EA which stops other EA on drawdown

I need an EA which watches positions of an other EA, calculates drawdown and stops that other EA for some predefined time if drawdown exceeds limit.
- There may be multiple trading EA's and manual orders. The Supervisor EA whatches positions of one predefined trading EA only (specified by magic number)
- it calculates equity (not for the whole account, but for the supervised EA). The highest is used as reference for drawdown calculation
- If drawdown exceeds limit (set by Input), it cloose related open positions and stops the trading EA by switching template of chart where the trading EA is applied to (in that template algo-trading is disabled)
- After predefined time it may enable other EA by switching back the template to one where algo-trading is enabled
- There may be multiple Supervisor EA's installed at a time, each controlling one trading EA
- There shall be simple UI which shows current reference equity (from which drawdown is calculated) and current drawdown, as well as Enable/Disable-Status of controlled EA
- There may be an STOP/Enable switch on the UI which does the enable/disable Logic manually (optional,not required)
- I need source code
