Mt5 Expert Advisor - multi pair, session based, Risk management, auto lot size sl/tp

I need a mt5 Expert advisor ea to manage intraday trades with strict risk management.

The EA must

-Handle between 5 to 8 clean trades a day max altogether throughout all 3 sessions. no big  news  trading times and no overnight trades

-Use 1%  on forex pairs and   upto 2% on XAUUSD risk per trade

- Automatically calculate lot size based on stop loss

-use fixed RR ratio [1:2]

For forex pairs, the stop loss should be adjustable within a 20/40 pip range depending on market conditions and pair volatility

Lower volatility pairs should use smaller stop losses {around 20 pips} while higher volatility pairs should use larger stop losses {around 40 pips}

For  XAUUSD the stop loss should be adjustable within a 50-80 pip range depending on market conditions

The EA must automatically calculate lot size based on the selected risk percentage  and stop loss.

Take profit should follow a fixed 1;2 risk  to reward ratio.

XAUUSD must be handled separately from forex pairs with its own stop loss settings

Th EA must be fully testable and functional on a mt5 demo account and must work correctly and assist

 with intial set up and testing if required before final delivery 

Include manual lot size override
