Biggest losses on August 21, 2026
These are backtest data
How backtesting worksResolved trades are what a strategy gets scored on.
Every trade on this page has a known outcome, which is what makes it possible to measure a rule instead of guessing at one. Write a rule over trades like these and Rivo scores it: our longshot rule went 105 wins and 345 losses and still returned +67.5% at $100 a trade.
