High-frequency system, buy or not?

I decided to buy a trade adviser. The seller’s website says that an adviser is taken from an investment fund. The system is based on a variety of impulses in currency pairs. This is not a pure arbitrage, Transactions can last a long time. Do you think it is possible to buy such an adviser? I’m confused. There are many different offers

If this is a pure arbitration adviser, then do not buy. Now the arbitration advisers in the market do not work. All brokers have transferred the server to LD4 and they have good quotes. if someone has invented something new then you need to understand. What kind of counselor is this?
