API Trading w/ Thinkorswim

[inthefutures]

Its not that difficult, depending on your committed capital size. But probably not something a 20 yearold should try from Mom's basement

Or, you could simply buy VIRT stock - check out their chart since mid_February - they benefit directly from higher volumes, wider bid/ask and volatility.

coding the back end order management for day trading is not that difficult? However that is where most who try to automate trading fail

Not sure what you mean by 'most' - plenty of firms do it everyday. If you mean a one man/woman band creating their own code, and with limited cash AND unable to sustain some losses along the learning curve, sure, its impossible.

Which is why I suggested earlier to read VIRT's IPO, and other disclosures on how they operate to understand the infrastructure required, before thinking about trying it. As always, the Devil is in the details, such as, their credit lines, their staff , trading levels etc and the other article which describes their road to success.

I have the money as well as working tos strategy's. I'm just looking for extra income while I'm in school because I'm trying to learn, not trade during class. Also VIRT does look good but what does that have to do with any of this.

was only talking to the name of the thread "Has anyone here ever tried to algorithmically trade? was thinking this was a question towards the individual,

VIRT is a major player and their disclosures are a unique insight into the algo and HFT market.

Their disclosures detail quite a bit.

Does anyone know how to code a script to show open interest data from TD Ameritrade API?

 

[CGD]

Good morning, a favor, I am also new to this forum, I am trying to do a study but I am a beginner in the programming language, and much more in thinkscript, I am trying to read the price or real value live, but the only tool What I found was "close", but this gives me the price of the closing of each bar, and I want to read the price at all times, someone can help me by indicating the function for this.
thanks.

Does anybody have any recommendations for API programmers for ToS who can automate trading?

Hello I am trying to connect to the ameritrade API using C# . I cannot get it to auth and was hoping someone here has done this before and may be able to guide me if possible. I have an app created and I have my Key. I cant even get the auth to work on their auth test page. I have found a couple of projects on github, but I have not been able to configure those to work either. Thanks for any advise.
Couple of screen shots.

 

[quarinteen]

What language are you using? I am having a problem even connecting but I may be able to help you.

 

[quarinteen]

Hello, I hope I can ask this here. I am attempting to create an app that connects to the developer api. I have created an app and it was approved. I have the API key, but when I attempt to test authentication via the test auth page at /authentication/apis/post/token-0 I get errors. The instructions at https://developer.tdameritrade.com/content/simple-auth-local-apps are not working for me either. Below are the values I am entering on the test auth page. Any advice or hints would be greatly appreciated.


grant_type = authorization_code
refresh_token == NULL or blank
access_type == Online
code = NULL or blank
client_id = [email protected]
redirect_uri = https://localhost

 

[trade_coder]

you will need to get the code first with following uri:
https://auth.tdameritrade.com/oauth...onse_type=code&redirect_uri=https://localhost

once u get the code from the response URI, extract the code value, then URLDecode it.
The decoded value will be to yr "code" property's value u pasted above.
Note that the "access_type" should be offline when getting the access and refresh tokens together.

Has anyone come up with a way to retrieve the complete charts data (including any studies loaded on the chart) from the ThinkorSwim in real-time? The goal is to be able to process the data again and generate signals using another scripting language (such as bash or python or powershell etc.) to overcome the limitations of the thinkscript.

TDAmeritrade does have an API, but it lacks in studies, range charts, tick charts, etc and also doesn't offer all time-frames supported by Thinkorswim.

I saw TOS databridge repo in github, but that also doesn't seem to support downloading the data from the currently loaded charts from what I understood.

Can you show a reference how you can request tick charts and studies in that API please?

 

[XeoNoX]

you can call TD and have them assist you to see if that is possible, from my understanding TD's tick chart is not really "true tick" from the way they receive their data from their data provider.

In addition to thinkScript, can Python be used in ThinkOrSwim?

No, but there may be a Python API... Thinkorswim is written in Java...
