emotions greed and panic is always bad for trading we have read many rules in books and we did experience those in real trading but this takes time to improve our emotions
Emotions are always enemies for our trading plans. No books will help you to tackle your emotions while trading but only your experience may help you. That is why pro traders always emphasizing about mock-trading. Through experience we can handle our emotions effectively so that we will not take decisions due to emotional failures.
I have been trading for a year now , and still I'm not even close to being able to control my emotions. It had lost me so much money and I feel frustrated and almost close to quitting because I think this market isn't for me. I guess the problem is the fact that the money I have on cryptocurencies are my only funds and my only source of income. This makes it harder for me to not get emotional when my holdings start falling ,which drives me to make irrational decisions to try and recover somehow.
