Hi Maksim, you certainly get around, I'm now answering a third question for you - glad you are finding Trulia useful!
I would not get too hung up on whether your property is 1 or 3 days on the market at the time of a first Open House. Days on the market has a drag effect in a declining market as it builds, but that is not an issue in the first few weeks.
What I think is more relevent is your readiness - let me be more clear. When I load a listing into the MLS, I am ready, with details AND photos. Loading the skeleton of a listing in is a blunder in my view because you miss the opportunity to have a big impact with folks set up on auto email services. New listings will feed out to them automatically in the night, and so they will see the skeleton listing rather than the robust listing with photos....opportunity missed.
Another consideration is to get your listing in early in a day so that it hits the MLS "hot sheets" during the agents work day - agents tend to look at the beginning of their day and periodically throughout.
So be ready, load in a robust listing WITH photos - quality and quantity count - and try to get your listing in as early in the day as possible.
