Forex (foreign exchange) is the global market for exchanging one currency for another. It is the largest financial market in the world by trading volume, running nearly around the clock as different financial centres — Sydney, Tokyo, London, New York — hand the market to one another through the day. In UHX Trader you practise this with a virtual balance — there is no real money involved.
How currency pairs are quoted
Currencies are always traded in pairs, because you are exchanging one for another. Take EUR/USD: the first currency (EUR) is the base currency, and the second (USD) is the quote currency. A price of 1.0950 means one euro buys 1.0950 US dollars. When that number rises, the euro has strengthened against the dollar; when it falls, the euro has weakened. Learning to read that relationship is the foundation for everything else in the simulator.
Why prices move
Currency prices move constantly because they reflect the combined view of everyone trading that pair at that moment. A few of the biggest drivers are:
- Economic data — inflation, employment and growth figures shift expectations about a country's economy.
- Central bank decisions — interest rate changes are one of the strongest forces on a currency's value.
- Market sentiment — during uncertain periods, traders often favour currencies seen as safer, such as the US dollar, the Japanese yen, or the Swiss franc.
- Session overlaps — when two major sessions are open at once, such as London and New York, activity and price movement tend to pick up.
This is not investment advice — it is simply what tends to influence a pair's price, and it is exactly the kind of context that makes a chart easier to read.
Practise this
Open the simulator, pick EUR/USD or GBP/USD, and watch the price for a few minutes. Notice how it never stands still — small, continuous moves are normal, and getting used to that rhythm with a virtual balance is a safe first step before you look at any other pair.
