Exercise steps

1. Change the timeframe amount on Data Source.
2. Inspect Bars, Last Bar and Symbol: a subscription supplies data without starting execution.

Start lesson

Match data to the activation

In the RSI Starter, choose BTCUSD and one-minute bars. Connect the Bars data output to Indicator's Bars input. Event Trigger separately starts each bar-close evaluation for BTCUSD at the same timeframe. Choose a Backtest period with enough available bars for RSI(14). If the data source uses a different symbol or interval, the graph may be structurally valid but the comparison can describe a different series than the triggering event. Check both node settings before interpreting a signal.

Data Source is a provider of market values, not an execution step with Match or Submitted branches. A missing data window can leave Indicator without enough history; it is not equivalent to RSI 0 or a false comparison. Inspect the Backtest period and available data before changing the Condition threshold. The RSI quickstart shows where this connection belongs in the five-node graph.

Common problems

Data Source supplies data but does not start control flow. Align symbol and timeframe with the activation when the comparison depends on the same market series.
