I'm new to the forex scene, but I do have $10 USD in my account. I wanted to buy GBPUSD at .01 but the systems says I dont have enough money. .01 is 1% of $10 so why is it saying I dont have enough money?
0.01 is 0.01 lot of 100.000 units of the base currency, GBP in your case.
So 0.01 lot is 1.000 GBP.
Maybe it's time for you to study some of the most important things - Leverage, Margin, Balance, Equity, Free Margin, Margin Call And Stop Out Level In Forex Trading and you find an article RIGH HERE about this. Hope this helps you out ;)
The error is correct. You should not invest money but invest time in order to understand trading forex. There are books, there are websites https://www.babypips.com/learn for example.
