Here are the key points and features of the Pine Script provided:
### 1. **Indicator Settings**: - The indicator is named **"POINT and Shoot"** and is set for non-overlay (`overlay=false`) on the chart. - `max_bars_back=4000` is defined, indicating the maximum number of bars that the script can reference.
### 2. **Input Parameters**: - `Src` (Source): The price source, default is `close`. - `rsilen` (RSI Length): The length for calculating RSI, default is 20. - `linestylei`: Style for the trend lines (`Solid` or `Dashed`). - `linewidth`: Width of the plotted lines, between 1 and 4. - `showbroken`: Option to show broken trend lines. - `extendlines`: Option to extend trend lines. - `showpivot`: Show pivot points (highs and lows). - `showema`: Show a weighted moving average (WMA) line. - `len`: Length for calculating WMA, default is 9.
### 3. **RSI Calculation**: - Calculates a custom RSI value using relative moving averages (`ta.rma`), and optionally uses On-Balance Volume (`ta.obv`) if `indi` is set differently. - Plots RSI values as a green or red line depending on its position relative to the WMA.
### 4. **Pivot Points**: - Utilizes the `ta.pivothigh` and `ta.pivotlow` functions to detect pivot highs and lows over the defined period. - Stores up to 10 recent pivot points for highs and lows.
### 5. **Trend Line Drawing**: - Lines are drawn based on pivot highs and lows. - Calculates potential trend lines using linear interpolation and validates them by checking if subsequent bars break or respect the trend. - If the trend is broken, and `showbroken` is enabled, it draws dotted lines to represent these broken trends.
### 6. **Line Management**: - Initializes multiple lines (`l1` to `l20` and `t1` to `t20`) and uses these lines for drawing uptrend and downtrend lines. - The maximum number of lines is set to 20 for uptrends and 20 for downtrends, due to a limit on the total number of lines that can be displayed on the chart.
### 7. **Line Style and Color**: - Defines different colors for uptrend lines (`ulcolor = color.red`) and downtrend lines (`dlcolor = color.blue`). - Line styles are determined by user input (`linestyle`) and use either solid or dashed patterns. - Broken lines use a dotted style to indicate invalidated trends.
### 8. **Pivot Point Plotting**: - Plots labels "H" and "L" for pivot highs and lows, respectively, to visually indicate turning points on the chart.
### 9. **Utility Functions**: - Uses helper functions to get the values and positions of the last 10 pivot points, such as `getloval`, `getlopos`, `gethival`, and `gethipos`. - The script uses custom logic for line placement based on whether the pivots are lower lows or higher highs, with lines adjusted dynamically based on price movement.
### 10. **Plotting and Visuals**: - The main RSI line is plotted using a color gradient based on its position relative to the WMA. - Horizontal lines (`hline1` and `hline2`) are used for visual reference at RSI levels of 60 and 40. - Filled regions between these horizontal lines provide visual cues for potential overbought or oversold zones.
These are the main highlights of the script, which focuses on trend detection, visualization of pivot points, and dynamic line plotting based on price action.
