Read it as a caution about overtrading, not as a day-trading loss figure.
What the regulators actually say
And the folklore: you will see “90% of day traders lose” — or 95%, or 80%, or the “90-90-90 rule” — repeated everywhere, often pinned on the SEC or FINRA. Those regulators publish no such figure; they warn in words, telling would-be day traders to “be prepared to lose all of the funds” they trade with, not in percentages. We will not repeat a number with no source behind it, even though it would make the point louder.
The one hard regulator figure nearby measures a different instrument. Europe's markets authority (ESMA, 2018) reported that “between 74% and 89% of retail accounts typically lose money” trading CFDs — leveraged derivatives, a distinct and higher-risk product, not the stock or futures day trading the studies above measured. It sits alongside the academic evidence, not blended into it.
Where our own data fits
Where does our own data fit? At the edge of this question, not the centre. Our engine cannot trade intraday, but it has measured how often famous mechanical rules beat simply holding on daily bars — and even on that slower, cheaper ground, most fell short: of the famous mechanical rules tested on US stocks in our frozen, open census, 721 of 839 judged backtests (86%) lagged simply buying and holding the same asset, net of costs. Day trading is faster, pays more spread and fees across far more fills, and acts on noisier signals — so if the slower, cheaper version mostly falls short of holding, the intraday version faces a steeper hill, not an easier one. That is a hint pointing the same way as the external studies — not a measurement of day trading, and not proof; a different instrument, tested a different way, could in principle behave differently.

So — can you? The honest read
So — can you make money day trading? On the honest evidence: a few people clearly do, including a skilled minority with a true and persistent edge, and almost everyone else does not. Most lose, most quit inside two years, and earning a dependable living from it is rare enough that the best studies measure it in fractions of a percent. That is not the same as saying it is impossible, and it is not the easy, dependable money it is often sold as either. It is a cost and a probability, laid out honestly for you to weigh — not a nudge to try it, and not a nudge to avoid it.
This is not “day trading is impossible” — a skilled few clear the bar, and the question deserves a straight answer rather than a folklore statistic. It is that the base rate is unforgiving and the costs never sleep, so the honest move is to test what can be tested before risking actual money.
Day trading is intraday, so we cannot test it for you — but you can test the daily-bar strategy ideas most aspiring day traders are sold around, the honest way: costs charged on every fill, no hindsight, measured against simply holding. Free, no sign-up.
If a funded-account challenge is the route you are weighing, the honest first step is whether the strategy you would run would even survive its drawdown rules — most challenges are lost to those rules, and the firm keeps the fee. Check a strategy against prop-firm rules →
Limits
This is a synthesis of external research, not our own measurement of day trading — our daily-bar engine cannot test intraday at all. The studies cover specific markets and periods (Taiwan equities, Brazilian index futures, US household accounts, European CFDs); each is one honest but partial window, and none is the last word. The one first-party figure here is survivor-only, one roughly five-year window, no out-of-sample split, and not significance-tested — a bounded analogy, held in its lane.
