ReWrite Indicator for MT5

**I have the source for both MQL4 and MQL5 already, I need this simple indicator understood and rewritten**

I was told this indicator was old and was coded for MT4 therefor lacked better techniques of programming now available for MQL5

Key Changes I am looking for:

1. Removed unnecessary recalculations: The code repeatedly calculates values that could be computed once and reused. This is optimized by reducing recalculations inside loops.
2. Array handling improvements: The ArraySetAsSeries method is used more efficiently and unnecessary clearing of arrays is avoided.
3. Use of IndicatorCounted() : This function helps avoid recalculating already counted bars.
4. Removed complex, nested loops that don't add significant value, and used simpler logic for plotting and alerts.
5. General code cleanup: Improved readability and structure of the code.

I need this to be studied and rewritten, there is a mystery bug that causes the line the indicator forms to disappear after a day or 2

It will need to work on FX, Indices, Commodities, crypto etc

Code must run with out errors, warnings or Array issues

I will require Source file to mark order complete
