Essentially, the tighter the spread, the lower the cost of trading. The wider the spread, the higher it costs.
For example, let’s say EURUSD is quoted with a buy price of 1.0984 and a sell price of 1.0983. The spread can be calculated by subtracting 1.0983 from 1.0984 – giving a total spread of 0.0001 or 1 pip.
At Place a Trade, prices are quoted up to 5 decimal points.
