What matters to me is the speed of order execution and the fact that they are executed without slippage.
I trade volatile financial instruments and at the same time my orders, stop losses and take profits are located quite close.
Therefore, it's important to me that my orders are executed without slippage and with maximum speed.
XS, it seems to me, uses technologies that ensure such a high quality of order execution. Btw, so far I haven't noticed any problems.
I really hope that this broker will continue to show high-quality order execution.
