An investor can profit from the difference between two interest rates in two different economies by buying the currency with the higher interest rate and shorting the currency with the lower interest rate. Prior to the 2008 financial crisis, it was very common to short the Japanese yen (JPY) and buy British pounds (GBP) because the interest rate differential was very large. This strategy is sometimes referred to as a "carry trade."
Big news comes in and then the market starts to spike or plummets rapidly. At this point it may be tempting to jump on the easy-money train, however, doing so without a disciplined trading plan behind you can be just as damaging as gambling before the news comes out. This is because illiquidity and sharp price movements mean a trade can quickly translate into significant losses as large swings take place or ‘whipsaw’.

As mentioned earlier, in a long trade (also known as a buy trade), a trader will open a trade at the bid price, and will aim to close the trade at a higher price, making a profit on the difference between the opening and closing value of the currency pair. So if the EUR/USD bid price is 1.16667, and the trade closes at the price of 1.17568, the difference is 0.00901, or 90.1 pips. (When trading a single lot, that would make a 901 USD profit).
Trading psychology is by far, the most overlooked aspect of profitable trading.  To say it another way, you can use many strategies to turn a consistent profit, but you cannot trade profitably if you have yet to master the emotional side of trading. There is no exception to that rule. You cannot turn a profit while revenge trading. You cannot turn a profit if you’re over-leveraging and doubling down to

Forex trading beginners in particular, may be interested in the tutorials offered by a brand. These can be in the form of e-books, pdf documents, live webinars, expert advisors (ea), courses or a full academy program – whatever the source, it is worth judging the quality before opening an account. Bear in mind forex companies want you to trade, so will encourage trading frequently.
Most developed countries permit the trading of derivative products (such as futures and options on futures) on their exchanges. All these developed countries already have fully convertible capital accounts. Some governments of emerging markets do not allow foreign exchange derivative products on their exchanges because they have capital controls. The use of derivatives is growing in many emerging economies.[57] Countries such as South Korea, South Africa, and India have established currency futures exchanges, despite having some capital controls.
The blender costs $100 to manufacture, and the U.S. firm plans to sell it for €150—which is competitive with other blenders that were made in Europe. If this plan is successful, the company will make $50 in profit because the EUR/USD exchange rate is even. Unfortunately, the USD begins to rise in value versus the euro until the EUR/USD exchange rate is .80, which means it now costs $0.80 to buy €1.00.
Since the market is made by each of the participating banks providing offers and bids for a particular currency, the market pricing mechanism is based on supply and demand. Because there are such large trade flows within the system, it is difficult for rogue traders to influence the price of a currency. This system helps create transparency in the market for investors with access to interbank dealing.
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.
Set realistic trading goals: It's important to be realistic with your trading expectations, as this will help you assess the best times to open and close trades. Many new Forex traders have very high expectations about their potential profits, and this causes them to trade very aggressively, with large sums of money and fast decisions. Again, start small to test your knowledge and skills, and as you start to reliably achieve the results you want, you can set bigger goals.

Spread: The spread is the difference between a currency pair's bid and ask price. For the most popular currency pairs, the spread is often low - sometimes even less than a pip! For pairs that aren't traded as frequently, the spread tends to be much higher. Before a Forex trade becomes profitable, the value of the currency pair must cross the spread.

Unlike stock markets, which can trace their roots back centuries, the forex market as we understand it today is a truly new market. Of course, in its most basic sense - that of people converting one currency to another for financial advantage - forex has been around since nations began minting currencies. But the modern forex markets are a modern invention. After the accord at Bretton Woods in 1971, more major currencies were allowed to float freely against one another. The values of individual currencies vary, which has given rise to the need for foreign exchange services and trading.
