Key Concepts Behind a Retail Forex Trade
Currency Pairs
Currency prices can only fluctuate relative to another currency, so they are traded in pairs. Take two of the most common currency pairs, the EURUSD (the price for euros in US dollars) and the GBPUSD (the price for the British pound in US dollars).
High Leverage
The idea of margin (leverage) and floating loss is another important trading concept and is perhaps best understood using an example. Most retail Forex market makers permit 100:1 leverage, but also, crucially, require you to have a certain amount of money in your account to protect against a critical loss point. For example, if a $100,000 position is held in EURUSD on 100:1 leverage, the trader has to put up $1,000 to control the position. However, in the event of a declining value of your positions, Forex market makers, mindful of the fast nature of forex price swings and the amplifying effect of leverage, typically do not allow their traders to go negative and make up the difference at a later date. In order to make sure the trader does not lose more money than is held in the account, forex market makers typically employ automatic systems to close out positions when clients run out of margin (the amount of money in their account not tied to a position). If the trader has $2,000 in his account, and he is buying a $100,000 lot of EURUSD, he has $1,000 of his $2,000 tied up in margin, with $1,000 left to allow his position to fluctuate downward without being closed out.
Typically a trader's trading platform will show him three important numbers associated with his account: his balance, his equity, and his margin remaining. If trader X has two positions: $100,000 long (buy) in EURUSD, and $100,000 short (sell) in GBPUSD, and he has $10,000 in his account, his positions would look as follows: Because of the 100:1 leverage, it took him $1,000 to control each position. This means that he has used up $2,000 in his margin, out of a $10,000 account, and thus he has $8,000 of margin still available. With this margin, he can either take more positions or keep the margin relatively high to allow his current positions to be maintained in the event of downturns. If the client chooses to open a new position of $100,000, this will again take another $1,000 of his margin, leaving $7,000. He will have used up $3,000 in margin among the three positions. The other way margin will decrease is if the positions he currently has open lose money. If his 3 positions of $100,000 decrease by $5,000 in value (which is fairly common), he now has, of his original $7,000 in margin, only $2,000 left.
If you have a $10,000 account and only open one $100,000 position, this has committed only $1,000 of your money plus you must maintain $1,000 in margin. While this leaves $9,000 free in your account, it is possible to lose almost all of it if the speculation loses money.
Transaction Costs and Market Makers Market makers are well compensated for allowing retail clients to enter the forex market. They take part or all of the spread in all currency pairs traded. In a common example, EURUSD, the spread is typically 3 pips (3/100 of a percent). Thus prices are quoted with both bid and offer prices (e.g., Buy EURUSD 1.2000, Sell EURUSD 1.2003). That difference of 3 pips is the spread and can amount to a significant amount of money. Because the typical standard lot is 100,000 units of the base currency, those 3 pips on EURUSD translate to $30 paid by the client to the market maker. However, a pip is not always $10. A pip is 1/100th of a percent, and the currency pairs are always purchased by buying 100,000 of the quote currency, which is also known as the counter currency. For the pair EURUSD, the base currency is USD; thus, 1/100th of a percent on a pair with USD as the base currency will always have a pip of $10. If, on the other hand, your currency has Swiss Franc (CHF) as a base instead of USD, then 1/100th of a percent is now worth around $8, because you are buying 100,000 worth of Swiss Francs.
Financial Instruments
There are several types of financial instruments commonly used.
Forwards
One way to deal with the Forex risk is to engage in a forward transaction. In this transaction, money does not actually change hands until some agreed upon future date. A buyer and seller agree on an exchange rate for any date in the future, and the transaction occurs on that date, regardless of what the market rates are then. The duration of the trade can be a few days, months or years.
Futures
Foreign currency futures are forward transactions with standard contract sizes and maturity dates — for example, 500,000 British pounds for next November at an agreed rate. Futures are standardized and are usually traded on an exchange created for this purpose. The average contract length is roughly 3 months. Futures contracts are usually inclusive of any interest amounts.
Swaps
The most common type of forward transaction is the currency swap. In a swap, two parties exchange currencies for a certain length of time and agree to reverse the transaction at a later date. These are not contracts and are not traded through an exchange. Spot A spot transaction is a two-day delivery transaction, as opposed to the futures contracts, which are usually three months. This trade represents a “direct exchange” between two currencies, has the shortest time frame, involves cash rather than a contract; and interest is not included in the agreed-upon transaction. The data for this study come from the Spot market.
