I am almost certain ARCA or Archipelago would be the Archipelago Exchange/network. It's one of many, private "networks" where "big boys" can use/send order flow to match a buyer and seller. So it could be a place where the broker/dealer or an Asher like firm is sending some big order flow to get a "match" and make a sale. Those networks are very hard to decipher. Read up on "dark pools" and the like- those private ECN (electronic exchanges) are used a lot of time to make sales for a big client who doesn't want to be identified. Or, it can just be firm XYZ who wants to sell or buy and happens to be a member of that electronic trading network- and can use it to route order flow over to look for a "match". Hard to say. Are you seeing what looks like big selling or share volume stacking up on it? That would maybe indicate someone trying to move a large chunk for a big boy. Also, these broker/dealers have an entire bag of brutal tricks they use (think Asher) where they can "flash" orders up on these networks to get panic selling going, or go short, then they pull that order away- never intending for it to even fill, then "flash" it out their again to mislead people that a big sell is sitting out there- there's all kinds of games/shinanigans that go on. Hard to say just by seeing the broker/dealer symbol or network symbol like ARCA. Some of the real "boiler room" broker-dealer otc/pink symbols are notorious and real well known and tend to be a bad sign when you see them roll into view. But ARCA as far as I know - is someone using that network to route some order flow. Google ARCA, Archipelago network. I will say- it's a well known network for hedge funds and big, private trading firms to use, that's pretty well established- what their motive is in this case and are they buying or selling a chunk for someone can be real hard to decipher with what us "little guys" can see/know.
