Create an Indicator to Display the Mean of Ultimate Oscillator for Multiple Timeframes

Developer Task: Indicator to Display Mean of Ultimate Oscillator Across Multiple Timeframes

Objective:
Create an MT5 indicator that calculates and displays the mean of the Ultimate Oscillator for the timeframes M3 , M4 , and M5 . The indicator must function consistently across any chart timeframe (e.g., M1, H1, etc.).

Requirements:

1. Input Parameters:

   • input int MaxBars = 5000; → Limit bars loaded for calculation.
   • input int UpdateInterval = 180; → Update interval in seconds. If set to 0 , reload every tick.

2. Timeframes and Handles:
   Use the following handles to load the Ultimate Oscillator:

   • int handle_M3 = iCustom(_Symbol, PERIOD_M3, "Examples\\Ultimate_Oscillator");
   • int handle_M4 = iCustom(_Symbol, PERIOD_M4, "Examples\\Ultimate_Oscillator");
   • int handle_M5 = iCustom(_Symbol, PERIOD_M5, "Examples\\Ultimate_Oscillator");

3. Calculation:
   Calculate the mean value of the Ultimate Oscillator from the three timeframes.

4. Consistent Value Display:
   The indicator must display the same value on any chart timeframe.
