Dear support at Sierra Chart,

Please can you verify which of the following is true or not true:

1) Day trading (for Day margins) = trading between 09:30 - 17:00 NY time?
2) Day trading does not include hours from 18:00 to 17:00?
3) Overnight trading = will then be trading any time between 18:00 and 09:30 NY time??
4) 'Overnight trading' only refers to when you let an open position continue to run overnight after 17:00 and into new trading day past 18:00?

I've been demo trading the equivalent of 00:00 hrs to 06:00 hrs (NY time) (my time being 5am to 12 noon) - but now - I may have to change my wake up time to trade later so as to comply with margin requirements?

Would be most grateful for your clarification of these terms, as I cannot find them in your Documentation.

Thank you.
