Developing an MT5 Expert Advisor Based on a Similar Model

Looking for an MQL5 developer for an expert advisor with logic similar to this one:
https://www.mql5.com/ru/market/product/179810

Key approaches to implement:

1. A mean-reversion strategy using BB + RSI for XAUUSD. Entries target extremes, not trends.
   A basket of orders with a common SL/TP.
   A maximum of 3 averaging steps (no martingale). 
2. Impulse Guard — H1 + H4 analysis, impulse score (ADX + price/MA distance in ATR + candle sequence + ATR spike). If the score reaches a certain threshold, the entry is blocked. 
3. Dynamic TP Decay — if the basket remains open for a long time, the TP is gradually reduced. 
4. Grid Evacuation — tight TP on the last legs; they close together with the first leg. 
5. Prop Firm mode — daily limit, trailing DD, limit on additional funding. 
6. Automatic news filter via the MT5 Calendar. Blocks trading before/after major news events. It should work the same way as in this expert advisor, even in the tester. You need to create a list of news events in the code that it will use in the tester. 
7. It also includes other important filters that need to be set up: Global Trend Filter / MTF Guard (Major Trend Filter), Tick Volume Filter, ATR Spike Filter (Protection Against Sharp Spikes),  Equity Guard, Loss Streak Cooldown.

Important:

• Write your own code; do not copy. 
• No AI allowed.
• The result must be comparable in quality.
• Budget to be discussed.

Perhaps not all of its features are necessary, but ultimately, it should perform in the backtester roughly the same as the original:
