Android Option Chain Analysis App -- 2
Budget: ₹600 – ₹1,500 INR
I need an Android application that lets me study option chains with live market feeds while staying logged in to my Indian brokerage accounts (NSE, BSE, MCX).
I need a clean, fast Android application that lets traders view and interpret option chains on the go. The core of the job is to stream real-time market data, draw smooth interactive charts, and trigger configurable alerts and notifications whenever preset conditions hit. Authentication will be a straightforward e-mail-and-password flow; no social or biometric login is required.
Data must auto refresh instantly without forcing the user to reload the screen, so a well-structured brocker live-feed solution is essential. I also want pinch-zoom, cross-hair, and tap-to-inspect interactions inside the option chain and chart views so a user can drill into individual strikes and expiries with minimal latency.
For alerts, the user should be able to set simple rules—price crosses, IV thresholds, open-interest spikes—and receive both in-app and push notifications. Please design your codebase with future brokerage API integration in mind; a clean MVVM or similar architecture in Kotlin (or modern, well-structured Java) is preferred.
Core scope
app deploy app store [ i pay app storeb fee ]
data feed = brocker
• Real-time data: the screen must refresh automatically matching BROKER ticks
• Option-chain visualisation: calls, puts, LTP,CHANGE PRICE AND PURCETEGE , OI, CHANG IN OI, DEGRANCE IN OI, VOL OI, CHANGE IN VOLUME OI , DEFRANCE OF VOLUME , VIX, BUILDUP, SUPORT, RASISTANCE, IV, greeks and strike ladders should be displayed in an intuitive grid; I want to tap any strike to open a detail panel. or chart
• Broker connectivity: a single sign-on flow for the three exchanges above so I can view positions in the same dashboard (trade execution is not needed for this phase).
Tech expectations
Please build in Android Studio with Kotlin or Java, using a clean MVVM/MVI architecture and SQLite/Room (or Realm) for caching. Charts or tables can rely on open-source libraries such as MPAndroidChart as long as licences are respected. Source code and a signed APK are required; configuration keys must be abstracted into a .properties file so I can point the build at my own data vendor later.
Acceptance criteria
1. Live data lag ≤ 15 ms second during market hours on a 50 Mbps network.
2. Option-chain grid renders, scrolls, and filters without dropped frames on a mid-range Android 7 + device.
3. Successful login and data pull from all three exchanges behind a single credentials screen.
4. Code compiles cleanly, includes README setup notes, and passes a lint check.
