# HFT mode

The HFT mode makes MetaCopier's own processing **5× faster**. The **internal copier latency** drops from the default **5 ms to 1 ms** per copied trade.

This is the part of the copy that MetaCopier controls. The network time and the broker execution time stay the same. For an explanation of all parts of the latency, see [Specifications](/features/specifications.md#latency).

Every copied trade passes through four steps: the network to MetaCopier, MetaCopier itself, the network to the slave broker and finally the slave broker, which opens the trade. HFT mode speeds up the MetaCopier step from 5 ms to 1 ms. The **broker execution time** (typically 50 to 500 ms) does not change, because it depends on the slave broker, not on MetaCopier.

This makes the HFT mode ideal for scalping and high-speed trading strategies, where every millisecond counts.
