Everything here about trading VPS

A trading VPS is bought for one thing, and it is not the specs

The reason to pay for a server instead of running a terminal at home is physical distance to the venue you trade on. A well-specced, cheap VPS in the wrong city does not do the job it was bought for, which is why location outranks every other component in our VPS rating — and why the providers that win are not always the ones with the largest advertised hardware.

If you are running a bot rather than a terminal, two more things matter and are rarely mentioned: a static IP, because most exchange APIs want the key locked to one address, and uptime that survives a broker restart rather than a marketing SLA. Before renting anything, it is worth measuring what you actually have — our latency test runs from your own connection to five regions and takes under a minute.

The other honest answer is that plenty of people do not need one at all. A discretionary trader placing a few orders a day gains nothing measurable from twenty milliseconds, and several brokers give a free VPS at a deposit level that is cheaper than paying for one.
