buy less than 0.1 lots or decrease leverage?

Is there a way to buy less than 0.1 lots in ODL-Metatrader? Something like 3% or 5% of NAV? Because I buy 2 lots 0.1 each (I think my leverage is 50:1) and I see that my pip value (and margin remaining) is ridiculously high and low, respectively. While 0.1 is the lowest value in the metatrader, maybe there are scripts how to buy fixed % NAV? Or should I just change my leverage? BTW, how do I change my leverage in ODL-Metatrader? I set it once when I created an account and I can't find it since.

any insight would be appreciated

I just looked and don't see anyway to change the leverage on the account once it is created. I assume you are talking about a demo account. If it is, just create a new account and change the leverage to whatever you decide. If this is not a demo account, contact ODL directly and they should be able to change your leverage.

it's demo
