You have to discriminate between building a Ferrari, a BMW and a Wolga. My statement is for building a Wolga
、 Even u can create a HFT system, retail level brokerage fee would make it not profitable. That's why only ibank kind of company can really apply it.
Cool, then you build yours with C++ back-end and C#/Java front-end? I cannot imagine C#/Java can be fast enough for your high demand back-end.
I think it depends on how much % do you want per year. Let's say I am happy with 10% annual return, but your goal is over 50%, then we have different target and way to achieve it. You may need HFT kind of level, but I don't need that for my goal. I am not saying I am lazy and just happy with something like Amibroker, and I may take much longer time to discover something that is easy for serious professional, but I still have a full-time job and doing all of these as part-time own interest so I am fine.
hftvol, I agree so far you are the most experienced systemic trader I have seen in the internet world. Then do you think this Japanese guy story is real or fake? http://www.japanprobe.com/2008/05/20/takashi-kotegawa-bnf-super-day-trader/
You can find out more about him by google japan bnf or some terms like that. Look like he just looks at numbers then can day trade. He mentioned little bit about his way and sound like trend following.
Your words let me come up with these questions: 1. Is it even possible to have regular profit with a simple/not math research paper level strategy? 2. Big profit can only be made with insiders news? Ibanks and others like them may have insiders news, but you don't sound like you have or include this factor in your trading, then are you sure you can beat them or win with them? If the answer for 1 is possible, then someone designs an alright complicate trading program may has pretty good earning for himself.
Wow! with each passing day this thread is getting more and more humorous. Here we have one guy going on for days talking about how great he is, and why the only solution to profitability is to code up your own platform, while turning a blind eye to the fact that most people on this forum simply don't have the capability to code their own platform. And the other guy keeps asking irrelevant amateur level questions. Very soon, we will see hft dude will come again and reply for pages to the OP and the whole cycle will repeat again. LOL.
I am not professional level yet but also know HFT is not that possible with retail brokerage cost. May be he has his own Investment bank, who knows.
Yes your questions make it clear that you are an amateur. Which is fine everyone starts from somewhere. My recommendation - get a trial of amibroker and if you want, also spend 2-3 weeks working with tradelink to see if you will like to go down that route.
