“Fair point. Here are empirically established facts about trading: - **Most individual day traders lose money.** Studies of retail day traders in Taiwan and Brazil found that the large majority lost money after costs; only a small minority earned persistent profits. - **Past performance is not reliable evidence of future performance.** A profitable historical strategy can fail when market conditions, competition, liquidity, or execution costs change. - **Transaction costs reduce returns.** Commissions, bid–ask spreads, slippage, market impact, margin interest, and taxes are deducted from trading performance. - **Leverage increases both gains and losses.** A 10% adverse move against a fully leveraged 5× position represents approximately a 50% loss of the trader’s invested capital, before costs. - **Losses compound asymmetrically.** A 50% loss requires a 100% gain to return to the starting value; a 20% loss requires a 25% gain. - **A strategy can lose more often than it wins and still be profitable.** Profitability depends on expectancy, not win rate alone: \[ E=(p_w \times \text{average win})-(p_l \times \text{average loss})-\text{costs} \] - **A high win rate does not prove profitability.** A system that wins 90% of the time but loses ten times its average gain on the remaining trades has negative expectancy. - **Short-term price movements contain substantial randomness.** A correct market direction does not guarantee a profitable trade because entry timing, exit timing, spread, and slippage affect the result. - **Diversification reduces concentration risk.** Holding imperfectly correlated assets reduces exposure to a single company, sector, or market event; it does not eliminate losses. - **Survivorship bias distorts trading success stories.** Visible successful traders exclude the many unsuccessful traders who stopped trading or stopped reporting their results. - **Backtest results can be overstated by overfitting.** Testing many rules or parameters increases the chance that a strategy matches historical noise rather than a repeatable relationship. - **A trading system’s drawdown is a measurable fact, not an emotional judgment.** Maximum drawdown, volatility, win rate, average win, average loss, and net return can all be calculated from a complete trade record. - **No risk-management rule creates a profitable strategy by itself.** Position sizing can limit losses, but it cannot supply a missing statistical edge. - **Consistent profitability requires positive net expectancy over a sufficiently large sample.** A few winning trades are not evidence of a durable edge. The most defensible factual conclusion is: **profitability is possible, but most retail traders do not achieve it, and no general trading fact guarantees that an individual trader will be profitable.**”
Summary
Recent academic studies from Taiwan, Brazil and regulatory analyses confirm that 74‑97 % of retail day traders lose money, with only about 1‑3 % achieving sustained profits. The additional points about transaction costs, leverage effects, asymmetric compounding, expectancy, win‑rate myths, market randomness, diversification, survivorship bias, over‑fitting, drawdown measurement, and the limits of risk‑management are all consistent with established financial theory and empirical research. Consequently, profitability is possible but most retail traders do not achieve it, and no single trading fact guarantees individual success.

- The impact and profitability of day trading following the relaxation of day trading restrictions in Taiwan - ScienceDirect
The objective of this research is to investigate the impact and profitability of day trading following the relaxation of day trading restrictions in Taiwan, using time series models such as VAR models and EGRACH models. As a result of offering many essential hypotheses about this relaxation, we arrive at the following crucial conclusions. First, we demonstrate that a high market trading volume would result in a high day trading volume, which could be due to liquidity markets preferred by day traders, but a high day trading volume would not result in a high market trading volume, which could be due to speculative markets not preferred by other market participants.
