Input Parameters: The script allows the user to input values for the ATR length (atrPeriod) and the factor used in the supertrend calculation (factor). These input parameters make the script customizable and adaptable to different trading strategies.
Technical Analysis Indicators: The code utilizes various technical analysis indicators to generate trading signals and plot charts. It includes the Average True Range (ATR) indicator for volatility measurement, the Exponential Moving Average (EMA) for trend analysis, and the Supertrend indicator for identifying potential trend reversals.
Plotting Functions: The script employs plotting functions to visualize the data on the chart. It uses the plot function to display the middle value of the candle (average of open and close) but sets the display to display.none, meaning it won't be visible on the chart. The barcolor function is used to set the color of the bars based on certain conditions.
Trend Catcher Indicator: The code introduces a custom indicator called the "Trend Catcher." It compares the crossover and crossunder of two exponential moving averages (EMA 10 and EMA 20) to determine the trend direction. It assigns a value of 1 for a bullish crossover, -1 for a bearish crossunder, and 0 otherwise. The color of the bars is set based on the Trend Catcher indicator value.
