International parity conditions: Relative purchasing power parity, interest rate parity, Domestic Fisher effect, International Fisher effect. Though to some extent the above theories provide logical explanation for the fluctuations in exchange rates, yet these theories falter as they are based on challengeable assumptions [e.g., free flow of goods, services and capital] which seldom hold true in the real world.
Traders know the news events that will move the market, yet the direction is not known in advance. Therefore, a trader may even be fairly confident that a news announcement, for instance that the Federal Reserve will or will not raise interest rates, will impact markets. Even then, traders cannot predict how the market will react to this expected news. Other factors such additional statements, figures or forward looking indications provided by news announcements can also make market movements extremely illogical.
The market determines the value, also known as an exchange rate, of the majority of currencies. Foreign exchange can be as simple as changing one currency for another at a local bank. It can also involve trading currency on the foreign exchange market. For example, a trader is betting a central bank will ease or tighten monetary policy and that one currency will strengthen versus the other.
The EUR/USD pair is closing a second consecutive week with gains at around 1.1070, retreating from a high at 1.1109. A scarce macroeconomic calendar kept the pair in a dull range during the first half of the week, also the wait and see stance ahead of the ECB monetary policy decision on Thursday. One done, one to go, as the US Federal Reserve will be announcing its decision on monetary policy next Wednesday, September 18.
Unless you understand the code it's written in, you're probably not going to be able to adapt your EA to work with those changes.

And perhaps best of all, we offer EAs free of charge for traders!
Diversify your portfolio: We all know the saying, 'don't put all your eggs in one basket', yet many new FX traders do this when it comes to their trading. Just as it isn't wise to put all of your funds into a single trade, relying on a single currency pair increases your level of risk, because if the pair moves in a different direction to what you expect, you could lose everything. Instead, consider opening a number of small trades across different Forex pairs.

The Forex martingale strategy: The martingale strategy is a trading strategy whereby, for every losing trade, you double the investment made in future trades in order to recover your losses, as soon as you make a successful trade. For instance, if you invest 1 EUR on your first trade and lose, on the next trade you would invest 2 EUR, then 4 EUR , then 8 EUR and so on. Please note that this strategy is extremely risky by nature and not suitable for beginners!
A single pound on Monday could get you 1.19 euros. On Tuesday, 1.20 euros. This tiny change may not seem like a big deal. But think of it on a bigger scale. A large international company may need to pay overseas employees. Imagine what that could do to the bottom line if, like in the example above, simply exchanging one currency for another costs you more depending on when you do it? These few pennies add up quickly. In both cases, you—as a traveler or a business owner—may want to hold your money until the forex exchange rate is more favorable.

There are two main types of retail FX brokers offering the opportunity for speculative currency trading: brokers and dealers or market makers. Brokers serve as an agent of the customer in the broader FX market, by seeking the best price in the market for a retail order and dealing on behalf of the retail customer. They charge a commission or "mark-up" in addition to the price obtained in the market. Dealers or market makers, by contrast, typically act as principals in the transaction versus the retail customer, and quote a price they are willing to deal at.
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.
Currencies are always traded in pairs, so the "value" of one of the currencies in that pair is relative to the value of the other. This determines how much of country A's currency country B can buy, and vice versa. Establishing this relationship (price) for the global markets is the main function of the foreign exchange market. This also greatly enhances liquidity in all other financial markets, which is key to overall stability.
Unlike stocks, forex trades have low, if any, commissions and fees. Even so, new forex traders are always advised to take a conservative approach and use orders, like stop-loss, to minimize losses. High leverage, which should be prudently applied, gives traders the opportunity to achieve dramatic results with far less capital than necessary for other markets. Forex trading requires training and strategy, but can be a profitable field for individuals looking for a lower risk endeavor. Learning currency trading gives traders a range of exciting new opportunities to invest in.
In return for executing your buy and sell orders, forex brokers will either take a commission per trade or a spread. A spread is the difference between the bid price and ask price for the trade. The asking price is the lowest price that a currency pair will be offered for sale and the bidding price is always lower. When forex brokers successfully execute a buy with the lower bid, they will take that difference — the spread — as payment.
In the futures market, futures contracts are bought and sold based upon a standard size and settlement date on public commodities markets, such as the Chicago Mercantile Exchange. In the U.S., the National Futures Association regulates the futures market. Futures contracts have specific details, including the number of units being traded, delivery and settlement dates, and minimum price increments that cannot be customized. The exchange acts as a counterpart to the trader, providing clearance and settlement.
