Tips On Getting Started In Python

Are Python compilers generally optimizing worser to assembly and running worse than C/C++ (mingw , gcc , visual studio x64 etc) or it depend also on ways of coding?

I have 2-3 years of programming experience and have gotten best multithreaded C++ performance on linux, gcc compiler.
On windows compilers all appear to perform almost equal to eachother with single thread.

As far as I know python is bit code that runs on a platform for pre-made c++ routines. Also know as an interpreter. This setup will always be slower than C++ since there is another layer to get to the machine code routines. C++ is the most direct unless you learn assembly.

If the resolution is smaller than than the ammount of data points no need to render all seperately.

By zooming do you mean smooth zooming?
Like zooming an image on smartphone or stepped zooming?
I have not yet seen any other libs support that way other than my own libs.

Very nice implementations there , have done similarly zoomale 2d libs via opengl that allow smooth stretching of datapoints and magnitude but not as refined and as many features as there. Only box chart and the other idk how to name chart type.

Hi,

Ive been a professional trader for about a decade but feel in order to keep with the times I really need to make the effort and start exploring the world of algo trading. Its benefits are clear.
Ive built "systems" on CQG and Tradestation in the past but want to use a more universal language. Knowing a few guys in the algo/fund world Python seems to be the way forward.

I was hoping to get your advice on best way to start. Im following the Codeacademy Python course and picking up the basics. But theres only so many times I can print "hello world" or change "parrot" from upper case to lower case. I still have no understanding how I can start applying this knowledge to trading. I really learn best in a way that is vocationally and solving a problem i am interested in.

So a couple of quick questions...

1/ how do you get your code into a trading environment? To take Tradestation for example, you write your code into a box and and it is being updated onto charts, giving you backtest results etc in real time almost. How does writing something on Idle or Notepad++ translate into complex charts? How does it translate basic code into charts and backtest results.

2/ CQG/Ninja Trader/Tradestation and other retail backtesting platforms have a trading vocabulary of keywords saved in its library such as "long, short, buy,sell, daily high" etc. Again, just writing in Idle or Notepad++ do you have to explain all these values to it?

I guess both these questions are "is there a trading environment to start coding into like CQG but instead of using its basic language it uses Python?"


All the YouTube vids/websites are so generic in their advice. Is there anywhere that specifically helps people to learn Python in a trading environment, forums/courses/software etc?

Any other tips on where to start?

Thanks

10. R Programming A-Z™: R For Data Science With Real Exercises!

No Starch Press publishes 4 good programming eBooks, 3 in Python and 1 in R. They are also having a sale but it ends Tomorrow Wednesday 11/23/2016 at 11:59 PM PDT (I think they meant PST). All of their eBooks are 50% off. Use code
PUMPKINPYTHON
1. Python Crash Course
2. Automate the Boring Stuff with Python
This book was written by the same person who did the above course with the same name.​

For anyone who is interested, No Starch Press is having a "Humble Book Bundle: Python Edition!" charity sale. You choose which bundle you want and how much you wish to give. There are 3 bundles and I believe you can get all 3 bundles for as little as $15. I believe you receive eBooks in the form of PDF, ePUB and MOBI formats. You do not receive printed books.

These 3 look good:
1. Python Crash Course
2. Doing Math with Python
3. Automate the Boring Stuff with Python
There is a corresponding Udemy course by the same author.

4. Invent Your Own Computer Games with Python, 4th Edition
5. Teach Your Kids to Code.
There is a corresponding Udemy course by the same author.


No Starch Press also has Book of R but they did not include it in their bundles.
