All forex trades involve two currencies because you're betting on the value of a currency against another. Think of EUR/USD, the most-traded currency pair in the world. EUR, the first currency in the pair, is the base, and USD, the second, is the counter. When you see a price quoted on your platform, that price is how much one euro is worth in US dollars. You always see two prices because one is the buy price and one is the sell. The difference between the two is the spread. When you click buy or sell, you are buying or selling the first currency in the pair.
While a margin amount of only 1/50th of the actual trade size is required from the trader to open this trade, however, any profit or loss on the trade would correspond to the full $100,000 leveraged amount. In the case of USD/CAD at the current market price, this would be a profit or loss of around $10 per one-pip move in price. This illustrates the magnification of profit and loss when trading positions are leveraged with the use of margin.
In contrast, when a trader opens a position that is expected to last for a few minutes or even seconds, they are mainly aiming to extract the maximum amount of profit within a limited time. What is the best forex leveraging in this case? Usually such a person would be aiming to employ high, or in some cases, the highest possible leverage to assure the largest profit is realised, while trading small market fluctuations.
When scalping, traders tend to employ a leverage that starts at 50:1 and may go as high as 500:1. Knowing the effect of leveraging and the optimal leverage Forex trading ratio is vital for a successful trading strategy, as you never want to overtrade, but you always want to be able to squeeze the maximum out of potentially profitable trades. Usually a trader is advised to experiment with leverage within their strategy for a while, in order to find the most suitable one.

Finally, it is important to note that in leveraged forex trading, margin privileges are extended to traders in good faith as a way to facilitate more efficient trading of currencies. As such, it is essential that traders maintain at least the minimum margin requirements for all open positions at all times in order to avoid any unexpected liquidation of trading positions.
Forex trading involves the sale of a currency, and the simultaneous purchase of another with the purpose of closing the position at a later time with a profit. Unlike in the stock or commodities markets where prices are routinely quoted in USD, the price of a currency can be quoted in any other currency due to the essentially bartering nature of currency transactions where live, as well as historical, forex charts are used to identify trends and entry/exit points for trades.

Currencies are traded on the Foreign Exchange market, also known as Forex. This is a decentralized market that spans the globe and is considered the largest by trading volume and the most liquid worldwide. Exchange rates fluctuate continuously due to the ever changing market forces of supply and demand. Forex traders buy a currency pair if they think the exchange rate will rise and sell it if they think the opposite will happen. The Forex market remains open around the world for 24 hours a day with the exception of weekends.
