We at Shares do not charge you any commission for any of your trades.
You will, however, be subject to an FX fee (foreign currency exchange fee), which is mandatory for all trades.
This fee is charged because all the securities available on our platform are from the NASDAQ and NYSE (Stock exchanges from the United States of America), where the default currency to trade any security is US Dollar($). You will be subjected to the FX fee for this conversion between Pound sterling(£) and US Dollar($).
Before purchasing any stock, you will receive an estimate just before confirming the order.
This estimate will provide all the costs included, where you can find the FX fee for the particular transaction as well.
