Build an application that shows candle charts

Read the instructions carefully all the way to the end. I need an application that displays candle charts as well as some drawing on top of it, like lines, squares, ... etc. All the data will be provided via web APIs, returning JSON. The application can be done in iOS, Android or Windows, it does not matter since eventually all platforms will be required. Push notifications will be required as well, so this is important in order to properly chose the platform. While mobile platforms are encouraged, considering the amount of data, the screen size will be allowed only in tablets, laptops and/or desktops. If interested, you need to be willing to do a simple demo, that makes one web API call that I will provide you and it will display a simple candle chart with two lines. You are totally free in deciding how to show the candle chart and what data to use for the lines, again, this is just a demo to show that you have the skills to do the job. You can put watermarks if you want to, no code is required, screenshots or executable files is OK since of course, this is not the end job. To the participants that show a proper demo (just to show that you can do chartings and know how to read JSON via web API), the full list of requirements will be given so they can properly bid in time and money. While the initial project is very small and easy; there is a lot to do in future versions, so bid wisely since this could be a long project with many future iterations. If interested, please say exactly these words "I can do charts" in your response, there are a lot of bots out there and people that do not read instructions, I am trying to avoid both. Only if you put "I can do charts" in your response you will be considered. Happy bidding!
