Slope Failure (Momentum Stall) STRATEGY

//======================================================================================
// SLOPE FAILURE (MOMENTUM STALL) STRATEGY
//--------------------------------------------------------------------------------------
// WHAT THIS STRATEGY DOES
// -----------------------
// This strategy trades **momentum failure**, not trend direction.
//
// Instead of predicting where price will go, it detects when **momentum can no longer
// continue in its current direction** and briefly fades that failure.
//
// Core idea:
// - Momentum expands → slope grows
// - Momentum stalls → slope collapses or flips
// - That stall represents **state transition**, not noise
//
// The system exploits these transitions repeatedly at short horizons.
//
//--------------------------------------------------------------------------------------
// HOW MOMENTUM IS MEASURED
// ------------------------
// 1. Source price (optionally smoothed)
// 2. First derivative (slope = price[t] - price[t-1])
// 3. Optional smoothing of the slope itself
//
// The slope represents **instantaneous directional force**, not trend bias.
//
//--------------------------------------------------------------------------------------
// ENTRY LOGIC (SLOPE FAILURE)
// ---------------------------
// • Bull Slope Failure (SHORT):
// - Prior slope was sufficiently positive
// - Current slope collapses to zero or below
// → Upward momentum failed → enter SHORT
//
// • Bear Slope Failure (LONG):
// - Prior slope was sufficiently negative
// - Current slope rises to zero or above
// → Downward momentum failed → enter LONG
//
// Optional:
// - Minimum slope band can be enforced to avoid weak/noisy failures
//
//--------------------------------------------------------------------------------------
// EXIT LOGIC
// ----------
// Primary exits are **force-based**, not price-based:
//
// • Longest Slope Local Turn (optional):
// - Detects when the strongest slope in a recent window has occurred
// - Exits when momentum starts decaying from that extreme
//
// • Percent Stop Loss (optional):
// - Fixed % protection relative to entry price
//
// The strategy does NOT rely on profit targets.
// Winners are exited when **momentum decays**, not when price "looks good".
//
//--------------------------------------------------------------------------------------
// POSITION SIZING
// ---------------
// This strategy supports **percent-of-equity sizing**, computed dynamically:
//
// position size = (account equity × % allocation) / price
//
// This allows:
// - P&L to scale smoothly
// - Drawdowns to remain proportional
// - The same logic to work across symbols and account sizes
//
//--------------------------------------------------------------------------------------
// STRATEGY CHARACTERISTICS
// ------------------------
// • High trade count
// • Win rate near ~45–50%
// • Small, fast losers
// • Slightly larger winners
// • Very low drawdown
//
// This profile is intentionally designed for **scalability**, not prediction.
//
//--------------------------------------------------------------------------------------
// IMPORTANT NOTES
// ---------------
// • This is NOT a trend-following strategy
// • This is NOT a mean-reversion guess
// • This is a momentum **state-transition detector**
//
// The edge comes from structure + exits + sizing — not indicators.
