Hidden Trailing Stop Profit and BE

Hi all I want a trade management EA that can trailing my multiple position but not shown as SL, just close all when the condition met.

Here is the scenario

I have 4 buy position of EurUsd with averaging method, when accumulative profit goes to BE, the EA start to manage the trade and will close whenever it backs to zero. When it continues to my favor, for example after profit of 10 pips from BE point, it will start the trailing feature. And will close when it back to 7 pip profit (70% value). If the profit not reach 10 pips, so it will close at BE point or zero value. If the price continue to maximum 30 pips profit, it will close at 21 pips (70% value). 

 To control the desired position we can use magic number or comment to filter.

Remember that closing method is not using SL line, just do like we do it manually using hand. And please keep in mind, I want using pips as profit not dollar value, why? because if i use dollar i cant use it for all possible position that may have 0.01 lot until 10 lot. if I use for example 10usd profit it will too large for 0.01 lot but too small for 10 lot, so i want using pips value. 

Here is the input i want to have

Magic number = 

Comment = 

Start_trailing_in_pip = 

Trailing_step_in_pip =

Trailing_stop_in_percentage = 50

If you have any question please let me know
