thertrader

This Shiny application is designed to help analysing trading strategies. It is an ongoing project that I improve when time allows. Feel free to get in touch should you have any suggestion.

*How to use the App as it is?
The App uses as input several csv files (one for each strategy). Each file has two columns: date and daily return. There is an example of such a file in the Github repository. The code is essentially made of 3 files.
-ui.R: controls the layout and appearance of the app
-server.R: contains the instructions needed to build the app. You can load as much strategies as you want as long as the corresponding csv file has the right format (see below).
-shinyStrategyGeneral.R: loads the required packages and launches the app
put ui.R and server.R file in a separate directory

In the server.R file change the inputPath, inputFile and keepColumns parameters to match your setting. The first two are self explanatory the third one is a list of column names within the csv file. Keep only date and daily return

I have managed to install this… and make it work. I implemented it for Facebook and Google, but you can extend it. My solution it is mostly as described in #116, with a bit of more code presented. The key aspects that lack in the #116 presentation (IMO) are:

• the registration as service of your custom FOSUBUserProvider (with the necessary parameters)
• set the service for oauth_user_provider in the security.yml with your custom created service

Here are the steps:

1. Routing. In routing.yml I have added all the routes for both bundles.
2. Configuration. I have set the config.yml mostly as it is presented in the HWIOAuthBundle.
3. Security. I have set the security.yml mostly as it is presented in the HWIOAuthBundle (though my routes are using /login pattern, not /connect). Also, the oauth_user_provider is set for my custom service.
