must for trading!

Friends main ne trading men note kia hai k jab hamen loss ho rha hota hai to ham apni trades ko open rakhte hain but jab ham thorase bhi profit hota hai to ham apni trades ko close krne men jaldi krte hain, dear kia aisa hamare emotions ki waja se hota hai.
Plz reply me......

jee ha sir ya to apnay thk kaha ha kal mene aek currency pay trade kia to mujay 20$ k loss ho raha tha or mane sell lagai thi lakin mera dil raha tha k ma us pay again sell laga do ya buy lakin mane phir market ka wait kia phir market buy jati jati again sell pay a gai thi jis say mujay wo 20$ ka loss bhi katam hoa or mujay profit hoa islay apko wait krna chahiye

Bilkul dear ap ki bat darust ha k market up down move karti rehti ha r hum loss wali ko to close ni kar sakty r wait karty hn us ky profit mn any ka but ptofit wali jaldi kat dety hn k kahin market reverse mn jaye r profit loss mn na badal jaye.ye hamary emotions ki waja sy hota ha.
