ETF 网格交易筛选器/参数计算器

About this Skill

This skill screens T+0 ETFs and LOFs suitable for grid trading and computes grid parameters (upper/lower bounds, grid spacing, base price) from public market data. A strict box-identification filter requires at least two highs forming an upper rail and two lows forming a lower rail, with price still inside the box; instruments without a real oscillation box or already broken out are excluded.
