How do you backtest and paper trade a trading strategy on Stellar?

Guide · 17 October 2026How do you backtest and paper trade a trading strategy on Stellar?In short. Build the strategy as a workflow (candles, an indicator, a decision, a Risk Guard and a trade), then open Test strategy to backtest it and switch on paper trading. Deployed while paper trading, it runs 24/7 in the cloud on a simulated account.How do I build the strategy?A strategy is an ordinary workflow. A simple moving-average strategy on a Stellar pair looks like this:

Schedule to run it, for example every hour.

OHLCV for the pair's candles, wired into Indicator (SMA, EMA, RSI, Bollinger, VWAP, ATR or ROC).

Compare to decide: price above the average, or RSI below 30.

Risk Guard in front of any trade: it blocks orders once a limit breaks, such as a maximum drawdown or position size.

Manage Offer or a path payment to trade. Position tells the workflow what the account already holds.

How do I backtest it?Open Test strategy from the toolbar's flask button. A backtest fetches the pair's past candles and runs your workflow once per candle against a simulated account, then shows the equity curve and every trade. Nothing is signed and no real funds move.Know its limits: it tests one pair at a time, offers fill whole (no partial fills or queue position), Stellar's minimum balance isn't modelled, and blocks outside the simulation, such as an HTTP Request, return today's values. The report warns when one of those ran.How do I paper trade it?Switch on paper trading in the same panel. Every run of the workflow then trades a simulated account against live prices, and a Paper badge sits next to Run. Deploy it while paper trading and it runs 24/7 in BluFabric's cloud as a paper strategy, with its own simulated account. Still nothing is signed.When is it ready for real funds?When the backtest and a stretch of paper trading both hold up. To trade for real you run the workflow from the canvas and sign in your own wallet, with Risk Guard and, if you like, a Human Approval step in front of every order. Keep the trading account funded with only what the strategy may lose.Questions

Which indicators are there?

SMA, EMA, RSI, Bollinger Bands, VWAP, ATR and rate of change (ROC), in the Indicator block.

Can the cloud trade my real funds?
