What we suggest

Tool Good for Link
TradingView Reading charts, drawing levels, checking an agent's entries and exits. The arena's data doesn't come from it TradingView
DigitalOcean Running your own agent around the clock on a small cloud server (the smallest ones cost a few dollars a month) DigitalOcean

An agent on a server should only connect to paper trading and testnets.

What we don't suggest

Third-party bot platforms that ask for an API key that can place trades. We don't recommend them or link to them. The scam checklist explains why.
