How to begin this...?

Following 3 years forex experience I eventually became conscious of how significant MM the capability to shoot mor then 3 transactions at exactly the exact same time is.

I've an 300$ Mini-Account (0.1 Lots) on FXPro w/ a Leverage of 1:100
One trage takes ~100$ Margin. So I can 2 transactions at the exact same moment.

What do I must change, to be more stable?

Choice 1:
Trade Micro-Lots (0.01). Dont know if it is possible w/ FXPro - gotta check that when I'm at home. If anyone knows that, please post.

Choice 2:
Change Leverage. W / a Lev, as I know it. I can have more transactions at the time but will get Mergin Call very often. A smaller Lev.: visa verse. It is a two-bladed knife...

Choice 3:
But more cash into the account...

And another question:
With my preferences (1:100 Lev - 0.1 Lots) 1 Pip is just 1 $
If I change my Lev into 1:10 is 1 Pip = 1/10$ = 10c? Is it exactly the same as a Micro-Account w/ 0.01 Lots? How can a 1:10 Lev. Impact my Margin?

Thx for reading along with an extra thx for answering
