Is it possible to install and use QChartist on an outdated operating system?


Sweet and delicious deep-fried Oreos

While QChartist is primarily used for financial market analysis, have any users experimented with applying its forecasting capabilities to non-traditional quantifiable data, such as weather patterns, social media trends, or even sports statistics? If so, what were the results and challenges faced during the implementation process?

- Improved trading system and updated in documentations
- In the Watchlist Free, Yahoo Finance is no longer supported since they changed their web page
- The chat works again, i put a valid user agent for curl and underscores for spaces and problem solved
- Unlock get chart button works also for geckoterminal data source
- Added the TradingView to MT4 csv converter v103 zip file in the docs folder

Highlighted Pros of QChartist

1. Faster Indicator Loading: Since all computations are processed directly by the CPU, QChartist is significantly faster for loading and analyzing indicators, especially on local machines.
   
2. Flexibility and Customization: The open-source nature of QChartist provides unparalleled flexibility, allowing users to modify, extend, or integrate it as per their requirements.
   
3. Cost-Effectiveness: Being free and open-source, QChartist is an attractive option for cost-conscious users.
   
4. Offline Usability: Unlike TradingView, QChartist does not require an internet connection, making it reliable for users with limited or no access to online resources.
   
5. High Performance: Local processing ensures consistent performance, unaffected by server downtime or internet lag.
   

• Choose QChartist: If you prioritize speed, customization, offline access, or open-source projects.
  
• Choose TradingView: If you value cloud accessibility, a large community, and integration with market data sources.
  

Unfortunately Yahoo Finance changed their remote web page for the watchlist so that it is no longer possible to get all tickers data with curl.
Thus the watchlist free is no longer functional with Yahoo for the moment.

Possible workaround : use python Selenium WebDriver to get the web page but its complicate to make it portable and to use it successfully with WineHQ (wine has only internet explorer by default and it bugs with the window handle)

For the momebt i am still looking for a portable headless browser that is compatible with WineHQ, this would rescue the watchlist functionality.

Tiingo Crypto still works with the watchlist free but is limited to 50 tickers max in the list which is not very satisfactory.

I am currently trying to find leads for a functional and non limited free watchlist.


Alternatively for the moment you can use a watchlist outside qchartist software, for example:
- open the yahoo watchlist url in your web browser https://finance.yahoo.com/quotes/GC=F,CL=F/view/v1 and change the url with your tickers
- use your broker's integrated watchlist
- coinmarketcap
- tradingview
 etc. many alternate solutions are possible

Sorry for the inconveignance.

Time and work will tell if a solution is possible for a usable integrated watchlist in qchartist. I work on that.

In QChartist build 306:

- Added 2 new indicators : Chandle momentum and Williams %R oscillators

- Added the python 3.8 compiler and an L-System fractals on chart module for experimental purposes (fractals drawing tool).
Yes, you can use python language with QChartist and you may even call it using C++ directly.

- Problem with indicators description order with the "?" button in the indicators list solved (description in indicators .ini files)

- You can sort the Watchlist Free tickers by their name or 24h percent change
- Also for the Watchlist Free you can use Yahoo Finance or Tiingo Data Sources (need a Tiingo API key for Tiingo)
- For the Watchlist Free you can browse Yahoo Finance tickers for more info on symbols with the info button

- Added some Crypto web portals in the Data Source Crypto DEX button

- Correct Julian Dates are now displayed when you move the mouse over the chart

- Modified docs\trading_system.zip + chm sh5 and pdf

The square root spiral or Einstein spiral or Pythagorean spiral is a spiral composed of continuous right triangles whose hypotenuses are square roots of natural numbers. It was first constructed by Theodorus of Cyrene.

Let’s see how to construct this spiral: https://heymathblogcom.wordpress.com/201...ot-spiral/

Google for "prime fractal spiral polar" https://youtuberead.com/why-do-prime-numbers-make : done but experimental
Equation of time http://time-price-research-astrofin.blog...-2012.html
Fityk software and Pearson7
Various methods of spline interpolation : https://codes-sources.commentcamarche.ne...ion-spline
https://www.qchartist.net/files/programm...__Page.zip

It can be useful to be able to sort the watchlist tickers by ticker name or by 24 hours percent change.
I have already coded the trick and it will be available in the build 306.
Being able to save and create/open new lists of tickers would be nice.

Also the new 2 indicators oscillators Chandle Mom and Williams WPR will be added in build 306.

I also intend to add the python 3.8 compiler and to code an L-System fractals on chart module for experimental purposes.

There is also a bug to solve with indicators descriptions in ini files which are not correctly displayed with the "?" button.

Adding multiple separate indicator canvas would be good.

Editing indicators on chart with the mouse button would be good also.

I find these 2 oscillators Chandes Momentum and Williams %R interesting that's why i ported them.
 
Will add these indicators in the official release later.
 
For the moment you can download the indicators attached in the post 

  oscillators.zip (Size: 5.22 KB / Downloads: 0)
and copy/paste them in the indicators folder, also
 
add in includes/cppincludes.cpp
 
// ''RQEXPORT function williams_percent_r(periodstr,curtfstr)
#include "indicators\williams_percent_r.cpp"

// ''RQEXPORT function chandes_mom(periodstr,curtfstr)
#include "indicators\chandes_mom.cpp"
 
(before the line #include "includes\getbufferdata.cpp")
 
and
 
add in includes/getbufferdata.cpp
 
if (strcmp(buffernamee,"williams_percent_rbuffer")==0) { sprintf(convbuf,"%f",williams_percent_rbuffer[atoi(offsett)]);return convbuf; }
if (strcmp(buffernamee,"chandes_mombuffer")==0) { sprintf(convbuf,"%f",chandes_mombuffer[atoi(offsett)]);return convbuf; }
 
recompile
 
enjoy
