Yes trading is easy.Just push the buttons.The trick is when to push it and get.and the most difficult part is when to get out.(Abhimanyu,Chakravyu).
The real problem is the traders psychology.
1. Expectations.
2. Unknown demons in the mind after a trade is put.
3. Reading too much news just to get ahead of the people.So that one can get early in the trend.
4. Too much leverage
5. Looking for confirmation bias in other instruments like SGXNifty,Dow futures.
6.Not willing to put time and effort to learn with patience.
7. THE MOST IMPORTANT - UNDR CAPITALISATION.
