Add hedging function to the existing EA

We need to add hedging option to our EA. For example if we have 0.01 lot buy and the price moves 5 dollars opposite it opens hedge position with 0.02 and when the profit of hedge position equals or exceeds to the loss of the main position (0.01 lot initially opened) it closses both of them. In another case after opening the hedge position if price returns to the first opened order it again closes both of them

Here we need some functions

1.  On/of function for hedging

2. Size of opened hedge position (0.01,0.02 and etc)

3. Distance that the hedge position will be opened ( for example after 5, 10, 50 points)

4.  Take profit distance for hedge position
