DCA vs Grid Trading

DCA is mainly an accumulation method. It spreads entries across time or price levels so a trader does not depend on a single perfect entry.

Grid trading is mainly a market-making style execution pattern. It places repeated buy and sell orders around a range and depends on oscillation.

DCA risk grows when the asset keeps falling and the trader continues adding size. The key control is maximum allocation.

Grid risk grows when price trends away from the range. The key controls are range selection, inventory limits, and stop rules.

A DCA bot should make allocation limits obvious, because the easiest failure mode is adding more than planned.

A grid bot should make inventory and realized fees obvious, because small fills can look profitable before costs are counted.
