Touchline(redirected from Touch Lines)
Also found in: Dictionary, Thesaurus.
The highest price a buyer of a security is willing to pay and the lowest price a seller is willing to sell at a given time. The touch line, like the bid-ask spread, represents the best price available for a security. Generally speaking, the more liquid an asset is, the lower the bid-ask spread is. As a result, currency, which is considered the most liquid asset, has an extremely low bid-ask spread.
