Abstract: In this paper, we consider the pricing of liquidity risk in normal market. By employing the no-arbitrage idea of financial calculus and finance engineering, we discuss the pricing of market risk and liquidity risk under martingale measure, and obtain two separate market prices of risk for all tradable assets via the change of equivalent measure to make discounted assets into martingales, and then provide the pricing formula of liquidity risk premium, in which the market price of risk in the same market for all tradable assets and for all the investors is the same, not varying with the levels of risk aversion of investors.
