Bid / Ask
Also called: bid price, ask price, bid/ask
The bid is what the market will pay you to sell; the ask is what the market will charge you to buy.
During the Aug 2019 JPY flash crash, USD/JPY's bid-ask gap widened to over 400 pips for a few minutes โ the market effectively stopped functioning while liquidity dried up.
