What is Cloud9Trader

Cloud9Trader is a platform for algorithmic trading that runs in your browser. You write an algorithm, test it against past prices, tune it, and then let Cloud9Trader run it for you on a demo account or on your own broker account.

Trading on margin can lose you more than you put in. Past results, including backtests, do not predict future results. Cloud9Trader provides tools and education, not financial advice. Read the full risk warning.

What you can do

Section titled “What you can do”
  • Write algorithms in JavaScript. An algorithm is a script that runs each time the price updates and decides whether to open or close positions. You write it in the editor on the Algorithms screen, and every saved version is kept.
  • Start from someone else’s work. The Community Shared Algorithms list holds algorithms other people have shared. You can clone any of them into your own list and change it.
  • Backtest. A backtest runs your algorithm against past prices and shows what it would have done: its balance and equity over time, every position it opened, and its logs. You can test on minute data, which is quick, or on every tick, which is closer to live trading.
  • Tune settings with externals. Settings you want to change without editing code, such as a stop loss in pips, are declared as externals. You set their values each time you start a backtest or a trading session.
  • Trade with a demo account. A demo account uses real-time market prices and a simulated balance of 50,000 in US dollars, euros or pounds, so you can practise without a broker or real money.
  • Run trading sessions. A trading session runs your algorithm continuously against live prices and places its trades on your account, while you watch its profit, positions and logs.
  • Trade by hand. The Exchange and Platform screens show prices, charts, balances and positions, and let you place trades yourself.

What it costs

Section titled “What it costs”

Creating an account and a demo account is free. Backtests use backtest compute units from your plan, and the New Backtest window shows how many a backtest will use before you start it. Every plan, including Free, can backtest on every tick. Running trading sessions needs a paid plan.
