How currencies are traded in Forex?

How currencies are traded in Forex?

In our opening lesson “What’s Forex and how it works” I provided a brief account of main participants of currency market and what make exchange rates fluctuate. It is essential information you need to know, but not sufficient to start trading. Let’s examine exact process of how currencies are exchanged, what are costs of these transactions and how to profit from them.

First thing you need to know is that currencies are traded in PAIRS. Not in triads, quartets etc. Symbols like EUR/USD or USD/JPY mean two currencies that “compete” against each other – EUR/USD is EURO vs US Dollar, USD/JPY is US Dollar vs Japanese Yen. When you see a message that EUR/USD fell by 1% it means that EUR value decreased against USD by 1% or USD appreciated against EUR by 1%. It can sound a bit confusing so lets put it simple, considering on the of currencies as a “good”:

A currency that comes before “/” is called “base currency” (good), currency that comes after “/” is called “quote currency” (money you pay for the good) and the number in right side is “exchange rate”. In our case EUR/USD=1.10 means that if we buy 1 EUR we pay 1.10 Dollars, if we sell 1 EUR we get 1.10 Dollars.

Consider other examples:

USD/JPY = 118.20 –  to buy 1 Dollar we pay 118.20 Japanese Yens, if we sell 1 Dollar we get 118.20 Yens.

EUR/GBP= 0.77  to buy 1 Euro we pay 0.77 pounds.

So what “EUR/USD rose from 1.10 to 1.12” exactly mean? It means that to buy 1 Euro we now need more Dollars (1.12 USD instead 1.10 USD). In other words we need to spend more Dollars to buy Euros or Euro became more expensive that USD.

When exchange rate rise = base currency become more expensive or quote currency become cheaper.

When exchange rate drops = base currency become cheaper or quote currency become more expensive.

Hope its clear. Moving further.

Now we understand which exact changes mean fluctuations in exchange rate. So if we expect that exchange rate of EUR/USD will rise how to profit from it?

The answer is – we should buy EUR/USD. When we make such transaction it means that we buy EUR and pay with USD for it. And vice versa, when we sell EUR/USD it means that we sell EUR and get USD instead.

Here are simplified calculations of what happens when you try to speculate on currencies:

For example you think that exchange rate of EUR/USD will rise from 1.10 to 1.20. You buy 100 000 EUR paying 110 000 USD for it. Then exchange rate rises from 1.10 to 1.20 and you execute reverse transaction: Sell your 100 000 EUR and get 120 000 USD instead. Net profit is 10 000 USD.

But what happens if exchange rate falls short of your expectations and drop from 1.10 to 1.00? You buy 100 000 EUR for 110 000 USD but when making reverse transaction when exchange rate dropped to 1.00 you get back only 100 000 USD. Net loss is 10 000 USD.

Here we have important conclusion: Any trade consists of two transactions, where second transaction is reverse to first.

We already know such currency pairs like EUR/USD, USD/JPY, AUD/USD. But how much pairs there are and what pairs are best to trade? Let me try to answer this questions.

Trading is possible providing that there is a counterparty willing to sell you what you want to buy and buy what you want to sell, i.e. make an exchange with you. When you want to sell EUR/USD there should be a counterparty willing to buy EUR/USD in the same amount. Same for reverse transaction. It is quite logical that the more members willing to exchange the better for every member as they can complete exchanges faster. Its called Liquidity. The bigger is Supply and Demand the better is liquidity. Did you guess which currency pair is most liquid? Of course it is EUR/USD. It means that if you decide to buy 10 000 000 EUR for USD at current exchange rate I’m pretty sure you can do that almost Instantly. But if you try to exchange 10 Million Dollars for example to Mexican Pesos it should take some more time because there’s less Supply of Pesos and probably less demand for such amount of Dollars (less number of market participants). In this case, it is said market has thin liquidity.

Returning to our main question which pairs are popular in forex and why are they and not some other:

The answer is: most popular pairs are those with best liquidity. They’re split into groups:

Majors:

EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD, USD/CAD. Why are they? Because United States, European Union, Japan, Switzerland, Canada, Australia are biggest economies in the world thus has biggest Supply and Demand on their national currencies on foreign exchange market.

Next are cross pairs:

EUR/CHF, EUR/JPY, NZD/JPY, EUR/GBP, CAD/JPY. These are just some of them. Why are they called cross pairs? Because these are major currencies but not quoted in Dollar. They are less liquid than majors but enough to trade with large positions (200 000, 500 000 currency units or even more).

And last are minor pairs or so called exotics:

USD/RUB, USD/TRY, USD/NOK, USD/MXN, USD/ZAR, USD/SGD. Most of them has USD as second currency because only with USD they have adequate liquidity to make trading possible.

Okay, now we know that there are three types of currency pairs and they all have different liquidity. But what pair to choose for trading?

Actually the question is incorrect :). Quick glance may suggest that best pair to choose is EUR/USD or other majors. But its not absolutely true. For example USD/MXN may be more preferable for you because you’re living in Mexico and know your national currency – Mexican Peso (MXN) better than international traders. You can get quicker access to local news, events, government decision that may affect currency and thus USD/MXN exchange rate and turn it into your favor. In trading terminology its called “EDGE”. Having an edge means know something that other traders may don’t know and what you can use to predict the moves of certain currency. Trading knowledge, access to information and quick response are three main constituents of consistent profitable trading.

In next lesson we will study what are transactions costs – Spreads and commissions and how they connected to liquidity of a pair. We will also find out what are other expenses you can incur during your trading.
