Risk management and if I open the pair I mast open how much

Hello guys I have a problem of risk management if my account is $101 I mast risk how much and I mast open the pair how?

Depent on ur account minimum lot,
With 0.01 lot and 50 pips SL,it will make u risking 5% ,
So if ur minimum lot is 0.01 i think u should have 500$ minimum capital.
But if u have cent account, 100$ is pretty decent

And i lost at your second question ,i dont get it
