There are no restrictions regarding the trading strategies, or any limitation about the use of EAs. I have been experimenting with trading robots lately and can recommend this platform and the MT4 trading app for this type of trading. They have a Cent account which is a perfect fit for trading with EAs. 👍
Also, I found the Elite account type great for scalping. The trading fees associated with this account type are relatively low and competitive if you compare them to other brokers.
In general, XS broker is reliable, versatile and trustworthy whatever your trading strategy or style is.
