Why People Trade Currencies

Transactions and hedging

An importer buying euros to pay a supplier is transacting; the exchange rate is a cost, not an opportunity. An airline that knows it will buy fuel in dollars next quarter and locks in today's rate is hedging: it gives up the chance of a better rate to remove the risk of a worse one. Both are rational without any view on where the currency is going.

Speculation

A speculator has no underlying need for the currency. They buy EUR/USD because they expect the price to rise and intend to sell it back later. Their profit is the difference between the two prices, less the costs of trading. That is the whole business: forming a view, sizing a position so a wrong view does not do lasting damage, and getting in and out at a cost low enough to leave something over.

What attracts retail traders

• The market is open 24 hours on weekdays, so it fits around a job.
• It costs very little to start; many brokers open accounts from a few dollars.
• Leverage allows a small deposit to control a large position.
• The major pairs are liquid, so orders fill quickly and spreads are tight.
• You can profit from a falling currency as easily as a rising one, because every trade is a pair.

The trade-offs

Each of those attractions has a cost. Round-the-clock trading invites overtrading. Low minimum deposits mean under-capitalised accounts. Leverage magnifies losses exactly as it magnifies gains, and it is the reason most new accounts do not survive their first year. Liquidity in the majors does not extend to exotics, and being able to short means being able to be wrong in both directions. None of this is a reason not to trade; it is the reason the course on leverage and risk exists.

Key takeaways

• Most forex activity is commercial or hedging; retail trading is speculation.
• A speculator profits from the difference between entry and exit prices, less costs.
• Forex attracts retail traders with access, low minimums, leverage and liquidity, each of which cuts both ways.
