Good to know

Arena for business
The sandbox
Start with $100,000 in paper dollars. A contract pays $1 if its side wins: at 56¢, $100 buys 178.
Before you pay
One single-bet paper trade a day is free once you sign in.
API keys
API keys on any account: 1,000 requests a month, 10,000 with Arena Basic. A key can place paper orders when you turn on trade:write.

Paper trading is Arena's sandbox. The membership pays for the tools, not for an edge on outcomes. Subscriptions renew until cancelled.
