May I ask why you don't want to host your own server? When I was looking for colo to trade futures, I found Steadfast. I spoke to Jeremy who was extremely helpful. They have 10g to Aurora. https://www.steadfast.net/why-steadfast/our-data-centers-network/data-centers

It's funny, when I read the article I replace "programming/tech" with "trading" and end up with the same business model ... Take thousands wide eyed optimists, tell them the success stories, charge them for education(not in this article, but most do). I suspect 1-5% will make a career out of it...

Strongly disagree. Cannot take a an online class for that and be consistently profitable in a few months. Obviously without knowing your situation I cannot know what is best for you, but I agree with what @nooby_mcnoob is saying. The industry had changed a lot from when I started. If you like...

It depends on the existing system you have in place. Most real time systems have multiple components which need to communicate with each other without introducing delays ... You can't just pend on a single queue waiting for events(or poll multiple queues). I believe some people reverse...

Agreed. The only way to get a good estimate is to clearly and fully define the functionality required, otherwise expect to go back and forth and pay by the hour. Don't forget that both quickfix and IB API requires multi-threading which makes it more difficult to integrate into existing...

I don't believe this was true before, did this happen after the Lightspeed merger. BTW, thanks for answering ... Was hoping you would.

I am curious, do you guys really think they are doing something extra ordinary that no other mind in the world can conceieve? I suspect it's more about relationships, access, technology, etc. For anyone who signed NDA it may be impossible to replicate the strategies in scale without anyone...

Unless I misunderstood, isn't it essentially same as below? https://fourweekmba.com/barbell-strategy-taleb/

I don't think it's that easy ... Got to set up some infrastructure and establish some relationships. Deal with noobs, paper work. The turnover must be huge. I wander if they get to share some percentage of the split if the account gets funded. That would be more attractive. Who is stopping...

Checked a few more ... the 230ms seems to be an outlier, 40-100ms seems to be the norm, but I'm running lots of GUI on the Windows box with multiple monitors so maybe due to my machine performance.

I checked a few out of curiosity ... good info to have in any case. My ping is 15-20ms. As printed in TWS Api logs EST time on Windows: 11:15:06:227 <- placeOrder() >>> 230ms 11:15:06:457 -> "Submitted" 11:15:06:662 <- cancelOrder() >>> 37ms 11:15:06:699 -> "Cancelled" I'm not proficient...

You may be right about that, but I am not sure your example is a good one. Stock moving 5c below best bid is not exactly a flash crash. I think if you want to get filled at a certain price, dark pools should be ok. If you want to play speed games, IB is not where you trade.

Did you confirm that via time and sales - preferably other than IB's. You are talking about stop order, right?

If you achieve that goal, that would either mean you are having a lucky streak and/or current market conditions are very favorable for your way of trading. In either case, you would be pressing the account too much, imho. It's about risk adjusted returns, not absolute returns, right? I assume...

Don't you think it would be a red flag if someone doubles account in a few months? What does it mean for annualized returns!?

In what time? A couple of months?

Hold on there a second, we are talking strictly profit taking exits, right? Break Evens and/or loss exists is a hole different animal ... Deserves a separate thread altogether :)

I guess it all comes down to individual psychology. For me, seeing it keep running into "unreasonable" territory without me is unbearable :) Have to keep at least 1/4 runner however low odds(trailing with wide stop - 50% retrace is ok). Screw the stats, gotta have some excitement!

I suggest you modify your current system to connect via socket to a server. Implement some simple protocol ( buy 100 XYZ 12.35 SMART) Implement all the functionality that you will need to have (I would start with #3 and left rest as is). Once you have that, simply give your protocol spec to...
