Transaction costs may vary depending on the broker with whom a client does business. Also, the fees vary according to time of day and type of currency that is considered.
Example: You can find a broker with 3 pips between supply and demand for all transactions between EUR and USD but this gap will be 10 pips during the weekend.
Transaction costs are not always given for each transaction, but it may be possible to make a good approximation.
The rule is to take the difference between the bid price and the ask price for the sale and purchase and take the average. Must be multiplied by the value of the leverage and the amount invested.
Formula
EcartVente = EcartAchat = PrixAsk - PrixBid
Costs (pips) = 0.5 * (+ EcartVente EcartAchat)
Costs ($) = 0.5 * (+ EcartVente EcartAchat) * (currency ($) / 10000pips) * Lever * Amount * conversion
Example: For our example transaction where we used U.S. $ 1000 with a leverage of 100 to 1 we find the value of costs and profit made by the broker.
EcartAchat = EcartVente = 3 pips
Costs ($) = 0.5 * (3 + 3) * (1EUR/10000) * 100 * $ 1000 * ((USD / EUR) / 1.2096
Costs ($) = 20.67 USD
