// -----------------------------------------------------
// Multi-Signal Conservative Strategy (Pine Script v5)
// + More ICT Concepts (HTF Bias, FVG, Killzone, BOS)
// -----------------------------------------------------
//
// Combines:
// - RSI, Stochastic, MACD, 200 EMA (lower TF)
// - Higher Timeframe (HTF) bias check via 200 EMA
// - Kill Zone time filter
// - Fair Value Gap (FVG) detection (simplified 3-candle approach)
// - Break of Structure (BOS) using pivot highs/lows
// - Only trade markers on chart (no extra indicator plots).
//
// Use on lower timeframes: 1m to 15m
// Always backtest thoroughly and manage risk properly.

// -----------------------------------------------------
// 1) Higher Timeframe Bias
// -----------------------------------------------------
//
// We'll request the HTF close, then compute the HTF EMA on that data
// to decide if it's bullish or bearish overall.

htfClose       = request.security(syminfo.tickerid, htfTimeframe, close)
htfEma         = request.security(syminfo.tickerid, htfTimeframe, ta.ema(close, htfEmaLen))

isBearHTF      = htfClose < htfEma

// -----------------------------------------------------
// 2) Kill Zone / Session Filter
// -----------------------------------------------------
//
// We'll only consider trades if the current bar is within
// the user-defined session time (e.g., 07:00 to 10:00 local or exchange time).

isInKillZone = time(timeframe.period, sessionInput) != 0

// -----------------------------------------------------
// 3) Fair Value Gap (FVG) Detection (Simplified)
//
// For a "Bullish FVG" among bars [2], [1], [0]:
//     high[2] < low[0] => there's a gap that bar [1] didn't fill
// For a "Bearish FVG":
//     low[2] > high[0] => there's a gap that bar [1] didn't fill
//
// Real ICT usage might check partial fill, candle bodies vs wicks, etc.
// This is just a minimal example for demonstration.

fvgBarsAgo = fvgLookbackBars // default = 2
bullFVG = high[fvgBarsAgo] < low  // e.g. high[2] < low[0]
bearFVG = low[fvgBarsAgo]  > high // e.g. low[2]  > high[0]

// -----------------------------------------------------
// 4) Break of Structure (BOS)
// -----------------------------------------------------
// Using pivot detection from previous example:

swingLen = 2  // pivot detection length (bars on each side)
// Identify a pivot high at bar [1]
swingHigh = high[1] > high[2] and high[1] > high[0]
// Identify a pivot low at bar [1]
swingLow  = low[1]  < low[2]  and low[1]  < low[0]

// Track the most recent pivot high & low
var float lastPivotHigh = na
var float lastPivotLow  = na

if swingHigh
    lastPivotHigh := high[1]

if swingLow
    lastPivotLow := low[1]

bosUp   = not na(lastPivotHigh) and (close > lastPivotHigh)
bosDown = not na(lastPivotLow)  and (close < lastPivotLow)
