you buy and sell currency based on the strategy that you have learned. It takes a long time to learn how to do it, you have to have a plan, and know how to study and analyse candlestick charts, read financial news, and have alot of time on your hands to do all this. my day is this: I know when each market around the world opens, I open up a monthly chart, weekly chart, daily chart, 4hour chart- then I draw strength and resistance lines, check the calender for any news about the pair I’m working on, then I check the 15 min chart, make a target, open the trade, and manage it with a 4hour, 15 minute chart, and a 1 minute chart. I do it with my own money, you have to be really really careful. Google stuff about it if you want to learn, don’t use robots, don’t pay to learn you can find all you want to know on the internet. It’s very time intensive, at least for me.
