Buy portfolio home widget - Trace your stock holding without launching app

Sometimes, users would like to check how "rich" they are, without even launching the stock market app.

We decide to build a home widget for buy portfolio. User may have a quick info on her net worth, by looking at the phone screen.

We optimize heavily, to ensure buy portfolio home widget only consume minimal battery life, yet is reasonable fast enough.

We hope that you will find it useful to your stock investment journey.

Upcoming development plans for June and onward

Although we have 3 releases in May, the development progress is some how sluggish. Here's what I wish to accomplish in next coming months.

Support both Yahoo! and Google Finance
Currently, only India is using Google Finance data feed. There's technical barrier which holds us to make Google Finance work for other countries.

Our core stock engine is RealTimeStockMonitor. If our watchlist contains both United States (assume Google Finance is picked for United States) and Malaysia (assume Yahoo Finance is picked for Malaysia) stocks, JStock won't work. RealTimeStockMonitor only able to support single country stock server factory, not multiple countries stock server factories.

Re-architecture the entire RealTimeStockMonitor to support multiple countries stock server factories is essential

Displays multiple countries watchlist in single page
Ability to display both United State stocks & Malaysia stocks in single page.

Launch chart and news info from portfolio page directly

Previously, if we were in portfolio page, in order to launch chart and news info page, we need to switch back to watchlist page. In upcoming release, we are going to add an info button in detailed buy/sell info page. 

With such newly added button, you may launch chart and news info page, without having to leave portfolio page.

New notification UI for JStock Android's background alert feature

This feature will be available in next few days. Stay tune
