Fford the big loss so i prefer to invest less amount that i can afford in future if any loss can incurred then I'm not surprised to hear that you washed your balance while when u are new u should not need to invest more and If you are making money with both then you can think of a small deposit of $100 till but at this time i am at proffesional level that you know that many trader face lose in their first trade instead of dear if you have 10 dollar then make daily target like to dollar i mean to say that use lot size
