In High-Frequency Trading, Which Aggregation Method Is Preferred and Why?

Off-chain aggregation is generally preferred for high-frequency trading (HFT) due to its significantly lower latency and gas costs. HFT strategies require near-instantaneous data updates to execute trades profitably.

On-chain aggregation's inherent delays (due to block times) and high, variable gas fees make it unsuitable for the speed and cost-sensitivity required for HFT, where every millisecond and penny counts.
