It has to do with a personal online free trade, where the 'trader' (the person that is involved in the trading) will make transactions on an online platform of a chosen site (there are many of the same sites of various companies); the trader, in this case, works on a personal and individual level - that is why it is called 'Arbitrage Trading' (=Free Trade), investing a sum of money in his/her own account, with which he/she will make the transaction. This means, that the amount will be invested in buying and selling items of other companies available online, according to the daily price of the item of each product, in order to earn money from his/her invested funds.

Today, online trading is open to endless possibilities: we can buy the classic shares from the stock market, buy cryptocoins, or even regular currencies like USD or EUR. The latter is one of the most popular way of doing trading nowadays, i.e. the trader can sell or buy amounts of currencies according to the exchange rate bourse at a given time; for example, transactions are made between EUR/USD by clicking on the 'green' currency each time it shows which currency is winning at the moment, avoiding to click on the 'red' currency line which shows a loss.
While this sound extremely easy to do, that is not really the case: the value of the currencies is constantly changing, so one has to be extremely quick and careful in order to not lose his money.
In a matter of seconds, or even less than a second, the ratio between two currencies can change, so what could’ve been a profitable exchange 2 seconds ago can now be a transaction that we must avoid to protect our investment.
To make our arbitrage journey easier, and safer, there is plenty of online software that can help us in exchanging currencies between online platforms.
Those exchange software not only keep track of the value of the currencies on different platforms, but also allow us to buy/sell the currencies automatically, and in a way that is surely faster, and safer, than doing it manually.
We must explain at this point that the merchant will withdraw his already invested funds online, or invest part of his money in transactions, to be able to lose less, to save without 'high risk', and finally earn more. Of course, there are general rules to follow in trading, in relation to other traders who do the same online at the same time and to be patient and honest with their work. Thus, everyone can be protected from the risk of losing (their) money, everything being above all a matter of experience: Investing a little, earning more, one day, depending on the state of the daily stock market, and above all on the global economic/financial situation. You cannot know until you try... The Arbitrage Trading described here is also that everyone works alone, free, and always determines his own working time. -It is possible to switch it off at any time.
