Synthetic contracts are calculated from closing day prices. Therefore, the typical trading day is made up of three distinct parts:
- Morning Reports: Operations staff work with end clients to agree previous days margin account balances. New synthetics trades and modifications are entered on demand.
- System Sign-Off: Operations staff have finalized the margin account balance & payments with end clients. Xylinq prohibits any changes or modifications which would cause a change to the contract valuations. Only new synthetics trades for today are allowed.
- End of Day: Review any Reset-Rewind events created by back-dated changes; Xylinq is loaded with closing market data and it calculates the day’s contract valuations and updates the margin accounts appropriately.
