As the market enters a phase of "wider volatility bands and longer cycles," traditional narrow-range grid trading often encounters a practical problem: the price easily touches the boundaries repeatedly, requiring frequent parameter and range adjustments. This shifts trading from "automated execution" to "continuous manual maintenance." The TianDi grid is specifically designed for this market structure: using wider upper and lower boundaries to cover larger volatility ranges, allowing the grid to operate more stably over longer cycles and reducing the operational costs associated with frequent short-term parameter adjustments.

The TianDi grid does not alter the fundamental logic of grid trading—"layered order placement, order filling, and cyclic execution"—but enhances its "coverage capacity" and "durability." By setting a larger operational range in one go, the strategy can withstand repeated fluctuations within the range over a longer period, entrusting trading actions to rules rather than emotions and frequent interventions.
