// 2. CALCULATIONS
// ==========================================

// --- A. CURRENT ASSET (The Stock) ---
// Calculate local volatility components
float vol_sma_sym = ta.sma(ta.tr, len_atr)
float vol_rma_sym = ta.rma(ta.tr, len_atr) // standard ATR

// Select local volatility
float vol_sym = calc_type == "Simple (SMA)" ? vol_sma_sym : vol_rma_sym

float chg_sym = close - close[1]
// Normalize: (Change / Volatility)
float norm_move_sym = nz(chg_sym / vol_sym)


// --- B. BENCHMARK (QQQ/SPY) ---
// Request all potential data at once to avoid conditional errors
[b_close, b_vol_sma, b_vol_rma] = request.security(sym_bench, timeframe.period, [close, ta.sma(ta.tr, len_atr), ta.rma(ta.tr, len_atr)])

// Select benchmark volatility AFTER the request
float b_vol = calc_type == "Simple (SMA)" ? b_vol_sma : b_vol_rma

float chg_bench = b_close - b_close[1]
// Normalize
float norm_move_bench = nz(chg_bench / b_vol)


// --- C. HIDDEN RELATIVE STRENGTH MATH ---
// Formula: Stock Normalized Move MINUS Market Normalized Move
float raw_rs = norm_move_sym - norm_move_bench

// Accumulate (The Line)
// FIXED MULTIPLIER (10x) applied internally for better Y-Axis scaling
float rs_line = ta.cum(raw_rs) * 10.0

// Signal
float rs_sig  = ta.sma(rs_line, len_sig)
