Hi Everyone

How do I increase my open trades on Z4 and more importantly the usable margin?

The script is only keeping my margin at 95%, buying 1K currency at a time.

I am a high risk user, and I'd like to increase my usable margin to about 50%.

Could someone please advise on how I can alter Z4 or which strategy I should change to?

Thank-you for your time. This community is providing incredible insight into my financial understanding.

From what I observe, you simply have to move the "Margin" slider to the max (10) and you can also increase your "Stop" slider to the max (1000). (Keep the "Mode" slider to 1). This will give you (in test mode) a profit of $1251 instead of the default $818.
I would recommend you make sure to read the Zorro manual on the Z4 system first + trade in demo before going live.
