Sometimes there is a small difference between the price of an Index at BUX X and the price of an Index in the market. There are a few things that can cause this.
We link the price of an Index to the "Future" of this Index, which often has longer opening hours. If the underlying "Future" products are closed, then we look at related products in the market and adjust the price accordingly. This way, we can offer certain Indices almost 24 hours a day.
The price of an Index on BUX X is almost always between the bid and ask price of the market and is the same for all BUX X clients.
