What's the difference between a stop and limit order?
If you don't own bitcoin, you won't be able to do trading at binance and there is no point to know what is stop and limit order. You need to have bitcoin first in order for you to trade.
First tell me in which country do you live and i will help you find out which is the best site to buy bitcoin. Also note that coinbase does not support all countries for buying selling bitcoins.
