First of all, we need to know what arbitrage trading is all about. If you had to define arbitrage trading then it goes like this; A kind of hedged investment meant to capture slight differences in price; when there is a difference in the price of something on two different markets the arbitrageur simultaneously buys at the lower price and sells at the higher price. Like all forms of trading, this is profitable as well. Here trading is done when the opportunity presents itself and cannot be done all the time. This form of trading can be done only during the day when the markets are active. To be able to make large profits using this method, you need arbitrage training.
