I want to create an EA to manage SL TP levels while I open trades manually

Features of the EA 

1-auto stop loss calculation based on equity risk %

for example 

Lot size = 0.1

equity is 1000 usd 

risk % = 1

then stop loss pips value = 10 $

2- auto take profit based on equity %

for example 

equity = 1000 usd

take profit % = 1%

take profit pips value = 10 usd 

3- breakeven based on TP % 

for example take profit = 10 $

breakeven = 3 % of take profit value

breakeven is activated when 3 of 10 $ value achieved

works on market and pending orders 

magic number to control all existing trades ( market and pending )
