After entry, the account bears losses from adverse price changes, slippage, and costs. At each management point, ask whether continuing the remaining exposure from now, given current information, is preferable to reducing or exiting. Past fills and incurred costs belong in total performance, but having already paid them does not justify further risk. Asking whether one would establish equivalent exposure at current prices, boundaries, and costs if flat can test the holding rationale, though existing holdings also involve exit costs, taxes, and limits on instantaneous execution. Before holding, specify expected price development, its location, how long to wait, and behavior indicating a weakening view.
