Code an ea to switch autotrading off if certain variables are met

I would need an script/indicator that enables the "AutoTrading" option (i mean that one on: Tools-Options-Expert Advisors-Allow automated trading) at a specific time "variable" of the day , at the same time if the value "variable" of a cross  has reached a specific value " variable".

the activation process of the "AutoTrading" is the main purpose so I would like the indicator to have the option that makes me choose whether the activation is determined only by the time or by both time and price at the same time.
