I have observed great number of traders debate on the issue of having a solid psychology and right approach to trading better pay off than just relying on some Strong Technical Analysis but others don't believe in psychology they base there points on having a winning strategy and proper risk management

Does Psychology exist or is just an illusion of you not having the right approach and risk management, fundamentals...that affect your trades
Committing a trade is not just you having the budget, the platform, the current state of the market. Also you need to consider your emotions, are you capable of making a trade or not this, might affect your decision making the market is volatile things might happen so expect a ride of emotions too one mistake can ruin your position or even your whole trade. For me psychological state has an impact to a person by this you can easily identify to yourself are you still on the ground to make a trade or you are too much greedy or hopeless to gain profit or just call this for a day.
