Good old article, however, trading is a bit of a hybrid.
If you are staging orders on the exchange order books latency is moot. Your quotes and order updates are subject to latency but your pending orders rest and process directly on the exchange servers.
If you are placing market orders from your PC latency applies.
Quotes are subject to latency. If your using broker simulated order types... ie trailing stops these orders rest on your broker's servers subject to their latency to the exchange.
