Every trading night at Aberdeen Standard Investments, a carefully orchestrated batch cycle ran to prepare the platform for the next trading day. After market close, CITI (the custodian bank) transmitted end-of-day position and transaction data via a secure channel. This triggered a pipeline that reconciled positions, applied market prices from Bloomberg and FactSet, validated compliance metrics, loaded cash balances, and recalculated risk exposures — all within a fixed overnight window before the trading desk arrived in the morning.
