What is Hedge? What is Arbitrage? What is Carry Trading? What is Martingale? What is Anti-Martingale? What is Grid? What is Day Trading? What is Scalping? What is Break-Out Trading? What is Pivot? What is News Trading? What is Trend Following? Nature Of Market: Every thing in the universe has its NATURE. So is Forex market. So is every currencies pair in this market. For example, GBP/JPY always moves faster, and its wave range is longer than other pairs, such as a hundred pips during a day or even a hour. EUR/GBP generally waves narrowly several pips only within a day. For American, EUR/USD and GBP/USD like to sleep in day and dance at night. AUD/USD and NZD/USD look like twin, they commonly act in the same style, if one of they goes north, another one does not like to go south. But EUR/USD and USD/CHF are doomed to be enemy, while one of them flies up like a hydrogen balloon, the counterpart mostly will drop like a lead ball. And so on, so on. Once we find this kind of "Nature of Market", we can develop and figure out some strategies for particular currency pairs, just follow their nature, predict their moving direction and range. Then we will get our own trading strategy and system.
