E*TRADE allows investors to trade stocks, bonds, mutual funds, ETFs, options and futures. The company does not offer currency or cryptocurrency trading, nor does it allow investors to trade fractional shares. The foreign exchange market (forex) is a market in which the world's currencies are traded 24 hours a day. For some, it's simply a mechanism for exchanging one currency for another.
Multinational corporations doing business globally rely on these markets to exchange currencies from around the world. The market is also occupied by traders who bet on the movements of currencies against each other. Exchange traded funds (ETFs) and exchange-traded bonds (ETNs) are traded like stocks and can be a way to invest in currencies without the need to trade in currencies.
