In the stock market, traders profit from the magnitude and frequency of fluctuations, most commonly known as volatility. Currency traders make profits due to the large volume of transactions in this market coupled with the small number of trading instruments and high liquidity. The profitability opportunities are such that a currency trader can effectively earn five times more from trading forex than any other liquid shares.
The measure of volatility for most stocks is between 50 and 100. This is the measure of the expected maximum return generated by a trader. Currency trading volatility is 500. This makes forex a more suitable option for day trading.
Usually, in order to trade shares you are required to put up all the funds independently, since most banks will not lend for this purpose. However, the trading of currency relies on ‘borrowed money’, therefore you can invest a nominal sum, for example between $50 and $200, into your trader account and yet you can trade $10,000 of currency with lending ratios of 200:1 and 50:1 respectively.
Again, to draw comparison with the stock market, you can only make profit when the value of the stock rises. When the value is plummeting the only option is to sell those stocks. However, in the currency market, you can still trade a currency downward when you believe it is going to lose value. You can also still make profit this way, because you are buying one currency and selling another simultaneously.
