The trailing stop-loss is a dynamic procedure when the exit point moves closer to the entry point if the currency moves in the direction favorable to the trader. The trader may also do this as new support and resistance levels are formed as the currency moves in their direction.
The trailing stop decreases the risk if the currency initially moves in the trader's direction but then fails to follow through. The trailing stop also attempts to fix a minimum amount of profit if the rate moves substantially enough for the trader to move the trailing stop to a profitable level.

A requote in the forex world means that the broker you are dealing with is not able or willing to give you a trade based upon the price you entered. Generally this happens in a fast-moving market, usually around the time of a big news announcement or some kind of shock to the system. In essence, you decide to buy or sell a currency pair at a particular price and press the button to do so. By the time your broker gets the order, the market will have moved too fast to execute at the price advertised. In reality it is a difference between the price you decided to enter a trade by clicking buy/sell and the price on the market when your order actually reaches the broker.
