Definition - What does
Fast Market mean?
A fast market is a period of time when heavy trading volume is accompanied by a wider than normal range of price action. Essentially, a fast market is a trading session where prices move further and faster than normal.
Fast markets usually have a cause, such as a major news event like riots, war, disaster, economic surprises and so on. Market participants digest news events at different speeds and with different perspectives, so a single event will lead to very different trading positions being taken up and abandoned.
