This script is an implementation of the **Directional Movement System (DMS)**, which includes the **Positive Directional Indicator (+DI)**, **Negative Directional Indicator (-DI)**, and **Average Directional Index (ADX)**. Additionally, the script provides visualizations and logic to identify trends and key levels. Below is a detailed explanation of how to use this script:

---

### 1. **Function `dirmov(jarak)`**:
This function calculates the **+DI (Plus Directional Indicator)** and **-DI (Minus Directional Indicator)**.

- **Input**:
- `jarak`: The period used for calculation (in this script, `14`).

- **Process**:
- `naik = ta.change(high)`: Calculates the change in the high price (upward movement).
- `turun = -ta.change(low)`: Calculates the change in the low price (downward movement).
- `truerange = ta.rma(ta.tr, jarak)`: Calculates the **True Range (TR)** smoothed using RMA (Rolling Moving Average).
- `plus`: Calculates +DI by comparing upward (`naik`) and downward (`turun`) movements.
- `minus`: Calculates -DI by comparing downward (`turun`) and upward (`naik`) movements.

- **Output**:
- Returns the values of `plus` (+DI) and `minus` (-DI).

---

### 2. **Function `adx(dilen, adxlen)`**:
This function calculates the **ADX (Average Directional Index)**, **+DI**, and **-DI**.

- **Input**:
- `dilen`: The period for calculating +DI and -DI.
- `adxlen`: The period for calculating ADX.

- **Process**:
- Calls the `dirmov(dilen)` function to get the values of `plus` (+DI) and `minus` (-DI).
- Calculates ADX by comparing the difference between +DI and -DI, then smoothing it with RMA.

- **Output**:
- Returns the values of `adx`, `plus` (+DI), and `minus` (-DI).

---

### 3. **Variables and Plots**:
- `[sig, up, down] = adx(14, 14)`:
- `sig`: The ADX value.
- `up`: The +DI value.
- `down`: The -DI value.

- `RatioNT = up - down`:
- Calculates the difference between +DI and -DI. This value represents the relative strength between the upward and downward trends.

- `Garis_ratioNT = ta.sma(RatioNT, 14)`:
- Calculates the Simple Moving Average (SMA) of `RatioNT` with a period of 14. This is used as a key level to identify trend changes.

- **Plots**:
- `L1 = plot(RatioNT, 'Trend', ...)`:
- Plots the `RatioNT` value as a trend line. The line color changes based on whether `RatioNT` is above or below `Garis_ratioNT`.
- Green (`#00d36880`) if `RatioNT > Garis_ratioNT` (strong uptrend).
- Red (`#fe585880`) if `RatioNT < Garis_ratioNT` (strong downtrend).
- `L3 = plot(Garis_ratioNT, 'KeyLevel', ...)`:
- Plots `Garis_ratioNT` as a key level (blue line, `#1848cc`).

- **Horizontal Lines (HLine)**:
- `hline(0.8, 'Top', ...)`: A horizontal line at the `0.8` level (pink color, `#fe585850`).
- `hline(0, 'Mid', ...)`: A horizontal line at the `0` level (black color, `#00000050`).
- `hline(-0.8, 'Bottom', ...)`: A horizontal line at the `-0.8` level (green color, `#00d36850`).

### 4. **How to Use This Script**:
This script can be used to:
1. **Identify Trends**:
- If `RatioNT` is above `Garis_ratioNT` and colored green, it indicates a strong uptrend.
- If `RatioNT` is below `Garis_ratioNT` and colored red, it indicates a strong downtrend.

2. **Identify Key Levels**:
- `Garis_ratioNT` (blue line) is a key level that can be used as a reference to confirm trend changes.

3. **Use Horizontal Lines**:
- The horizontal lines at `0.8`, `0`, and `-0.8` can be used as overbought/oversold levels or trend confirmation levels.

4. **Trading Signals**:
- **Buy Signal**: When `RatioNT` crosses above `Garis_ratioNT` and turns green.
- **Sell Signal**: When `RatioNT` crosses below `Garis_ratioNT` and turns red.

---

### 5. **Visual Interpretation**:
- **Uptrend**:
- `RatioNT` is green and above `Garis_ratioNT`.
- `RatioNT` approaches or exceeds the `0.8` level (pink line).

- **Downtrend**:
- `RatioNT` is red and below `Garis_ratioNT`.
- `RatioNT` approaches or exceeds the `-0.8` level (green line).

- **Sideways/Consolidation**:
- `RatioNT` fluctuates around the `0` level (black line).

---

### 6. **Example Trading Signals**:
- **Buy Signal Example**:
- `RatioNT` crosses above `Garis_ratioNT` and turns green.
- `RatioNT` approaches the `0.8` level (confirms strong uptrend).

- **Sell Signal Example**:
- `RatioNT` crosses below `Garis_ratioNT` and turns red.
- `RatioNT` approaches the `-0.8` level (confirms strong downtrend).

---

### 7. **Conclusion**:
This script is a useful tool for:
- Identifying the strength and direction of trends.
- Providing trading signals based on the movement of `RatioNT` and `Garis_ratioNT`.
- Offering key levels for trend confirmation.
