Help and contact

Start with Troubleshooting. It covers backtests that will not start, sessions that stop and brokers that will not connect. For errors in your own code, see Debug an algorithm.

Email support@cloud9trader.com from the address on your account. Say what you did, what you expected, what happened, and when. Include the name of the algorithm, backtest or session.

Never send your password, a broker key or an API secret. Support will never ask for them.

To report a security problem, see Security.

Does Cloud9Trader hold my money? No. Your money and positions stay with your broker or exchange. Cloud9Trader sends orders to it using the keys you connect. See Risk warning.

Can I use it for free? Yes. Every account starts on the Free plan, which lets you write algorithms, chart prices and backtest. Paid plans add more backtesting and trading sessions. See Plans and credits.

Which brokers can I trade with? See Brokers for what each one supports today.

What language are algorithms written in? JavaScript. See Algorithms.

Can I try it without risking money? Yes. Backtest against stored prices on any plan. Running an algorithm on the demo account, or on a broker’s practice account, needs a paid plan, Basic and up. See Go live safely.

Can I change my username or email, or delete my account? Not in the app yet. Email support. See Your account and Privacy.

Is there a forum? No. You can share an algorithm with others. See Sharing algorithms.
