Any quotation - or reverse - the client is selling the base currency at the rate of Bid and Offer (the highest rate). The difference between Bid and Offer rates is called the spread (Spread - the difference between the rates of Bid and Offer). Naturally, the customer is always beneficial for a small spread. Banks are more willing to work with a small spread, when the currency has high liquidity, and to a lesser extent, when the market volume of trade of the currency low. In this case, it is difficult to find a partner and close the currency position. For safety reasons, spread increases as compared to conventional markets in volatile markets, before the publication of important economic data due to political events

or at the end of the trading day.
