Need a freelancer to assist on customization for my EA, it needs to adjust the equity trailing stop to base on open equity and not closed balance.

Hi, so the the ea has a an equity trailing stop feature with two inputs, they are below. 

equity trailing stop start (number field) 

equity trailing stop (number field) 

Currently the equity trailing stop looks at the open trade profit wheres as we need it too look at the current equity see below example

Starting balance 

10k 

Now it makes a profit to 500 so balance now is 

10,500

and equity is 10,300 with open trades down -200 

we want it to calculate on the basis of the 10,300 or account equity to starting balance of 10k so for instance 

if we set to start equity trailing stop at 3% and equity trailing stop at 1% this would trigger at 10,300 and equity trailing stop would be at 10,100 and once the open equity trailing stop is hit it would start on the new balance as the basis so say it hit at 10,100 now the starting balance is 10,100
