I don’t think it is a good idea for newbies to use leverage because leverage is a tool that has both positive and negative effects. If used properly, leverage can magnify profits but if the market goes in the other direction, then it can magnify losses as well. Since newbies lack trading experience, using leverage will drag them towards ‘magnified losses’. If they want to use leverage, then it should be on the lower side to avoid heavy losses in case of an unfavorable trade.
