All foreign exchange is the exchange rate between currency pairs. For example, pound against dollar and euro against pound. Otherwise, the exchange rate is meaningless. Risk can't be completely avoided. There is no risk but profit in any market, so please call me. In the foreign exchange market, the way to save profits and avoid risks is nothing more than hedging, forming your capital chain, putting the pound in different positions (the benchmark currency and the denominated currency), controlling the positions, and making plans to increase or decrease the positions. Only in this way can the principal be effectively preserved, at least not losing a lot. As for not losing at all, I don't think there is such a method in the foreign exchange market, and Soros and Buffett can't do it. It's just that they can minimize their losses if the amount of funds is large enough.
