They are just trying to reduce headcount without FIRING them.

it's absolutely NOT a closed end fund. Here's a chart of the shares outstanding. NOTHING BUT DOWN. https://www.marketscreener.com/quote/index/ARK-INNOVATION-ETF-SHARES-39466325/graphics/

Not even with your tool....

So you're traveling back in time now?? (asking for a friend). She's lost more divestor money than I can count. Life to date loser in gross $$. Same as Paulsen and many others. +200% on 1b and then -30% on 10b, yes that's a massive loss in gross $.

Only thing worse than divesting in her funds would be having to "DO" her. Not even with my worst enemy's tool.

Your packets are LARGER than OPRA binary packets. And MBO (as exegy and others define it), is ORDER BOOK DATA. This is NOT contained in OPRA. It's ONLY available in the direct exchange feeds. If you are COMBINING multiple exchange's quotes into one, creating a "book of sorts" which is ALL...

56-80 * 10m = 560-800 MILLION BYTES PER SECOND. A BYTE IS 8 BITS. 4.480-6.400mbit (AND THAT'S NOT COUNTING TCP/IP OVERHEAD). Please. Stop. 10m/second IS A REAL NUMBER. Maybe you can just look here and see for yourself. https://marketdatapeaks.net/ If you have an account there, then you...

OPRA absolutely has NBBO appendages. All SIP feeds do. Not sure exactly what MBO is (your term). Not going to argue the bandwidth any further but your math does NOT add up. Quote traffic is REGULARLY 10m/second+ for periods exceeding 5 seconds. That puts the bandwidth requirement above...

Taiwan Haiwan Lee!!!!!

Thank you for the detailed update. I'm not interested in the published NBBO or your L3/MBO. I want the individual exchange quotes. All symbols. You're correct on Nanex time resolution. 1ms is the best they do I believe. It's not "lossy" beyond that from what I recall when I used it...

They fired anyone useful. Everything outsourced to India. Might be ok if you enjoy curry...

What is the typical byte count per quote?? I can go from there.. OPRA, today, runs 10-12m/second rates for EXTENDED periods of time. "bursty" goes WELL above that as you are aware. I'm trying to determine bandwidth requirements based on the size of an individual NORMALIZED quote record...

Don't see how this is possible. Let's say you're REALLY good and get an individual quote down to 15 bytes. at 20m/second, that's almost 3gbit. Just for one side.... Is there a "blanket subscription" method whereby one can say "give me EVERYTHING"? AND I'm probably radically overoptimistic...

And what is the price for all of the magnificence?

Buffering? Really? What if you can't tolerate such? Why have a realtime feed if it's late? How much bandwidth to assure none of that? And what do you mean by "per side"?

Realtime, as in you can deliver 20m+ quotes/second?? Really?

Right around the corner... MIAX Sapphire. OPRA code "S"!!!

I should have looked at the trade more closely. Your trade as shown is LONG the box, not short it. And if you're actually going to sell it, the 438 call (next week) was an exercise. The dividend is not yet published as I type this but estimated to be $1.68, so your short 438 call was...

100% gets jammed for for div.. full assignment.

I believe Nanex can provide what you're looking for
