for me i use 4$ per point as the max lot size and this make me lose a lot of money i have got that the risk not needed for the trader well who want to win the year is long and we take alway in our mind that what is the step after the lost the deposit so why we risk justtrade with this money and we dont need to deposit instaforex may 1:600 leverage use karta hu.iss liye mera highest lot size 1$ se jadya nehi hai.or aap isko 1.00 per volume keh sakhte ho.lekin lot size use karna depend karta ha balance and money management ka upar.
