Grid strategy on SOL/USDT during a 15.95% downtrend. 📈

Range: $122.68–$147.48 | 20 grids | Arithmetic spacing | $50/grid | 2% profit target | 0.1% fee

Result: +9.27% ROI, $92.71 net profit, 348 trades over 44 days.

Why it worked: the 7-day range calibration placed the grid exactly where SOL was oscillating. An A/B/C test confirmed this — 7-day range outperformed 30-day variants by roughly 2.4x in ROI.

Why it wasn't free money: 40% of capital ($399.88) ended idle in cash, and max drawdown reached 26.64% - higher than SOL's actual price decline, because the grid accumulated inventory on the way down.

Grids don't need price to rise. They need price to move and reverse. A one-directional trend with no bounces breaks the model entirely.
