Temporal Coherence by BRETT HOLTON

| Reward Discussion

I am really struggling to understand when events happen in this system. I am trying to implement a basic algo that operates as follows

1. 20 min before close (Using scheduled event fired 20min before the close) buy 100 shares.

2. After the close that day calculate the Stop and Target for next day(Using scheduled event)

In the logs there are several time stamps, one driven by the Debug command and one from my printing the Time of the slice I am accessing. These times do not line up in any manner, I see info from the day before printed after the infor triggered by the endofDay scheduled event.

Is there a good example of managing time in the algorithms?

The data timezone of equity is New York time. The default algorithm timezone is the New York time as well. For equity algorithm, the timestamp in the console and the slice.Time should be consistent. Please see the attached algorithm.

We can not repeat the same issue. Could you please share the algorithm if you still find the inconsistency in the time index?
