Market Pulse - Dual Signal Comparison
10 Stocks: AAPL, MSFT, AMZN, NVDA, TSLA, META, GOOGL, JPM, XOM, SPY

Data date: . Compute Signal is Return/Vol for the latest 5-minute bar on this day.

Formulas & data source

Compute Signal (per 5โ€‘minute bar):

Return = (Close โˆ’ Open) / Open Vol = Std(Return over last 20 bars) + 1eโˆ’4 Signal = Return / Vol

Learning Signal:

Ridge regression trained on the last ~300 Compute Signal records (across the last 7 days). Features include returns, vol, rolling stats, and lagged compute signals (previous 1โ€“2 bars) so the model can follow the compute trend. The model predicts the current signal; it runs hourly (Lambda) and persists to learning-models/{ticker}/latest.pkl. When there isnโ€™t enough new data, the last saved model is used (LOADED_PREVIOUS).

Parameter Explanations

Model: Choose the AI model that best fits your needs. Each model has different strengths and capabilities.
Temperature: Controls randomness in responses. Lower values (0.1-0.3) make responses more focused and deterministic. Higher values (0.7-1.0) make responses more creative and varied. Range: 0.0 to 2.0.
Max Tokens: Limits the length of the AI response. Higher values allow longer, more detailed responses. Lower values create shorter, more concise answers. Range: 100 to 4000 tokens.

Rolling Metrics Benchmark

Compare Naive OOP vs Rolling Deque vs SoA on synthetic tick stream (VWAP, vol, rolling max/min).

How the 3 implementations are evaluated

Concepts used to evaluate each implementation:

  • โœ… Streaming computation โ€” Each tick is processed once as it arrives; no full replay. All three impls consume the same stream via on_tick(ts, price, size).
  • โœ… Sliding window โ€” Metrics are over the last W seconds only. Naive keeps a list and evicts by time; Deque and SoA use time-bounded deques so the window slides in O(1) per eviction.
  • โœ… Amortized complexity โ€” Naive: O(W) per tick (rescan). Deque & SoA: O(1) amortized (incremental update + monotonic deque for max/min).
  • โœ… Cache-friendly design โ€” Naive: list of objects (more indirection). SoA: deques of primitives (ts, price, size separate), better locality and fewer allocations.
  • โœ… Incremental state โ€” Deque and SoA maintain running sums (e.g. sum(priceร—size), sum(size)) and rolling variance state; on eviction they subtract. Naive recomputes from the window each time.

The benchmark measures throughput (ticks/sec), latency (ms/tick), and peak memory under the same stream and window; correctness is checked by comparing VWAP, vol, and rolling max/min across all three.
