ARCA after hours newbie question

When a sale order goes to ARCA after hours, is it reviewed by someone before it goes public?

 

No. If you have access to extended hours trading, it should go straight to ARCA.

 

I supposed that if I'm the first one to offer my shares they will be bought first if me and someone else offer shares at the exact same price. Right?

 

You have to check the NYSE ARCA website to see if they offer time and price priority. I expect they do but they might allow crosses at your price.

 

Well it may be reviewed by your brokerage compliance department (especially for short sale orders) before it goes live. Other than that I don't think anyone else has access to your order before it goes live to the public.

 

Can you explain that further about review of ah shorts?

 

I think a "review" in this case means that the brokerage has to come up with a borrow.

 

Yes

 

Oddly enough, I saw this for the first time today (although, during market hours). Was shorting SNAP.
