In Futures, instead of giving you the balance of the accounts, give you the number of contracts (standard/micro) that we allow you to trade. As we offer both US and EU exchanges, the margin required per instrument is set by us, limiting the contracts you can simultaneously have to 5/50 (standard/micro), 7/70, 10/100 etc.
The starting balance for the 1st level is $250,000, which we have set to allow you to trade up to 5 standard contracts or 50 micro contracts simultaneously. At Level 4, where you see that we allow you to trade 7 standard contracts and 70 micro contracts, it is because we increase the balance to $300,000. In Futures we know that the number of contracts offered to a trader, is more important than the actual balance, therefore we demonstrate it as you can see on the website.
You can find the list of our futures instruments, along with the tick size and tick price for each instrument here.
