Traders who understand indicators such as Bollinger bands or MACD will be more than capable of setting up their own alerts. But for the time poor, a paid service might prove fruitful. You would of course, need enough time to actually place the trades, and you need to be confident in the supplier. It is unlikely that someone with a profitable signal strategy is willing to share it cheaply (or at all). Beware of any promises that seem too good to be true.
Imagine a trader who expects interest rates to rise in the U.S. compared to Australia while the exchange rate between the two currencies (AUD/USD) is 0.71 (it takes $0.71 USD to buy $1.00 AUD). The trader believes higher interest rates in the U.S. will increase demand for USD, and therefore the AUD/USD exchange rate will fall because it will require fewer, stronger USD to buy an AUD.
Answer: When trading most traders think only about the trading strategy entry and entirely forget about the exit. The truth is that closing your trade is one of the most critical parts of your trading strategy. This is because if you can't exit the trade with the profit, you won't be a winning trader. Make sure you develop a plan that will help you get out of trades quickly and do not just focus on how to get into the trades.
Trading forex can be an ultimately rewarding experience, but you must learn the ins and outs first. There is a lot of risk involved and this most definitely outweighs the returns for those who jump the gun and start trading without being fully prepared. Take the time to work on your education - it’s the most important aspect of forex trading. Knowledge is power, and that power will enable you to make logical decisions and continue trading long past the time when a lot of players have gone bust.
