Custom Indicator Job: Historical & MTF "Technical Ratings" just like the one from trading wiew

Hello MQL5 Developers,

I would like to hire a developer to create a high-quality custom indicator for MT5. The goal is to perfectly replicate the logic of the TradingView "Technical Ratings" summary, but with the crucial feature of displaying its historical values as lines on the chart.

I will attach an image to this post that shows the exact logic and structure I need.

Core Logic (as shown in the attached image):

The calculation is a straightforward average of signals from two main groups: Oscillators and Moving Averages.

1. Each of the ~26 underlying indicators provides a rating: +1 for "Buy", 0 for "Neutral", or -1 for "Sell".
2. The final "Summary" score is the simple mathematical average of all these individual ratings.
3. Example from the image: The summary shows 10 Buy, 8 Neutral, and 8 Sell signals. The calculation is:
   (10 * +1) + (8 * 0) + (8 * -1) = +2 .
   This total is then divided by the number of indicators (26): +2 / 26 ≈ +0.077 .
4. This final score of +0.077 falls within the Neutral range (-0.1 to +0.1), which is exactly what the summary gauge shows. This is the precise logic that needs to be implemented.

Key Features Required:

• Historical & Non-Repainting: The indicator must calculate and display the rating for every past candle, not just the current one. on the chart with different color lines. It must be 100% non-repainting.
• Multi-Timeframe (MTF) Lines: It must show multiple, separate lines in an indicator sub-window. The user must be able to define the timeframes in the settings (e.g., M1, M5, M15, H1, H4, D1).
• Color-Coded Lines: Each line must change color based on the final score to provide an instant visual analysis. The ranges are:
  • Strong Buy: +0.5 to +1.0 (e.g., Green color)
  • Buy: +0.1 to +0.5
  • Neutral: -0.1 to +0.1 (e.g., Blue or Grey color)
  • Sell: -0.5 to -0.1
  • Strong Sell: -1.0 to -0.5 (e.g., Red color)
• EA Compatibility: The indicator's values for each timeframe line must be easily accessible from an EA via iCustom() buffers, as it will be used to drive a grid trading bot.

Please review the requirements and the attached image. I am looking for a developer to build this as a robust and reliable tool for automated trading.

Let me know your price quote and estimated delivery time.

Thank you.
