// 1. Configuration and Weight Optimization Parameters
//────────────────────────────────────────────────────────────────────────────
// Weights can be optimized to favor dimensions with higher historical correlation.
// Base values are maintained but can be fine-tuned.
w_technical   = input.float(0.4,   "Technical Weight",        step=0.05)
w_emotional   = input.float(0.2,   "Emotional Weight",      step=0.05)

// Smoothing period and bandwidth affect the "memory" and sensitivity of the signal.
smooth_length = input.int(20, "Smoothing Period", minval=5)
bw_param      = input.float(20, "Bandwidth", minval=1, step=1)

//────────────────────────────────────────────────────────────────────────────
// 2. Risk Management Parameters
//────────────────────────────────────────────────────────────────────────────
// Incorporate stop-loss and take-profit in percentage to protect capital.
// These parameters can be optimized through historical testing.
stopLossPerc   = input.float(1.5, "Stop Loss (%)", step=0.1) / 100   // 1.5% stop-loss
takeProfitPerc = input.float(3.0, "Take Profit (%)", step=0.1) / 100   // 3.0% take-profit

//────────────────────────────────────────────────────────────────────────────
// 3. Additional Filters (Trend and Momentum)
//────────────────────────────────────────────────────────────────────────────
// A long-term moving average is used to confirm the overall trend direction.
trend_length = input.int(200, "Trend MA Period", minval=50)
// RSI is used to confirm momentum. A level of 50 is common to distinguish bullish and bearish phases.

//────────────────────────────────────────────────────────────────────────────
// 5. Nadaraya-Watson Smoothing Function
//────────────────────────────────────────────────────────────────────────────
// This function smooths each dimension using a Gaussian kernel.
// Proper smoothing reduces noise and helps obtain a more robust signal.

// 7. Integration of Dimensions
//────────────────────────────────────────────────────────────────────────────
// The integrated signal is composed of the weighted sum of each smoothed dimension.
// This multidimensional approach seeks to capture different aspects of market behavior.

sma_integrated = ta.sma(integrated_signal, 10)

//────────────────────────────────────────────────────────────────────────────
// 8. Additional Filters to Improve Accuracy and Win Rate
//────────────────────────────────────────────────────────────────────────────
// Trend filter: only trade in the direction of the overall trend, determined by a 200-period SMA.
trendMA = ta.sma(close, trend_length)
// Momentum filter: RSI is used to confirm the strength of the movement (RSI > 50 for long and RSI < 50 for short).
rsi_val = ta.rsi(close, 14)

// Crossover signals of the integrated signal with its SMA reference.

// Incorporate trend and momentum filters to filter false signals.
longSignal  = rawLongSignal and longFilter

//────────────────────────────────────────────────────────────────────────────
// 9. Risk Management and Order Generation
//────────────────────────────────────────────────────────────────────────────
// Entries are made based on the filtered integrated signal.
