Even 0.5 lots on $100 is too much and just a gamble. 0.1 lots is a lot for an account that size.
I blew a £1000 account in 3 days with lot sizes of 1 and doing what you’re doing. I didn’t set out to do that, but I was bored and thought it would be fun. Turns out losing money quickly isn’t that much fun.
Like I said, it’s not impossible that you will make money, but very unlikely. You should probably consider this; if a broker gives you 1:3000 leverage, what is their incentive? Why give you the chance to make huge amounts of money from them with a tiny investment? Because almost everybody that uses that leverage gives all of their money to the broker quickly.
Anyways, keep us updated with how you get on. Always interesting to see an aggressive account (except my own haha)
