Currency Trading
Terms
Spot Forex or
FX Market
A Spot forex market is a market for immediate transactions
as opposed to an agreement to make a transaction some time in the
future (eg. futures).It is often referred to as the "interbank"
market. A spot foreign exchange transaction is a contract to exchange
two currencies, typically in two business days), at an exchange
rate agreed today. Spot Forex allows the trader high liquidity,
strong profit potential from continual market fluctuations by buying
a specific currency when it is weaker and selling it when it is
stronger, and the continual pairing of strong currencies against
weak ones. All the futures trading offered in RapidSP use the SPOT
Forex data.
Prices
The price of a currency (foreign exchange rate) is always given
in terms of another currency. That is why you will hear that currencies
trade in "pairs." In the Interbank market, the currency
pairs are standardized; for example, euros in terms of dollars,
dollars in terms of Japanese Yen, and not the other way around.
An example can make this clearer. Let's say that the price of the
euro versus the dollar is:
EUR/USD = 1.2125
This means that 1-euro is equal to 1.2125 US Dollars. The currency
to the left of the forward slash ("/") is called the "base
currency" and the one on the right is called the "quote
currency" (also called the "counter currency"). Currency
quotes are thus given for the base currency in terms of the quote
currency; i.e., euros in terms of dollars - 1 euro is equal to 1.2125
dollars. Day traders new to currencies might be confused trying
to interpret the quote above mathematically; in other words, thinking
that EUR/USD means euros per dollar (it does not - it actually means
dollars per euro!!!). This is a mistake that is quickly avoided
when you simply memorize to add a one (1) in front of the EUR/USD
and understand that the number on the right (1.2125), beside the
second currency, is the number of units of the second currency;
in other words, the quote EUR/USD = 1.2125 means that 1 EUR is equal
to 1.2125 USD.
There are a few exceptions
to prices with four decimal places; for example, the quote of the
dollar versus the yen is taken only to two decimal places. Let's
see what this means?
USD/JPY = 107.65
This means that (reading from left to right) 1 USD is equal to 107.65
JPY (Japanese Yen).
Pips
When day trading currencies, the term PIP is used often. A pip,
which stands for "price interest point," represents the
smallest fluctuation in the price of a currency. This is similar
to the concept of "tick" for stocks. So how much is a
pip worth? The value of a pip depends on the size of the contract
(or lot) that is traded. Most online forex brokers offer regular
contracts (or lot) sizes of 100,000 units of the base currency.
With this figure in mind, we could determine what a pip is worth.
Let's take the quote example above of EUR/USD = 1.2125. If:
1 euro equals 1.2125 dollars, then 1 lot (or contract) of 100,000
euros should be worth 121,250 dollars and a fluctuation of 0.0001
(1 pip) should be worth 100,000 x 0.0001 = 10 dollars. Therefore,
every time the price of the euro versus the dollar fluctuates by
one pip, the value of each contract changes by 10 dollars. For currencies
that are quoted in terms of dollars (that is, when the USD is the
quote currency), the PIP value is fixed (10 dollars if the currency
is quoted to the fourth decimal place). This is what is called a
"static pip value" because the value is constant relative
to the dollar. Major currencies (other than the EUR/USD) with a
static pip values are the GPB/USD (British Pound versus the US Dollar
- also known as "cable") and the AUD/USD (Australian Dollar
versus the US Dollar - also know as "aussie").
Are there currencies with a "variable pip value?" Yes
there are. A currency with a variable pip value is one that has
the dollar as the base currency. The major currencies or "majors"
with a variable pip value are the USD/JPY, the USD/CHF (US Dollar
versus the Swiss Franc), and the USD/CAD (US Dollar versus the Canadian
Dollar). Using the earlier example of the USD/JPY = 107.65, if:
1 USD equals 107.65 yen, then 1 lot of 100,000 dollars should be
worth 10,765,000 yen and one pip should be worth 100,000 x 0.01
= 1000 yen. If we want to turn this value into dollars, we have
to divide by the current exchange rate (107.65 yen per dollar).
Thus, 1000 / 107.65 = 9.29 dollars. We automatically conclude that
the value of one pip in the dollar-yen currency pair (in terms of
dollars) will always vary as the exchange rate varies.
Since currencies are traded in lots (or contracts) and each standard
lot is worth 100,000 units of the base currency, In currency trading,
the margin requirement can be anywhere from 1,000 (1%) to 2,000
(2%) units of the base currency per lot depending on the broker.
This represents a leverage of 50 to 1 to 100 to 1. HUGE!!! This
is one of the advantages currencies have over stocks for day trading
purposes. Even though a 50 to 1 margin is excessive for most trading
styles, it is available to the trader nevertheless. The trader is
free to decide what amount of leverage to use depending on the nature
of the day trading strategy that he is using, his available trading
capital, and the risk he is willing to take on each transaction.
Mini forex accounts, also known as forex minis, can be used by day
traders who do not have sufficient capital to trade regular accounts
with contract sizes of 100,000 or more. Mini accounts typically
offer contract sizes of 10,000 instead of 100,000 and margin requirements
per contract of $50 or more (instead of the $1,000 to $2,000 per
contract required in regular accounts). Consequently, mini forex
trading accounts have account minimums that are much lower than
that of regular accounts (as low as a few hundred dollars or less
in some cases!). This allows small investors to day trade currencies
using the same platform as regular forex traders. Some currency
brokers offer a wider spread for mini accounts and some might charge
a transaction per trade. In reality, if the mini contract is 10,000
units of the base currency, then all of the calculations are simply
a tenth of what they would be for regular accounts with 100,000
lot sizes; for example, the value of 1 pip for the EUR/USD on a
mini contract will be 1 dollar instead of 10.
Bid and Ask
For currencies, like for stocks, there is not just one price to
worry about. A quote is given as a bid price and and ask price.
So if we are using an online day trading platform, we might see
the following for the EUR/USD currency pair:
EUR/USD
Bid 1.2105 Ask 1.2109
This means that an institution
(let's say a bank) is trying to buy (Bid) the euro versus the dollar
at 1.2105 and another institution is offering to sell euros versus
the dollar (Ask) at 1.2109. As currency day traders, we can buy
from the bank that is selling at 1.2109 or sell to the bank that
is buying at 1.2105. (In general, systems that allow a trader to
post bid and ask prices for currencies do not have enough liquidity
at the moment, so traders have to buy at the ask and sell at the
bid.
Margin requirements
The margin (amount of money you need to deposit with your
broker to trade a particular contract) requirement varies from broker
to broker. Typically it is about 1/100th of the lot size. For example
to trade one standard contract of EURUSD you will need to deposit
about $1200 with your broker.
