#MTF Forex freedom Bar

Based on the provided MQL4 code, this appears to be a custom indicator designed to analyze multiple timeframes and display support and resistance levels using CCI and SuperTrend indicators. Here's a breakdown of its key features and functionalities:

Timeframe Selection:
- The indicator supports 9 different timeframes: M1, M5, M15, M30, H1, H4, D1, W1, MN1.
- It automatically selects the appropriate timeframes based on the current chart timeframe.
CCI and SuperTrend Calculation:
- CCI (Commodity Channel Index) is calculated for each selected timeframe.
- SuperTrend indicators are used to determine support and resistance levels for each timeframe.
Displaying Support and Resistance Levels:
- The indicator displays horizontal lines representing support and resistance levels on the chart.
- Each line corresponds to a specific time frame, with different colors or offsets to distinguish them.
Customizable Parameters:
- Users can customize the number of CCI periods (currently set to 50).
- The gap between support and resistance lines for lower timeframes is adjustable through the Gap parameter.
Dynamic Timeframe Selection:
- If AutoDisplay is enabled, the indicator will dynamically adjust its timeframes based on the current chart timeframe.
- This means that if you're looking at a 1-hour chart, it might automatically switch to using 15-minute, 30-minute, and 4-hour charts.
Support and Resistance Logic:
- The logic for determining support and resistance levels is based on the SuperTrend indicator's output.
- If the CCI value is below zero, it sets a "support" level; otherwise, it sets a "resistance" level.
Indicator Customization:
- Users can set parameters such as Period_1 to Period_4 to customize which timeframes are used.
- The indicator also allows for manual setting of the SuperTrend settings through the iCustom() function calls.
New Bar Detection:
- The NewBar() function checks if a new candle has formed, triggering updates to the indicator's calculations.

Key Functions and Variables

start(): Main execution function.
SetValues(int p1, int p2, int p3, int p4): Sets the timeframes for different levels.
SetAutoDisplay(): Configures the dynamic timeframe selection based on the current chart.
NewBar(): Detects when a new bar is formed to trigger updates.

Potential Improvements and Considerations

Error Handling: Add error handling, especially around iCustom() calls to ensure they don't fail due to missing or incorrectly named indicators.
Performance Optimization: Ensure that the CCI and SuperTrend calculations are optimized for performance, especially on lower timeframes where data can get large quickly.
User Interface: Consider adding a GUI control panel within MetaEditor to allow users to easily change parameters without needing to edit the script directly.

This indicator could be useful for traders who want to see support and resistance levels across multiple timeframes dynamically adjusted based on their current view, but it would benefit from some refinement in terms of usability and performance.
