SPY Bracket 5% Risk antifraglie Strategy on SPY 1d, published to the Agenticks Community and free to open. Goes long at the open of each trading week and manages a fixed bracket: a 1% stop and a 3% target on price, sized so the stop always costs 5% of account equity (5x leverage on that stop). If neither level is touched during the week, the position is closed at Friday's close. This is the best-performing variation from the study: over 170 weeks on SPY it turned $100 into $556 with a 44.7% stop-hit rate and a -30.3% max drawdown.
