E_RUN_001 — Backtest run before set_strategy()

BacktestRunner.run_*() was called without first attaching a strategy via set_strategy(). The runner needs a strategy to know what to do with each bar.

How to fix

import flox

runner = flox.BacktestRunner(reg, fee_rate=0.001, initial_capital=10_000)
runner.set_strategy(MyStrategy())          # ← required first
runner.run_csv("data.csv")

const runner = new flox.BacktestRunner(reg, 0.001, 10000);
runner.setStrategy({ /* ... */ });          // ← required first
runner.runCsv("data.csv", "BTC");

Common causes

  • The strategy class was instantiated but never passed to set_strategy().
  • Code was refactored and the set_strategy() call accidentally removed.
