Selection
The case was selected from its existing simulation record. Earlier valid marks remain and later valid unfavourable marks are retained. Broker historical daily values are identified in the downloadable source record.
Simulated portfolio record

Data sources
The curve combines recorded simulated-account observations and historical daily values reported by the broker, on the same base-100 index. Metrics use these reported marks and their dates; observation clocks differ. Monthly change is measured between each month’s last reported mark, with the opening or current incomplete month labelled partial.
29 July’s reported daily value disagrees with intraday account history and its close remains unverified. A fresh download reproduces the stored broker series; complete independent close reconciliation remains unavailable for some inactive securities.
Limitations
The series shows how the selected process has behaved in a broker simulation since formation. It does not establish realised fills, borrow, latency, rejected orders or live capacity.
