I think you should add one more thing is the discipline of an investor. Because the strategy and plan of the trader is more important than anything. If the investor does not have a strategy, he will not get anything.
That is exactly correct. Strategy and plan is pf the prime importance and once you have a good strategy and plan, you would not find it hard to escape loss. But if you do not have one, be sure that the market slaps when you are not active.
