Build arithmetic/geometric grid ladders with per-grid net profit after commissions and stamp tax, plus the break-even step.

Commission (%, each side)

Stamp tax (%, sell only)

Per-grid profit = buy at one grid, sell at the grid above, after two-way commission (min ¥5) and sell-side stamp tax. Slippage, 100-share lot rounding and price gaps are not modeled. Grids suit range-bound markets; trends cause persistent drawdown or missed upside.
