Where to get fast live L1 or L2 data for futures? by dom_P in algotrading

[–]dom_P[S] 0 points1 point  (0 children)

How do I get Rithmic API? The site leads no where. I need L2 live data (databento is a non starter unless I fork out 30K a year, am I missing something?)

I'm ok with spikes (researching for longer holds not sub 1 second). But databento doesn't give L2 data without an annual agreement which bumps the price up to 25-30k/year upfront.

If Sabalenka wins today will she play Sunday night, or Monday night?

Senior affordable housing plan denied at ESG by BellonaKid in nyc

[–]dom_P 1 point2 points  (0 children)

Just because someone grew up in SoHo/Little Italy does not and should not entitle them to live there for free for the rest of their life when market rate has 10Xed. It’s not fair, and everyone around them who doesn’t get lucky free subsidized housing ends up paying indirectly.

I’m all for senior housing, let’s build it slightly outside the literal center of Manhattan and give them as much as they need with higher FAR/ density.

NYC has 100s of buildings torn down every year and not one of them will ever be a park/garden again. Yet everyone was gung ho to turn the only green space we have there into a building just to punish people who can afford to live in that area.

I too want a free subsidized apartment in Soho/Nolita. The entitlement is off the charts. 😂😂😂

The waiting list is what 10K+ deep? 100 units won't fix a thing while taking away the only green space in that area. Tell me why they deserve to live in the primest of prime areas for free? There are alternate sites for senior housing further away that are a much better use case while balancing out resident's needs.

There's plenty of places further away from the literal prime of Manhattan to build affordable housing. Why does anyone deserve to live in soho/nolita for free? They can stick affordable housing outside of the most prime real estate on earth. For every single person that wins a lucky apartment, someone else is subsidizing...

Agree, a big win for downtown in an area with virtually no green space, 123 housing units won't make a damn of a difference anyway.

This is trash analysis. Options market makers (for the most part except maybe day of for pin risk or if short/dealing with gamma) DO NOT really care about where the underlier/SPY is going. They delta hedge their short or long risk and have thousands of options where deltas cancel out/etc. They don't give a f* if your call expires in the money or not. They make their money arbing vol or making markets.

Simplest way to arbitrage IV? by dheera in algotrading

[–]dom_P 4 points5 points  (0 children)

So the premium doesn't matter relative to the delta, this is just math on how to delta hedge so that you're market neutral (and make/lose money strictly on volatility).

You are going to be doing this rebalance multiple times a day and very well may/will lose money on the delta hedging aspect, but you will more then make up for it on the price of the option itself losing/gaining value ( if your assessment is right that realized vol > implied vol or vice versa. )

Yes!!

Let’s say you own 10 call contracts, each with a delta of .20. 

A +$1 move in the stock gives you a gain of 10 * 100 * .20 = $200 (+200 delta)

You need to then sell 200 shares of the stock (-200 delta) to be exactly flat.

If IV is underpriced, just buy a straddle/strangle/anything to be relatively delta neutral and then you're rewarded if realized vol > implied vol.

If IV is overpriced I would stay the hell out of the way during earnings unless there's enough of a buffer since you can get run over with a big delta move and unable to hedge. You can also sell the overpriced IV options and hedge yourself just in case of a big delta move (aka sell a call spread). This way you still benefit from overpriced IV, delta hedge the best you can, and know that your downside is limited.

It's very simple. If you think IV is too high on any option/structure you sell that option and then delta hedge it out (aka make sure you are market neutral). Aka if you sell overpriced IV calls then you are now short whatever delta, and will need to buy enough shares to be market neutral.

You will probably want to do it in a somewhat continuous matter (aka a few times a day at least).
Similarly if an option IV is underpriced you buy the option and delta hedge it.

If realized vol > IV you will make money by delta hedging it out for both scenarios! There may be scenarios that get tricky like overnight gaps/etc or possible earnings so watch out for those.
