In the above hourly price chart, it is clear to see there has been multiple interactions with the 21 EMA. Sometimes price has bounced off the moving average and sometimes it has broken through. As it has bounced off more times than it has broken through this 'setup' can serve as the basis of this strategy. So now let's identify some rules around this.

The theory follows sequences of five waves, or five up and down price movements which are then countered by a corrective 3 wave pattern in the opposite direction. The 5 impulsive waves are with the trend, whereas the 3 corrective waves are counter trend. In an 'up' move, there will be three up waves (movements 1, 3 and 5) and two down waves (movements 2 and 4).
Balance of trade levels and trends: The trade flow between countries illustrates the demand for goods and services, which in turn indicates demand for a country's currency to conduct trade. Surpluses and deficits in trade of goods and services reflect the competitiveness of a nation's economy. For example, trade deficits may have a negative impact on a nation's currency.
Decide how you will finance your trading in advance: Only one kind of money is good for investing, and that's the kind that you are willing to lose, and preferably without damaging your physical and/or mental wellbeing in the process. Every profitable trader is profitable in their own way, while every loser experiences losses exactly the same way. Remember, use every available opportunity to learn. It's a never-ending process!
More specifically, the spot market is where currencies are bought and sold according to the current price. That price, determined by supply and demand, is a reflection of many things, including current interest rates, economic performance, sentiment towards ongoing political situations (both locally and internationally), as well as the perception of the future performance of one currency against another. When a deal is finalized, this is known as a "spot deal". It is a bilateral transaction by which one party delivers an agreed-upon currency amount to the counter party and receives a specified amount of another currency at the agreed-upon exchange rate value. After a position is closed, the settlement is in cash. Although the spot market is commonly known as one that deals with transactions in the present (rather than the future), these trades actually take two days for settlement.
The foreign exchange market – also called forex, FX, or currency market – was one of the original financial markets formed to bring structure to the burgeoning global economy. In terms of trading volume it is, by far, the largest financial market in the world. Aside from providing a venue for the buying, selling, exchanging and speculation of currencies, the forex market also enables currency conversion for international trade settlements and investments. According to the Bank for International Settlements (BIS), which is owned by central banks, trading in foreign exchange markets averaged $5.1 trillion per day in April 2016.
Governments / Central banks – A country’s central bank can play an important role in the foreign exchange markets. They can cause an increase or decrease in the value of their nation’s currency by trying to control money supply, inflation, and (or) interest rates. They can use their substantial foreign exchange reserves to try and stabilize the market.

In the U.S., the National Futures Association regulates the futures market. Futures contracts have specific details, including the number of units being traded, delivery and settlement dates, and minimum price increments that cannot be customized. The exchange acts as a counterpart to the trader, providing clearance and settlement.
