ACSIL – Rithmic order/fill timestamps When using Rithmic Direct-DTC with an ACSIL automated trading study, I want to measure order execution latency. For an order submitted through ACSIL, can you confirm whether s_SCOrderFillData::FillDateTime represents the fill timestamp received from Rithmic, and whether it retains Rithmic's millisecond precision? Also, is there an ACSIL-accessible timestamp representing when Rithmic acknowledges/accepts the order, distinct from the local submission time and FillDateTime? I'm looking to measure: local submission → Rithmic acknowledgement → Rithmic fill → local receipt of fill with millisecond precision.
