Like most technical strategies, identifying the trend is step 1. Many scalpers use indicators such as the moving average to verify the trend. Using these key levels of the trend on longer time frames allows the trader to see the bigger picture. These levels will create support and resistance bands. Scalping within this band can then be attempted on smaller time frames using oscillators such as the RSI. Stops are placed a few pips away to avoid large movements against the trade. The MACD indicator is another useful tool that can be exercised by the trader to enter/exit trades.
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'. 
There is an additional rule for trading when the market state is more favourable to the system. This rule is designed to filter out breakouts that go against the long-term trend. In short, you look at the 25-day moving average (MA) and the 300-day moving average. The direction of the shorter moving average determines the direction that is permitted. This rule states that you can only go:
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.
