_2523MTF_HULL_TREND

This script is designed to display a modified version of a Hull Moving Average (HMA) on a trading chart, but with a twist: it allows you to view the HMA calculated on a different timeframe than the one currently displayed on your chart.

Here's the breakdown:

Timeframe Selection: The script starts by letting you choose which timeframe's HMA you want to see. You can select from options like 1-minute, 5-minute, 1-hour, daily, etc. If you don't choose a specific timeframe, it defaults to the current chart's timeframe.
HMA Calculation Setup: The script then takes your selected timeframe and sets up the parameters needed to calculate the Hull Moving Average. These parameters include:
- The period of the HMA, which essentially determines how many past data points are used to calculate the average.
- The price to be used (open, close, high, low, etc.)
- A displacement which basically defines how the hull moving average is shifted relative to the current bar.
Data Retrieval and Calculation: The core of the script involves retrieving historical data (prices) from the selected timeframe. It then calculates the Hull Moving Average based on these prices and using the user-defined parameters, just as any other Hull Moving Average indicator. It retrieves two sets of HMA values from another custom indicator named "Hull Trend".
Displaying the Results: Finally, the script plots these two sets of HMA values as lines on your current chart. These lines visually represent the Hull Moving Average calculated on the chosen timeframe, superimposed on your current chart's price action. The two lines are displayed in different colors (hot pink and aqua) to differentiate them.
