you should move square-off time from 3:10 to 3:15
Initially when we had started we had kept the auto square-off time at 3:15. However, there were a few occasions when we suddenly faced an issue with the auto square-off which happened from our backend vendor Thomson Reuters. Doing the auto square-off at 3:15 left us with very little time to have it rectified. In case of an issue, the time of 15 minutes is a little less for the below steps
1. First troubleshoot it at our end so that it's not a false alarm
2. Get connected to the right person at backend vendor, explain the issue to him
3. Have him check the issue and then resolve it
4. Run auto square-off from our end
Doing it at 3:10 pm gives us an additional 5 minutes which does not sound a lot but can still make a difference in case of an issue.
In the world of technology if one says there'll never be an issue he is fooling himself.
