// Module:  stdlib/finance/moving_average.tern
// Purpose: Ternary Moving Average Crossover
// Author:  RFI-IRFOS
// Ref:     https://ternlang.com

// A standard MA crossover strategy evaluated in trit space.

fn ma_crossover_trit(short_ma: float, long_ma: float, threshold: float) -> trit {
    let diff: float = short_ma - long_ma;
    
    // If the difference is negligible, return 'tend' (hold position)
    if diff > threshold { return affirm; } // Golden cross -> Buy
    if diff < -threshold { return reject; } // Death cross -> Sell
    return tend; // Flat market -> Hold
}

fn ema_trend_trit(current_price: float, ema: float) -> trit {
    // Exponential Moving Average trend detection
    if current_price > (ema * 1.01) { return affirm; } // Uptrend
    if current_price < (ema * 0.99) { return reject; } // Downtrend
    return tend; // Sideways
