Modifications to existing MT4 EA

I have an ea that works fine. The EA is designed to close all the running trades when the Equity is equal to N$(amount of money) and stop trading on that day and it should start trade again on next day.
The problem is that the ea cannot start trading on the next days after the Equity is meet the condition. 
Is there any one can write code to update the amount in this condition after the equity is reach the specified Money. 
Ex: double is amount automatically after the main condition meet.
