Postioning Averge EA?

Postioning Averge EA?
Been looking at this and manually using it, Found it very interesting and pretty safe.

Steps
1. Place your first B/S order

2. Wait till either side is in positive pips to your liking

3. Close that positive side and enter another B/S order

4. Find the Postion Average for the 3 trades open and enter them in there correct SL or TP location

5. If one side goes down to cancel out or break even to 0 then repeat. If not then keep doing the same steps as #3

Hope someone code code this simple but complex order modifcations

Thanks

Could you please put up an example?

example

eurusd

buy 1.2500
sell 1.2498

price goes up to 1.2550
buy order is now up +50. I will close buy to take profit.
Enter another BUY/SELL order at 1.2550
modify the SL and TP of these 3 orders(take (1.2498+1.2550)/2=1.2524 )
Place this new value into the SL of the BUY order and TP of the SELL orders.
This will break even all 3 orders if it goes down.
If it should go up again then repeat again Enter another BUY/SELL

Hope its clear
