Pullback Confluence (Trend + Structure + Price Action + Momentum)

Pullback Confluence Strategy - BUY CALL / SELL PUT (client 'Pullback Indicators' spec)\n\nSTRATEGY DESCRIPTION:\nReverse-engineered from the client's 'Pullback Indicators' TradingView suite (Pullback_Strategy_Document_v2). Stacks four layers - Trend, Structure (pivots), Price Action (candles), and Momentum - and only fires when all four agree (strict AND / Model A).\n\nSPEC STATUS - IMPORTANT:\nSeveral pieces of the client's original indicator are UNCONFIRMED from screenshots alone and are implemented here as clearly-labeled placeholders pending client sign-off: the momentum oscillator (real 4-line indicator is unknown; RSI(14) crossing back through 50 is used as a stand-in), the JMA trend filter (unavailable in this codebase; EMA9/EMA21 + SMA200 used instead), the pivot method (client's dropdown showed an unconfirmed 'New' method; Standard pivot formula used as placeholder), the TG1-TG16 target ladder (only TG1-TG4 implemented, pivot-level based per the client's own working hypothesis), and stop-loss/exit/risk management (NOT implemented - only a reference pullback-candle high/low is surfaced, not a final SL).\n\nCORE LOGIC (Step by Step):\n\nLAYER 1 - Trend: BULLISH if EMA9 > EMA21 (and close > SMA200 when available); BEARISH if EMA9 < EMA21 (and close < SMA200 when available)\n\nLAYER 2 - Structure / Pullback Zone: price within a configurable proximity (default 0.4%) of EMA21, OR of a same-side pivot level (S1-S4 for BUY, R1-R4 for SELL)\n\nLAYER 3 - Price Action Reversal Candle: BUY needs Hammer, Inverted Hammer, or Bullish Engulfing; SELL needs Shooting Star or Bearish Engulfing\n\nLAYER 4 - Momentum (placeholder): BUY needs RSI to have dipped below 50 recently and cross back >= 50; SELL needs RSI to have risen above 50 recently and cross back <= 50\n\nSIGNAL: all 4 layers agree -> PULLBACK_BUY_CALL / PULLBACK_SELL_PUT. A confluence_score (0-4) is also returned so the strict-AND requirement can be relaxed to a weighted model later without recoding.\n\nWHY THIS MATTERS:\n- Multi-layer confluence filters out low-quality single-indicator signals\n- Target ladder and pivot levels reuse the same standard pivot formula as the Phase 6 Support/Resistance scanners\n- Should be re-validated against real client trade data once Sections 3-8 of the spec are confirmed
