Rebuild it in Orbital

Paste this into Orbital Chat. The Strategy Developer builds the workflow and asks before it runs any backtest.

Trade the sector ETFs XLB, XLE, XLF, XLI, XLK, XLP, XLU, XLV and XLY on daily bars, deciding on Fridays only. Buy an ETF with 25% of equity when RSI(14) closes below 35, most oversold first, and sell it when RSI(14) closes above 60. Long only; uninvested capital stays in cash. Backtest the last 10 years with $100,000.

Read this before you trust it

Each position is 25% of equity, the original cap, and is decided on Fridays only. When more than four sectors qualify, the four most oversold are bought, where the original split the account among all of them. No rebalancing between trades.
