Actual emulator captures. Synthetic data.

  • Standalone offline Rust CPU engine; calculations compared on PC and Android using the same data.
  • EMA 6, 12 or 24 and three fee settings, on 240 synthetic 1-hour bars. Cash when the entry signal ends.
  • Buy & Hold comparison with the same starting window and fees; measured fee impact and trade replay.
  • Interactive 3 × 3 sensitivity matrix: nine sequential native calculations, compared by net return, drawdown and difference from Buy & Hold. Explore cash and positions bar by bar.
  • Three comparison bars show the strategy, Buy & Hold and interest-free cash on one scale. Inspect the decline from each capital peak in the replay.
  • The last two experiments stay on your device. Compare changed settings, capital and drawdown; changing both settings is not a one-variable experiment. A bounded workshop, not a general Pine importer.

Time Machine

Build your team. Understand its tradeoffs.

Time Machine - actual Android emulator capture 1Time Machine - actual Android emulator capture 2

Actual emulator captures. Synthetic data.

  • 3 synthetic missions, each with 240 bars.
  • Select 2 of 3 rule-based profiles plus cash; the initial allocation stays fixed.
  • 4 reveal chapters with interactive replay: inspect capital, cash and exposure at each revealed bar.
  • Jump to recorded entries and exits. The debrief separates absolute return, performance against the reference, drawdown budget and time spent in cash.
  • Positive and negative contribution bars show what each profile added or lost. Activity details distinguish closed trades, time in position and idle capital.
  • Compare another cash allocation without changing the original: capital, drawdown and their tradeoffs are measured separately. Compatible saved results survive interface-only app updates.

Tested scope, clear limits

Android 8.0+ (API 26). Both APKs are debug-signed prototypes. Tested on an x86_64 Android emulator, API 35. ARM64 builds exist, but have not been verified on a physical phone. Compatibility with your device is not guaranteed.

Both apps work without an account, Internet permission or billing. Simulations use synthetic data and fixed rules, not real AI or live market feeds. No broker connection or real orders. Educational prototypes, not financial advice or return promises.

Before installing an APK

Install only if you trust Strategy Arena and the source of this file. Android may warn that the app comes from outside the Play Store and request installation permission for the browser or file manager opening it. This is not a Play Store release or a safety certification.

Keep Play Protect enabled. If Android blocks the app or flags it as harmful, stop and report it; do not bypass the protection. You can revoke the browser or file manager's installation permission afterwards.
