Experience and learning are required but they are not so much learned as acquired. Theory alone or hunches alone will most likely cause the new trader to lose consistently and possibly fatally for your grub stake. Narrow your focus to things you know the most about. A farm boy might concentrate on food companies or farm implement manufacturers or on grain handlers for example and build carefully and make small bets only and not allow them to run too far in the red without stopping at a limit of dollars or in per cent. Old traders will still do this but their experience makes it possible for them to go with larger positions than a newbie. I have come to the point of having the guiding principle of all sales all the time. I don't deliberately buy much of anything. What I own I will sell calls against. When there is little to sell calls against then I sell naked puts well out of the money and in small amounts. When I have a good profit I might offer to buy back cheaper but often wait for an expiration as worthless or if assigned something to sell calls against. I should have gone this route when I was younger, it avoids a lot of bad buys. The real caveat here is to sell puts when the market is really bad so that in recovery you do not get assigned. When the market is high just concentrate on selling out of the money calls that will make you better off.
