Sigmoid Cycle Intraday Suite

Family: hybrid · Regime: trending · Complexity: medium · Asset classes: Equities, Forex · Timeframes: 15M

Thesis

Market momentum follows a non-linear S-curve (Sigmoid). Price exhibits a 'sweet spot' of acceleration between initial breakout and terminal exhaustion. By isolating this phase using a Sigmoid regime filter and confirming it with Ehlers' detrended cycles, we enter during high-velocity transitions. The Oracle Probes provide the structural trigger, while RMSE ensures we stay out during periods of high 'noise' where the price deviates excessively from its local mean.

Components

• Logistic Function (SIGMOID) (regime) — Filters for the 'sweet spot' of momentum; avoids entering when the market is overextended (saturated at 0 or 1) or lacks sufficient acceleration.
• TopTrend (BBands Stop) (direction) — Provides the primary trend bias based on volatility bands, ensuring entries align with the mid-term volatility structure.
• Oracle Probes 15M Intraday Suite (entry) — Provides tactical execution via VWMA crossovers and candlestick patterns within the context of the 5-day moving average.
• Zero Lag Least Squares Moving Average (ZLSMA) (exit) — Acts as a fast-reacting exit trigger that minimizes lag, allowing the strategy to capture the meat of a move before a reversal.
• Root Mean Squared Error (RMSE) (risk) — Quantifies current volatility 'noise' to set dynamic stop losses and normalize position sizing.
• Ehlers Detrended Synthetic Price (DSP) (confirmation) — Ensures the entry is timed with the cyclic component of price, avoiding entries at local cycle peaks/troughs.

Known failure conditions

• Persistent saturation of the Sigmoid function (staying at >0.95 or <0.05) indicating a parabolic move where this mean-reversion/cycle hybrid fails.
• RMSE spikes without price movement (implied volatility expansion without direction).
• The 'Zebra Parity' logic in Oracle Probes creates arbitrary day-of-week biases that decouple from market reality.
