Thank you. He was a good friend and I'll miss him. Hopefully, I'll be moving out of the NYC semi-permanently and then will consider getting a puppy again. Indeed, it's all of the above and they are an "industry leader". I can't recall exactly, but I think they were down ~15% in 2018, down...

The ultimate examples are all of the flash crashes we have experienced in the recent past. The idea is that if they find themselves in an environment where they might have to carry inventory beyond their horizon, they will stop providing liquidity. If you have access to order book data, you can...

You are not portraying yourself as a seasoned systematic trader, unlike @syswizard or @stochastix (though it's also possible that they are trolling), so you can get away with not knowing who the key market participants are. AQR (https://www.aqr.com/) is a large systematic asset manager...

Dude, if you don't know what AQR is, you should not be in this business.

Unlike the real trading costs (which is pretty hard to estimate), slippage is fairly easy to model by simply introducing a delay in your backtest.

NIFTY offers both. Unlike most other exchanges, their single name futures are pretty liquid too. The only catch is that you can't access these products unless you have a local entity. I used to trade these at my previous job and it's a pain in the ass to set it up.

It's not hopeless as some posters stated, but it's not easy either. The general idea is that you can't beat high frequency players because of technology costs, but you can participate in the game when they are not interested. So what you want is to provide liquidity at the holding horizons or...

John Griffin is at it again. Meh.

This guys tail is both flat and long :)

Just another point. If you are picking up pennies in the middle of the road and there are corpses of prior fortune seekers lying about, that should tell you something, no?

Since you wanna talk academically, here is something for you to chew on. First of all, It's very possible that the we overestimate how heavy the tails are because there are two components at play, stochastic volatility and non-normality of the distribution. The general idea is that if you...

We got that :) hodling aside, you don't think that there is a lot of FOMO at the moment and cryptos could correct a little from here?

I'd say it's a sign of the local top :)

“Americans are getting stronger. Twenty years ago, it took two people to carry ten dollars' worth of groceries. Today, a five-year-old can do it.”

More like expecting USD stable coin legislature to make EUR-backed stable coins more interesting Founded in 1754, as legit as it gets. And yes, they are real - I have seen them hit US banks for structured note hedges.

I'd always confuse volga, volvo and vulva

How about picking a book and reading about how options work? There are good ones for pretty much every level. I am in a wrong fucking business!

Well, what you care about is latency from your server to the exchange; e.g. what do you think is the ack time from the moment you send the order? Most of that will be flight time from you to the matching engine and back to you.

Actually, you can fairly comfortably build a second-tier latency setup on the cheap (like 1-2k a month) and third-tier for even less (~500/month), for either futures or equities. There are companies providing all the components - shared colocated servers and/or proximity hosting, retail-priced...

I am half-tempted to say that if it really does provide you with 86% accuracy, you can back out a trading strategy out of it
