Some of these factors include political stability, interest rates, inflation, terms of trade, public debt and current account deficits. For example, in the case of interest rates, if rates are higher, lenders get a better return compared to those in a country with lower rates; therefore the higher rates attract foreign capital which causes the exchange rate to rise. This is one of the reasons forex traders may look to trade on interest rate announcements from central banks like the US Federal Reserve or the Bank of England.  
For this strategy, we will use the Exponential Moving Average (EMA) indicator. The previous week's last daily candlestick has to be closed at a level above the EMA value. Now we have to look for the moment when the previous week's maximum level was broken. Next, a buy stop order is placed on the H4 closed candlestick, at the price level of the broken level.
