Core scope
• 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.
