The illegal brokering practice of trading on one's own behalf, based on advance knowledge of impending trades or recommendations, before informing or acting on behalf of one's clients.
Leading in a race or competition.
Supporting a political candidate, sports team, etc. because they are leading their race or competition.
Illegally making a trade for a personal account or a preferred customer’s account with the advance knowledge that a large order is in the market or will be coming to the market that likely will create a profit. Front running is possible in situations in which traders in the futures or stock markets trade both for their own accounts and their customers’ accounts, a practice known as duel trading. However, just because a trader engages in dual trading doesn’t mean that the trader is involved with front running.
Alternative spelling of front running.
