Is this on a real account? Are you aware that the standard capital requirements and such quoted in the manual are for a 100:1 leveraged account?

With the margin slider at 60 and an account leveraged at 500:1, you're looking at volume of $30000. The figures in the manual are 50 on a 100:1 leveraged account, for a volume of $5000. You're trading 6x as much as the quoted figures and should expect most of the numbers in the manual (particularly required capital) to be roughly 6x as well. For Z7 that means you need ~$3600 capital. With the 2x required capital recommendation, that's $7200.
