When you're making trades in the forex market, you're basically buying or selling the currency of a particular country. But there's no physical exchange of money from one hand to another. That's contrary to what happens at a foreign exchange kiosk—think of a tourist visiting Times Square in New York City from Japan. He may be converting his (physical) yen to actual U.S. dollar cash (and may be charged a commission fee to do so) so he can spend his money while he's traveling.

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.
"Buy the rumor, sell the fact": This market truism can apply to many currency situations. It is the tendency for the price of a currency to reflect the impact of a particular action before it occurs and, when the anticipated event comes to pass, react in exactly the opposite direction. This may also be referred to as a market being "oversold" or "overbought".[75] To buy the rumor or sell the fact can also be an example of the cognitive bias known as anchoring, when investors focus too much on the relevance of outside events to currency prices.

Day trading also deserves some extra attention in this area and a daily risk maximum should also be implemented. This daily risk maximum can be 1% (or less) of capital, or equivalent to the average daily profit over a 30 day period. For example, a trader with a $50,000 account (leverage not included) could lose a maximum of $500 per day under these risk parameters. Alternatively, this number could be altered so it is more in line with the average daily gain (i.e., if a trader makes $100 on positive days, they keeps their losses close to $100 or less).
Alongside choosing a broker, you will also be researching the Forex trading software and platforms they offer. The trading platform is the central element of your trading, and your main working tool. It is an essential piece of the puzzle, as the best Forex tools can have a significant impact on your trading results. So, what should you be looking for when considering your options?
Hedge funds – Somewhere around 70 to 90% of all foreign exchange transactions are speculative in nature. This means, the person or institutions that bought or sold the currency has no plan of actually taking delivery of the currency; instead, the transaction was executed with sole intention of speculating on the price movement of that particular currency. Retail speculators (you and I) are small cheese compared to the big hedge funds that control and speculate with billions of dollars of equity each day in the currency markets.
Major Currency — currencies from the world’s most developed economies including Europe, Japan, Canada, and Australia — represent the most heavily traded and liquid currency markets for any forex trader. A major currency pair is created when one of these currencies is traded against the U.S. dollar. Examples include Euro vs. the U.S. Dollar (EUR/USD) and the U.S. Dollar vs. the Canadian Dollar (USD/CAD). Their availability on a forex brokerage is essential.
If you're day trading a currency pair like the GBP/USD, you can risk $50 on each trade, and each pip of movement is worth $10 with a standard lot (100,000 units worth of currency). Therefore you can take a position of one standard lot with a 5-pip stop-loss order, which will keep the risk of loss to $50 on the trade. That also means a winning trade is worth $80 (8 pips x $10).

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.
National central banks play an important role in the foreign exchange markets. They try to control the money supply, inflation, and/or interest rates and often have official or unofficial target rates for their currencies. They can use their often substantial foreign exchange reserves to stabilize the market. Nevertheless, the effectiveness of central bank "stabilizing speculation" is doubtful because central banks do not go bankrupt if they make large losses as other traders would. There is also no convincing evidence that they actually make a profit from trading.
Forex banks, ECNs, and prime brokers offer NDF contracts, which are derivatives that have no real deliver-ability. NDFs are popular for currencies with restrictions such as the Argentinian peso. In fact, a forex hedger can only hedge such risks with NDFs, as currencies such as the Argentinian peso cannot be traded on open markets like major currencies.[77]
Factors like interest rates, trade flows, tourism, economic strength and geopolitical risk affect supply and demand for currencies, which creates daily volatility in the forex markets. An opportunity exists to profit from changes that may increase or reduce one currency's value compared to another. A forecast that one currency will weaken is essentially the same as assuming that the other currency in the pair will strengthen because currencies are traded as pairs.
