Grid EA

my basic idea is :

let assume that this is a buy grid only so it will be easy to explain, the sell grid is the same as buy just opposite rules.

1. the grid will trade buy orders only with the trend. (we will use a indicator to defined the trend a cross of moving avg or other method)

2. when the trend his ending hedge all position and wait a new bullish trend.

3. when we are in a bullish trend and price go down we add more buy orders in lower prices until the trend is change , i think when we adding new position we should add more contract for example , first order is 0.1 second order is 0.2 third order is 0.3 etc...

4. we need to be able to define the size of step to add new orders.

5. I'm not sure about the tack profit , in what mechanism we should close all the trades , maybe on % gain.
