// Fakeout-Confirmed Strategy — 4 Filter Layers

// TradingView: https://tr.tradingview.com/u/trugurpala/
//
// TR: Dört yapılandırılabilir fakeout filtresi kullanan sinyal stratejisi.
// EN: Signal strategy with four configurable fakeout filters.
// Önerilen TF: 15M, 1H, 4H

// LESSONS_LEARNED kontrol listesi:
// ✅ alertcondition() yok → alert() kullanıldı
// ✅ calc_on_every_tick yok: bar-close calculation setting; fill, data, and cost assumptions remain.
// ✅ barstate.isconfirmed + table → uyarısız, kapanmış barda güncellenir
// ✅ Çok satırlı "and" yok → tek satır
// ✅ [1] + lookahead_on is a confirmed HTF pattern only when the requested timeframe is higher than the chart; this code does not enforce that relation.
