Currency speculation is considered a highly suspect activity in many countries.[where?] While investment in traditional financial instruments like bonds or stocks often is considered to contribute positively to economic growth by providing capital, currency speculation does not; according to this view, it is simply gambling that often interferes with economic policy. For example, in 1992, currency speculation forced Sweden's central bank, the Riksbank, to raise interest rates for a few days to 500% per annum, and later to devalue the krona.[82] Mahathir Mohamad, one of the former Prime Ministers of Malaysia, is one well-known proponent of this view. He blamed the devaluation of the Malaysian ringgit in 1997 on George Soros and other speculators.

Trading currencies is the act of making predictions based on minuscule variations in the global economy and buying and selling accordingly. The exchange rate between two currencies is the rate at which one currency will be exchanged for another. Forex traders use available data to analyze currencies and countries like you would companies, thereby using economic forecasts to gain an idea of the currency's true value.

The Forex martingale strategy: The martingale strategy is a trading strategy whereby, for every losing trade, you double the investment made in future trades in order to recover your losses, as soon as you make a successful trade. For instance, if you invest 1 EUR on your first trade and lose, on the next trade you would invest 2 EUR, then 4 EUR , then 8 EUR and so on. Please note that this strategy is extremely risky by nature and not suitable for beginners!

When trading Forex, you'll see that both 'Bid' and 'Ask' prices are quoted. The bid price is the price at which you can buy the currency, while the ask price is the price at which you can sell it. If you are purchasing a currency in a trade, this is known as a long trade, and the hope is that the currency pair will increase in value, so that you can sell it at a higher price and make a profit on the difference.
Many new traders choose not to close a trade because the market is still moving in the direction they want it to, only to then lose all of their gains when the direction suddenly changes. If your trade hits your predetermined target, close it and enjoy your winnings. If the market moves in the opposite direction, close the trade or set a stop loss so it will close automatically.
The foreign exchange market is where currencies are traded. Currencies are important to most people around the world, whether they realize it or not, because currencies need to be exchanged in order to conduct foreign trade and business. If you are living in the U.S. and want to buy cheese from France, either you or the company that you buy the cheese from has to pay the French for the cheese in euros (EUR). This means that the U.S. importer would have to exchange the equivalent value of U.S. dollars (USD) into euros. The same goes for traveling. A French tourist in Egypt can't pay in euros to see the pyramids because it's not the locally accepted currency. As such, the tourist has to exchange the euros for the local currency, in this case the Egyptian pound, at the current exchange rate.
