Description & Settings
The indicator plots two lines on the chart: one for the high price and one for the low price, calculated based on user-defined inputs. Its key features include:
Customizable Timeframe
: Users can select a timeframe (e.g., daily, hourly) using the TimeFrame input, with a default of PERIOD_D1 (daily). The indicator ensures the selected timeframe is not smaller than the chart's current timeframe to maintain data accuracy.
Price Calculation Options
: The Price input allows users to choose between three modes:
Low/High (DHL_LOWHIGH)
: Plots the highest and lowest prices of the specified timeframe.
Open/Close (DHL_OPENCLOSE)
: Plots the maximum of open/close prices and the minimum of open/close prices.
Close/Close (DHL_CLOSECLOSE)
: Plots the highest and lowest closing prices.
Previous Period Option
: The Previous input (default: true) allows users to display the high/low of the previous period, aiding in historical analysis.
Visual Customization
: The indicator uses solid silver lines for both high and low plots, with a width of 1, ensuring clear visibility without cluttering the chart.
How It Works
The indicator operates by initializing two buffers (HighBuffer and LowBuffer) to store and display the high and low price levels. During initialization (OnInit), it sets these buffers and validates the timeframe. The core logic resides in the OnCalculate function, which processes price data for each bar:
Data Preparation
: Arrays for time, open, close, high, and low prices are set as series for reverse indexing.
Timeframe Alignment
: The indicator calculates bar shifts using iBarShift to align data with the selected timeframe.
Price Calculation
:
For DHL_LOWHIGH, it directly fetches the high and low prices using iHigh and iLow.
For DHL_OPENCLOSE and DHL_CLOSECLOSE, it identifies the highest/lowest open or close prices within the timeframe using iHighest and iLowest.
Previous Period Handling
: If Previous is enabled, calculations shift to the prior period, providing historical context.
Optimization
: The indicator limits calculations to new or updated bars (limit) to ensure efficiency and avoid redundant processing.
