Do Most Day Traders Lose Money? A 3-Number Check Before You Fund the Next $2,000
You are about to add money to a trading account. Before you do, it is fair to ask the plain question. Do most day traders lose money?
The best public answer comes from a study of nearly every person who started day trading Brazilian index futures between 2013 and 2015. This guide covers what it found, what it does not say about you, and a three-number check you can do in ten minutes before you pay for the next attempt.
What the largest study actually found
Chague, De-Losso and Giovannetti (2020, "Day Trading for a Living?") followed 19,646 people who began day trading mini-Ibovespa futures. They then looked closely at the 1,551 who kept going for more than 300 trading days. After exchange and brokerage fees, 97% of those persistent traders lost money. Only 1.1% earned more than the Brazilian minimum wage, and 0.5% earned more than a bank teller's starting salary. The authors also found no evidence that traders improved with time.

Two cautions. It is one market in one country, and the authors say the results overstate profits because they leave out taxes, platform costs and courses. It also can't tell you how your own plan will do. The three numbers below are how you check that.
Why a plan can be right on average and still end your account
Expected value is an average. Your account lives through one sequence of trades, and the sequence includes losing streaks. The question is whether the plan survives the streak long enough for the average to show up.
That comes down to three numbers.
Number 1: risk per trade
This is the share of your account you lose when a trade fails. Plain arithmetic shows how fast it adds up.
| Risk per trade | Account left after 5 losses in a row | After 10 in a row | After 20 in a row |
|---|---|---|---|
| 1% | 95.1% | 90.4% | 81.8% |
| 2% | 90.4% | 81.7% | 66.8% |
| 5% | 77.4% | 59.9% | 35.8% |
At 5% per trade, ten losses leave you with about 60 cents on the dollar. At 1%, you still have 90.
Number 2: how long a losing streak you should expect
Losing streaks are not rare. These are exact calculations for 100 trades, assuming each trade is independent and the win rate is fixed.
| Win rate | 6 losses in a row | 8 in a row | 10 in a row |
|---|---|---|---|
| 50% | 55% | 17% | 4% |
| 45% | 73% | 31% | 10% |
At a 50% win rate, over 100 trades you should expect a run of six losses more often than not. If your plan can't take six, cut the size until it can. See the streak odds at 60%.
Number 3: what it takes to climb back
Losses are not symmetric. A 20% loss needs a 25% gain to get back to even. A 40% loss needs about 67%. A 50% loss needs 100%. This is why a deep hole is so hard to leave, and why many traders raise size to catch up, which makes the next streak worse.
Put the three numbers together
Pick the loss you would actually quit on. For most people it is lower than they first say, and that is fine. Then check the chain.
- Decide your quit line, for example a 20% drop in the account.
- Divide it by risk per trade. At 2% risk, 10 straight losses is about an 18% drop, which is close to the line.
- Compare that number of losers with the streak odds for your real win rate. If a streak that long is likely within the number of trades you take in a year, the plan is too big for the account.
If the answer is uncomfortable, lower the risk per trade and run the check again.
Where a simulation helps
A table assumes simple things. Your plan has its own win rate, win size, loss size and trade count. RangeSight runs thousands of simulated paths of the plan you enter and shows the chance of hitting the drawdown you set and the range of outcomes, including the weak end. It is an educational tool and does not predict returns. You can simulate your own plan.
FAQ
Do most day traders lose money?
In the largest public study of persistent day traders, 97% did after fees. That is one market and one period, but it is the reason to test a plan before funding it.
Does experience fix it?
The same study found no evidence of learning among persistent traders. That is a reason to check sizing and streak room rather than assume time will help.
What is a safe risk per trade?
There is no universal number. Use your quit line divided by the longest streak you want to survive. This guide shows the arithmetic, not advice.
Is this financial advice?
No. It is education about risk math. Past results do not predict future results.

Most persistent day traders in the largest study lost money. Before you fund the next $2,000, check three numbers: risk per trade, losing streak room, and recovery. RangeSight uses Monte Carlo simulation to show the chance of ruin, the chance of a drawdown, and the range of outcomes. It is not financial advice.
This explains the concept.
But outcomes vary in practice. The same strategy can produce a 40% gain or a 30% drawdown depending on trade sequencing and market conditions.
