General Logic 
1- Start by Placing First B/S 
2- Next 300 point Place Second B/S 
3- Next 300 point place Third B/S
4- Watch the price movement 
5- If the Total movement from first B/S exceed the Third B/S by 100 point then (total movement equal to 700 points)
6- Take first Profit i.e. 700 point then place hedge position B2 OR S2 According to the movement was it up or down. 
7- When ea take first Profit (700) then place all pending order above first B/S and Down Hedge order 
8- B/S will take profit each 700 points and Hedge Orders each 300 and so on. 
9- If e.g price move down to 700 the ea will take 700 profit, and place hedge position S, in case the price retrace back to the first B/S in this case S was taken as profit and B remain active, keep B alone and don't put S one more time. B/S will be place only after new 300 point.
