- Transfers: a close books its SETTLEMENT and COMMISSION under one
transaction code, and keying by the code alone let the commission
overwrite the P&L. Keys now carry the type, so the day-start balance,
daily-loss room, realized P&L, daily history and books check all see
closed-trade profit and loss.
- Volatility from a week of hourly closes (was 48 h), still measured once
per trade date, so one quiet weekend can't triple a hold estimate.
- Each symbol's margin rate from the account's instrument details caps
the position at available funds / rate (Tradeify: 5:1 crypto, 2:1
stocks); the account type's max notional stays as an optional ceiling.
- Firms with overnight financing add the swap a winning leg is expected
to pay (the winners' mean hold, (A²+2AB)/3σ²) to its take-profit, and
the sizing and hold estimate count it.
