This isn't really trading, this is basically buying and selling business. If you buy apples and sell apples then you own a business, it is not trading at all. Trading is a lot quicker and it is not a product
By buying and selling apples, you don't create product and if you do it quickly, it's like trading, but trading apples. If you buy apples as a whole seller and distribute it by selling to other retail sellers, you have a business.
yeah trading is definitely more difficult, we're not selling things to buyer but selling it to another investor, who would like to take profit as well once the price increases. much similar with stocks.
With a trader, he does not care who will be a buyer of what he sells on the market. It's a free market where everyone can join as buyer or seller and except it's OTC market, you simply put your buying or selling order and wait for it to be filled with Limit order or sell it directly with Market price order.
therefore the price vary so much always changing dynamically every minute.
If you trade with too short candles like 1-minute, 5-minute, you will have very big risk. If you trade with such short candles and with leverage, it's more like suicide and you do it to lose money, not to get profit.
