Execution and rebalancing
A cluster on when a strategy should trade, how often it should rebalance, and how execution friction changes what looked good in research.
Reviewed by Alphora Research
Updated June 30, 2026
A trading signal is not the same thing as a trading policy. Two researchers can agree on the same signal and still get very different live results if one rebalances on a fixed schedule, another waits for threshold crossings, and a third assumes frictionless fills that never exist outside the backtest.
This cluster separates signal quality from execution policy. It links cadence, no-trade zones, turnover budgets, and portfolio constraints back to Alphora's validation workflow and portfolio simulator so the practical trading decisions are visible instead of hidden inside a parameter block.
