Forex is always traded in pairs – for example AUD/USD. You speculate on whether the price of one country's currency will rise or fall against the currency of another country, and take a position accordingly. Looking at the AUD/USD currency pair, the first currency (AUD) is called the 'base currency' and the second currency (USD) is known as the 'counter currency'. 
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.
