The mere expectation or rumor of a central bank foreign exchange intervention might be enough to stabilize the currency. However, aggressive intervention might be used several times each year in countries with a dirty float currency regime. Central banks do not always achieve their objectives. The combined resources of the market can easily overwhelm any central bank. Several scenarios of this nature were seen in the 1992–93 European Exchange Rate Mechanism collapse, and in more recent times in Asia.
Risk/reward signifies how much capital is being risked to attain a certain profit. If a trader loses 10 pips on losing trades but makes 15 on winning trades, she is making more on the winners than she's losing on losers. This means that even if the trader only wins 50% of her trades, she will be profitable. Therefore, making more on winning trades is also a strategic component for which many forex day traders strive.
Forex alerts or signals are delivered in an assortment of ways. User generated alerts can be created to ‘pop up’ via simple broker trading platform tools, or more complex 3rd party signal providers can send traders alerts via SMS, email or direct messages. Whatever the mechanism the aim is the same, to trigger trades as soon as certain criteria are met.
The practice of taking on excessive risk does not equal excessive returns. Almost all traders who risk large amounts of capital on single trades will eventually lose in the long run. A common rule is that a trader should risk (in terms of the difference between entry and stop price) no more than 1% of capital on any single trade. Professional traders will often risk far less than 1% of capital.
Forex is a portmanteau of foreign currency and exchange. Foreign exchange is the process of changing one currency into another currency for a variety of reasons, usually for commerce, trading, or tourism. According to a recent triennial report from the Bank for International Settlements (a global bank for national central banks), the average was more than $5.1 trillion in daily forex trading volume.
