The spread can be calculated by subtracting the sell price from the buy price of the instrument, and can change whilst your position is open. Plus500 offers a fixed or dynamic spread for its instruments. The dynamic spread is constantly adjusted according to the market spread during the period a position is open, whereas the fixed spread does not typically change over time and general market fluctuations while a position is open. However, in cases of abnormal market conditions, the fixed spread may change to a new fixed level reflecting the applicable market conditions.
