psychology and emotions contributes mostly to trading success or failure, I think they both have equal weights in effect on an individual in the trading industry
For example indiscipline may most likely have the same effect as fear or greed on a trader per time....what you think, does one have influence more than the other and how?
Our psychology works the same line with how we react emotionally to situations when it comes to trading and taking some decisions on it, but there's a way we could cause a balance to them both by the way of reasoning towards what to do, how to do and when to execute that same intention on how mind, the psychology behavior of a trader works with his feelings, which tells more about the possibility or feasibility of getting something done in the best way to acheive a quality result, while our emotions will tells on how we have acted upon such feelings, being a trader, we need to learn how we could fix on these and make them all work together, this will help maximize our trading performance each time we are on it.
