You can never reduce the risk to 0% obviously but you can reduce it by learning TA (technical analysis) and FA (fundamental analysis). Technical analysis is the study of charts and patterns in said charts, fundamental analysis is being smart about what's going on (if some news will affect the price or not).
These are all the tools we have, unless you have insider information of course. I don't think it's viable as a job, most people lose money. Just wait for big dips, buy them and hold it.
Any sites you can share teaching the basic technical analysis and giving an advice for fundamental analysis?
Thank you.
I think there's no sites on it or if they do, they were asking for a price before you know it because doing it, you must learn it through to yourself. Experience will going to teach you all of those TA and FA and with the help of your friend who or anyone who do tradings too. If you can pay for that price i think you can find it anywhere here, but you have to ask them first.
