I've got a new one here - controlling your emotions.
Controlling your emotions while setting up a trade is one of the major aspects a very few people know and this thing can't literally be taught to any person as it needs to be conquered on our own. I believe that OP should compile a list of such opinions and put the best ones in the first post so to give a glimpse of the points that are needed to be taken into mind and learnt on our own before jiving into trading.
Yes. Emotions in trading can't be taught or totally controlled because even if your trading ends with profits or losses, your own emotions will still have its own place in trading. They say controlling our emotions is a must in trading but i think it's just easy to tell but finds it hard to do when we are in actual trading.
