What is the difference between fixed and variable spreads?

Assets on TBanque are offered with spreads that are either “fixed” or “variable.”  As the name suggests, fixed spreads have a fixed-width spread where the difference between the BUY and SELL prices remains constant, regardless of the change in the price of the product. Conversely, variable (sometimes referred to as “floating”) spreads have a spread where the difference between the buy and sell prices may change.
