Managing trades with automated live model

For a live model with automatic rebalance, rebalancing happens either around 4am Central every Monday or around 10:30pm Central every Sunday. Early Monday morning prior to EU markets open is not always the best option for me to enter my traders so I was wondering if I could prepare them during the weekend. Obviously the Factset update is the main issue here. Is there a specific moment during the day when it comes in or is it continuous? When does it happen on Sunday? Below the answer that I got from the P123 language GPT which suggest that it is continuous.

Since you're in Europe, and the Portfolio123 early rebalance runs at 10:30 PM Central (4:30 AM CET / 3:30 AM GMT on Monday), the challenge is to check for trade changes before the European market opens on Monday (which is around 9:00 AM CET / 8:00 AM GMT).

Optimal Workflow for Early Trade Preparation

Goal: Ensure accurate trade preparation before European markets open while minimizing the risk of discrepancies due to FactSet updates on Sunday.

:one: Check the "Proposed Rebalance" Late Sunday Night (CET)

  • Timing: Check between 11:00 PM - 12:00 AM CET (5:00-6:00 PM Central Time on Sunday).
  • Why? By this time, most of FactSet's fundamental data updates for Sunday should be available.
  • How? Go to your Portfolio → Rebalance → Proposed Rebalance to see the upcoming trades.

:two: Compare It with the Latest Holdings & Rules

  • Manually verify if any fundamental metrics affecting your buys/sells might still be subject to change (especially if you're using earnings-related factors).

:three: Make Preliminary Trade Decisions

  • If the proposed rebalance looks stable, you can start preparing trades for the European market.
  • Mark trades that have a higher chance of being affected by late updates and be ready to verify them in the morning.

:four: Quick Final Check Monday Before Market Open (CET)

  • If possible, log in early Monday (7:30-8:00 AM CET) to do a quick refresh of the rebalance.
  • If no new updates have been applied, you’re good to go.
  • If the system shows new trades, you can quickly adjust before executing your European orders.

Summary of Your Best Timing (CET)

Time (CET) Action
Sunday 11 PM - 12 AM Check proposed rebalance (most FactSet updates should be in)
Monday 7:30-8:00 AM Quick final check (if possible) before European market opens at 9 AM

:small_blue_diamond: If you can’t check on Monday morning, the Sunday late-night check is your best bet. Just be aware of potential last-minute FactSet updates.

See https://www.portfolio123.com/server_status.jsp and scroll down to "Data Update Schedule." Your best bet is to place trades after the Sunday full load, which usually completes around 11 pm CST. If you need to place them earlier, then you can place them anytime after the full update on Saturday morning, which is usually complete around 11 am CST. Between those two times there are no updates.
