Interactive Market Course.
Traders (sellers and buyers) make transactions between themselves. Approximately 85% of them are speculative traders, who don’t need barrels of crude oil or three bags of wheat: they seek to profit from the rise and fall of the assets’ prices.
To open a trade, they use web platforms, like MetaTrader5. There are online charts of the real-time price changing, as well as Buy and Sell buttons.
When traders see the price has started to grow, they click on “Buy”, waiting for further increase. As soon as they understand that the price is turning down, they click “Close” to finish the trade. If their forecast was correct, they will have a profit.
