You can get to use a reliable brokerage after reading reviews like IG Review to involve in a forex trade. However, the following are the reasons to do so.

High liquidity
Among all the trading markets out there, forex trading is of high liquidity. It will be easy to buy or sell an asset without any variations in its value. If a financial market is highly active, it would be highly liquid simultaneously. Hence, the forex market that lets you trade 24×7 will have high liquidity. Although there would be little variance involved in the exchange, you can achieve greater profitability by understanding better trading strategies. Your risk will be minimal in forex trading.
Possibility for high profits
Forex trading is highly volatile. As the currency values could change due to several internal and external factors of the country’s economy, you could make a lot of money if you use the opportunities in the right way. For instance, the currency value of a particular country would change when the economy goes unstable. Also, a natural disaster could make the value dip. Likewise, if a country is seeming to lose its currency’s value, you can predict the downfall and bet on the lower values.
Directional trading
You would have heard the terms long and short in trading markets. They are nothing but your position with your prediction in the market. For instance, let us assume that you predict that a currency value is going to rise in the future against another currency. So, you can go for the long option by buying the currency pair. If the prediction goes right, you can get the profit. Similarly, you can go short for a negative prediction by selling the currency pair at the current price.
