Market makers continuously offer bid prices for trading instruments, which are generally lower than ask prices. The difference between bid vs. ask price is the spread and the profit a broker earns per transaction in a commission-free pricing environment.A trader looking to buy any asset must look at the bid price provided by a broker.
High liquidity results in a narrow spread in the bid price vs. ask price, while low liquidity widens the difference, making trading more expensiveBrokers source the price for each asset from numerous liquidity providers and market makers. Therefore, the actual buying and selling of trading instruments plus the trading volume determine the bid price formula.
Either the broker fills the entire order at the best price, in this case above 75, or the broker completes a partial fill and waits for the next bid at 75 to complete the order The difference between the bid price vs. the ask price depends on liquidity, where higher liquidity results in a narrow spread, which widens as liquidity fades.
