// 1. Custom main indicator: OHLC mean channel
// ============================================
plotMain({
    id: 'ohlc_mean',
    calculator: (idx, open, high, low, close, volume) => {
        return (high + low + close) / 3;
    },
    options: {
        name: 'OHLC Mean',
        color: '#FF6B6B',
        width: 2,
        style: 'solid'
    }
});

// 2. Another main indicator: Price volatility (High - Low)
plotMain({
    id: 'volatility',
    calculator: (idx, open, high, low, close, volume) => {
        return high - low;
    },
    options: {
        name: 'Volatility',
        color: '#4ECDC4',
        width: 1,
        style: 'dashed'
    }
});

// 3. Batch add main indicators - multiple lines
plotMain([
    {
        id: 'upper_band',
        calculator: (idx, open, high, low, close, volume) => {
            return close * 1.05;
        },
        options: { name: 'Upper Band', color: '#45B7D1', width: 1, style: 'dotted' }
    },
    {
        id: 'lower_band',
        calculator: (idx, open, high, low, close, volume) => {
            return close * 0.95;
        },
        options: { name: 'Lower Band', color: '#F39C12', width: 1, style: 'dotted' }
    }
]);

// 4. Custom sub indicator: RSI style
plotSub({
    id: 'custom_rsi',
    calculator: (idx, open, high, low, close, volume) => {
        return 50 + Math.sin(idx * 0.1) * 30;
    },
    options: {
        name: 'Custom RSI',
        color: '#FF6B6B',
        width: 2,
        type: 'line'
    }
});

// 5. Custom sub indicator: Volume histogram
plotSub({
    id: 'custom_volume',
    calculator: (idx, open, high, low, close, volume) => {
        return volume / 1000;
    },
    options: {
        name: 'Volume/1000',
        color: '#4ECDC4',
        type: 'histogram'
    }
});

// 6. Batch add sub indicators
plotSub([
    {
        id: 'momentum',
        calculator: (idx, open, high, low, close, volume) => {
            return close - open;
        },
        options: { name: 'Momentum', color: '#FF9800', type: 'line', width: 1 }
    },
    {
        id: 'range_percent',
        calculator: (idx, open, high, low, close, volume) => {
            return ((high - low) / close) * 100;
        },
        options: { name: 'Range%', color: '#9C27B0', type: 'area' }
    }
]);

console.log("All custom indicators added");
console.log("Main indicators: OHLC Mean, Volatility, Upper/Lower Bands");
console.log("Sub indicators: Custom RSI, Volume, Momentum, Range %");

return {
    message: "Custom indicators test completed",
    mainCount: 5,
    subCount: 5
};
