One approach I adopted as a newbie is to stay away from trading at all means because i already know that the risk in trading is equivalent to the risk in gambling, and most of those that ever make profits from trading also recorded alot of loses that could possibly outweigh the profits amount.
If all the newbies stay away from trading, then we will no longer be able to see traders in the future, so instead of giving advice to these newbies to stop dealing with trading, it is better for us to be able to give them a few tips and tricks so that they understand more about trading. It is true that trading is quite risky because one can lose their money, but everything in this world has risks, and it is our choice whether to take that risk or not. So there's no harm in getting involved in trading, but of course it all requires preparation, a newbie can learn what instruments they want to choose, what is the best strategy, how to stop-loss, determine entry-exit, etc. - if this is done I think that their potential losses in trading will be minimized.
