EA for simple Hedge trade instead of trailingstop

From scratch > clean code please!

Hedge a manually opened order;

On a manual trade, your EA opens a (pending order) HEDGE trade of the same lotsize and follow price just like a trailingstop.

Inputs:
order comment (hedgethis)  > if the order is opened with this comment the hedge should be created instantly
Hedge distance (in pips)  > The distance of the hedge trade if the initial order is opened in pips.
Magic number? > I want to be able to open many manual trades on 1 chart and they all should be hedged (trailed) 

Example:

1LOT manual BUY trade on price 1.78900 opened manually with comment "hedgethis"
Hedge distance is 10 pips  so the hedge (Sell stop) order should open @price 1.78890 

Price moves to 1.78905 
Hedge moves to 1.78895

Price moves back to 1.78900
Hedge stays at 1.78895

Price then moves to 1.78910
Hedge moves to 1.78900

In short: if price moves in favor of the initial trade it should follow the initial trade, if price moves against the initial trade the hedge should lock the best level it has reached
