// TradingView Pine Script strategy for Smart Money Concept (SMC)
//@version=5
strategy("Smart Money Concept Strategy", overlay=true, default_qty_type=strategy.fixed, default_qty_value=100)

// === Input Parameters ===
input_risk_percentage = input.float(1, title="Risk Percentage", step=0.1)
input_atr_length = input.int(14, title="ATR Length")
input_ema_short = input.int(50, title="EMA Short")
input_ema_long = input.int(200, title="EMA Long")

// === Calculations ===
atr = ta.atr(input_atr_length)
ema_short = ta.ema(close, input_ema_short)
ema_long = ta.ema(close, input_ema_long)

// === Utility Functions ===
// Identify Order Blocks
is_order_block(price, direction) =>
    ((high[1] > high[2] and low[1] > low[2] and direction == 1) or (high[1] < high[2] and low[1] < low[2] and direction == -1))

// Identify Imbalance Zones
is_imbalance() =>
    range_high = high[1]
    range_low = low[1]
    range_high > close and range_low < close

// Calculate Lot Size Based on Risk
calculate_lot_size(stop_loss_points, account_balance) =>
    risk_amount = account_balance * (input_risk_percentage / 100)
    lot_size = risk_amount / (stop_loss_points * syminfo.pointvalue)
    lot_size

// Determine if Market is Consolidating
is_consolidating() =>
    (ta.highest(high, 20) - ta.lowest(low, 20)) / atr < 2

// === Visual Enhancements ===
// Plot Order Blocks
// if is_order_block(close, 1)
//     line.new(x1=bar_index[1], y1=low[1], x2=bar_index, y2=low[1], color=color.green, width=2, extend=extend.right)
// if is_order_block(close, -1)
//     line.new(x1=bar_index[1], y1=high[1], x2=bar_index, y2=high[1], color=color.red, width=2, extend=extend.right)

// Highlight Imbalance Zones
// if is_imbalance()
//     box.new(left=bar_index[1], top=high[1], right=bar_index, bottom=low[1], bgcolor=color.new(color.orange, 80))

// === Logic for Trend Confirmation ===
is_bullish_trend = ema_short > ema_long
is_bearish_trend = ema_short < ema_long

// === Entry Logic ===

        stop_loss_points = math.abs(close - stop_loss) / syminfo.pointvalue
        lot_size = calculate_lot_size(stop_loss_points, account_balance)
