策略名稱： 基於 DI+ 和 DI- 的趨勢追蹤策略 (附 ATR 止損止盈) / DI+ and DI- Trend Following Strategy with ATR Stop Loss and Take Profit

策略描述 (中文)：

本策略基於趨向指標 (Directional Movement Index, DMI) 中的 DI+ 和 DI- 指標，結合趨勢過濾均線和 ATR (Average True Range) 指標來判斷市場趨勢和設定動態的止損止盈。DMI 旨在衡量價格變動的方向和強度。

DI+ (正趨向指標)： 衡量向上趨勢的強度。
DI- (負趨向指標)： 衡量向下趨勢的強度。
當 DI+ 高於 DI- 且收盤價高於趨勢過濾均線時，視為強勢上漲趨勢，產生買入訊號；反之，當 DI- 高於 DI+ 且收盤價低於趨勢過濾均線時，視為強勢下跌趨勢，產生賣出訊號。

本策略使用 ATR 指標來計算動態的止損和止盈水平，使止損止盈的距離能根據市場的波動性進行調整，提高策略的適應性。

策略描述 (英文)：

This strategy is based on the Directional Movement Index (DMI), specifically the DI+ and DI- indicators, combined with a trend-filtering moving average and the Average True Range (ATR) to identify market trends and set dynamic stop-loss and take-profit levels. The DMI is designed to measure the direction and strength of price movements.

DI+ (Positive Directional Indicator): Measures the strength of upward trends.
DI- (Negative Directional Indicator): Measures the strength of downward trends.
When DI+ is above DI- and the closing price is above the trend-filtering moving average, it is considered a strong uptrend, generating a buy signal. Conversely, when DI- is above DI+ and the closing price is below the trend-filtering moving average, it is considered a strong downtrend, generating a sell signal.

This strategy uses the ATR indicator to calculate dynamic stop-loss and take-profit levels, allowing the stop-loss and take-profit distances to adjust to market volatility, improving the strategy's adaptability.

策略參數 (中英文對照)：

DI 長度 (DI Length): 計算 DI+ 和 DI- 的週期長度。 (預設值: 14) / The period length for calculating DI+ and DI-. (Default: 14)
ADX 平滑 (ADX Smoothing): 用於平滑 ADX 的週期長度 (即使不直接使用 ADX，此參數也是必需的)。 (預設值: 14) / The period length used for smoothing the ADX (this parameter is required even if ADX is not used directly). (Default: 14)
趨勢過濾均線長度 (Trend Filter Moving Average Length): 計算趨勢過濾均線的週期長度。 (預設值: 20) / The period length for calculating the trend-filtering moving average. (Default: 20)
趨勢強度門檻值 (Trend Strength Threshold): DI+ 和 DI- 之間差距的門檻值，用於判斷趨勢是否足夠強勁。 (預設值: 20) / The threshold for the difference between DI+ and DI-, used to determine if the trend is strong enough. (Default: 20)
ATR 長度 (ATR Length): 計算 ATR 的週期長度。 (預設值: 14) / The period length for calculating the ATR. (Default: 14)
ATR 停損倍數 (ATR Stop Loss Multiplier): 止損價格與進場價格之間以 ATR 的倍數表示的距離。 (預設值: 1.5) / The distance between the stop-loss price and the entry price, expressed as a multiple of the ATR. (Default: 1.5)
ATR 止盈倍數 (ATR Take Profit Multiplier): 止盈價格與進場價格之間以 ATR 的倍數表示的距離。 (預設值: 2.5) / The distance between the take-profit price and the entry price, expressed as a multiple of the ATR. (Default: 2.5)

訊號判斷 (中英文對照)：

買入訊號 (Long Entry Signal): DI+ > DI- + 趨勢強度門檻值 且 收盤價 > 趨勢過濾均線 / DI+ > DI- + Trend Strength Threshold AND Close > Trend Filter Moving Average
賣出訊號 (Short Entry Signal): DI- > DI+ + 趨勢強度門檻值 且 收盤價 < 趨勢過濾均線 / DI- > DI+ + Trend Strength Threshold AND Close < Trend Filter Moving Average
止損止盈計算 (中英文對照)：

多單停損 (Long Stop Loss): 進場價格 - (ATR * ATR 停損倍數) / Entry Price - (ATR * ATR Stop Loss Multiplier)
多單止盈 (Long Take Profit): 進場價格 + (ATR * ATR 止盈倍數) / Entry Price + (ATR * ATR Take Profit Multiplier)
空單停損 (Short Stop Loss): 進場價格 + (ATR * ATR 停損倍數) / Entry Price + (ATR * ATR Stop Loss Multiplier)
空單止盈 (Short Take Profit): 進場價格 - (ATR * ATR 止盈倍數) / Entry Price - (ATR * ATR Take Profit Multiplier)
