DCA and Grid Strategy Systems

DCA strategies schedule periodic buys/sells with configurable cadence, budget, and asset universe.

Execution checks include available permit budget, rate limits, and configurable pause conditions.

Grid strategies maintain layered orders around a reference price with spacing and quantity parameters.

State includes active grid levels, fills, and re-anchoring logic after major drift.

Both strategies must expose max allocation, stop triggers, and stale-data handling behavior.

Emergency stop and parameter hotfix paths should be available to operators.
