The logistics of forex day trading are almost identical to every other market. However, there is one crucial difference worth highlighting. When you’re day trading in forex you’re buying a currency, while selling another at the same time. Hence that is why the currencies are marketed in pairs. So, the exchange rate pricing you see from your forex trading account represents the purchase price between the two currencies.
One way to deal with the foreign exchange risk is to engage in a forward transaction. In this transaction, money does not actually change hands until some agreed upon future date. A buyer and seller agree on an exchange rate for any date in the future, and the transaction occurs on that date, regardless of what the market rates are then. The duration of the trade can be one day, a few days, months or years. Usually the date is decided by both parties. Then the forward contract is negotiated and agreed upon by both parties.

Another important point for day trading is to choose a good Forex broker. The main attribute here is the spread and the commissions you have to pay. As a rule, a day trader executes a few transactions every day, and the cheaper this is for you, the more benefits you can get from day trading. Before choosing a brokerage firm, research their offers and track all of the possible expenses associated with day trading.

According to the Bank for International Settlements, the preliminary global results from the 2019 Triennial Central Bank Survey of Foreign Exchange and OTC Derivatives Markets Activity show that trading in foreign exchange markets averaged $6.6 trillion per day in April 2019. This is up from $5.1 trillion in April 2016. Measured by value, foreign exchange swaps were traded more than any other instrument in April 2019, at $3.2 trillion per day, followed by spot trading at $2 trillion.[3]
The main participants in this market are the larger international banks. Financial centers around the world function as anchors of trading between a wide range of multiple types of buyers and sellers around the clock, with the exception of weekends. Since currencies are always traded in pairs, the foreign exchange market does not set a currency's absolute value but rather determines its relative value by setting the market price of one currency if paid for with another. Ex: US$1 is worth X CAD, or CHF, or JPY, etc.
Cross Currency Pairs signifies secondary currencies traded against each other and not against the U.S. dollar. Examples include Euro vs. the Japanese Yen (EUR/JPY) or the British Pound vs. Swiss Franc (GBP/CHF). Most reputable brokers offer this category of trades, and it’s especially important for a forex trading account denominated in a currency other than the U.S. dollar, or for more advanced traders capitalizing on discrepancies between other economies.

If the velocity of your trades necessitates low fees, know that you will be sacrificing some educational resources in favor of a streamlined system designed for the pros. You’ll be jumping in with both feet. On the other hand, a low minimum account typically comes with the educational resources and communication channels required by new forex investors. The identity of different brokerages rest on the type of investors they aim to appeal to. Choose accordingly.
By contrast, the Australian Dollar, the New Zealand Dollar and the Japanese Yen tend to be more active between 00:00 and 08:00 GMT. As a trader, this means you can trade whenever it suits you - if you work during the day, there will be currencies available to trade before or after work. If you have children but are at home during the day, you can simply choose a different currency. In the Forex market, you can trade 24 hours a day, 5 days a week.

One unique aspect of this international market is that there is no central marketplace for foreign exchange. Rather, currency trading is conducted electronically over-the-counter (OTC), which means that all transactions occur via computer networks between traders around the world, rather than on one centralized exchange. The market is open 24 hours a day, five and a half days a week, and currencies are traded worldwide in the major financial centers of London, New York, Tokyo, Zurich, Frankfurt, Hong Kong, Singapore, Paris and Sydney—across almost every time zone. This means that when the trading day in the U.S. ends, the forex market begins anew in Tokyo and Hong Kong. As such, the forex market can be extremely active any time of the day, with price quotes changing constantly.
