Money Management EA Based on Percetage of Equity

Hi all, I need to have a Money Management EA based on percentage instead of the number of pips that we normally have. The conditions are as below

When we open the position (Manual), the EA will set all the following for each individual order on multiple pairs.

1) Preliminary Stop Loss 2% of the account equity

2) Preliminary Take Profit 2% of the account equity

3) when an individual pair reaches over 1% profit, stop lost will move to 1 pip over the opening price and take profit will move to to 3%

4) when an individual pair reaches over 2% profit, stop loss will move to 1% profit level and take profit will move to 4%

5) when an individual pair reaches over 3% profit, stop loss will move to 2% profit and the take profit is set to 10%

6) At the same time action 5 is initiated the Stop loss is also set to trail the current price by the current pip difference between the current stop loss and current price.

* If possible, on the screen shows recommended lot size based on the money management 2% risk too.
