/**
 * One portfolio, priced. Open lots are rolled up into a position per instrument, each
 *             marked from its own price lane and labelled with the trading session that mark belongs to; a
 *             position that could not be priced carries nulls and a reason rather than a zero. Closed lots
 *             are listed with their realized profit and loss, and instruments watched but not held come in
 *             a separate `watching` array carrying marks only, outside every total. Totals are in the
 *             portfolio's `currency`; each position and lot states its own currency, with its figures
 *             converted at the official rates listed in `conversionRates`.
