I'm suggesting that the whole HFT issue is mostly scapegoating. The idea that a guy trading from basement caused the Flash Crash is ridiculous to me. What kind of markets do we have if that's true!? Why is it so fragile? I think I know - risk transfer from pros to individuals with the...

Regulators don't care about you and me, they protect interests of exchanges and their members - the pros.

Ah, I haven't been in the pits but HFTs just automated everything that they did in the pits. Most of the strategies came directly from them. Did I forget to mention that pit traders were co-located and had access to info before anyone else? Exactly, they have been made more efficient by algos...

Right, my point is that traders usually benefit from artificially manufactured moves. I'm still not clear who is being harmed by spoofing. I understand and accept @GRULSTMRNN point about fair markets, but who is being harmed? Someone mentioned instability. Ok, why large orders cause...

I'm thinking that there must be lots of people here that benefit form the noise created by all these manipulations. We don't want efficient markets do we? Just to stir things up :)

I scanned the list but nothing (except Iron Duck) caught my eye. Any suggestions?

There are so many more knowledgeable people here regarding this, but I think y have it backwards. Rithmic provides the service of connecting you to exchanges, it's kind of a middle man between you and FCM. They also do the risk checks for FCM etc. There are people who connect directly to...

I wanted to share this great analogy (imo) that Dr. Brett Steenbarger used in one podcast when asked same question: Imagine you are a surgeon and your patients keep dying on the table and after the surgery you say - Damn, something is off - I need to work on my psychology.

I was just kidding, although would be good to find a way to avoid using them. Something like running a shorter term strategy within a context of longer term strategy, so you just shift the loser from one to the other. I am not doing that, just a thought.

You must have been using stops ... Rookie mistake :)

Oh, so I guess understanding of the importance of the trade management. What is your definition of not working?

The major support area one, LOL

How can this be done other than averaging down? What was the point of the exercise?

I understand what they are trying to do - make sure developers do not develop unethical software - but at what point does developer realize that intent? What about generic algos that can be configured in a way to accomplish harmful behavior? It's a very blurry distinction. I doubt anyone...

Trump hasn't tweeted in a while but you are still grumpy? lol

Why can't you answer this question yourself? Just pretend you don't know the logic behind it and try to reverse engeneer based on available data.

I received below email from Robot Wealth. I thought maybe of interest for some people here. Sounds comprehensive, but I wouldn't know. We’re excited to announce that our Trading with Machine Learning and Big Data Bootcamp launches on Monday November 11th! By the end of this 6-week Bootcamp...

This doesn't sound right. You should get the ACK back first on OUCH which will carry the order id. I think what the above means is that they will not send you execution message on OUCH prior to publishing execution message on ITCH. So something like below: Receive order from customer Send...

Why MMs don't want them? Do they compete with you at all?

Wow, much Ado about nothing. Trading is a scam for 99.9% for people who try at retail level. One of the reasons is because it attracts all kind of degenerates. Legend? No, not in a Market Wizards sense of the word. Wall Street Veteran? Undoubtedly so. Actual Trader? Undeniably so. And, as he...
