The real BTC/USDT market over this period was violent: a low of $58,625, a high of $124,659, a median of $84,260, and a current price of only $63,000. That is a 2.13x top-to-bottom swing and a roughly 50% drawdown from the peak by the end of the window. Any strategy that claims to handle this kind of two-sided volatility deserves scrutiny.

This analysis sweeps 35 grid configurations — seven range half-widths from ±10% to ±50%, and five grid counts from 20 to 200 — using Binance historical data over the past 365 days. The result is unambiguous: the best cell produced **14.4% annual ROI with a ±50% range and only
