Need to add Money management functions + Limit orders to my EA

Hi all,

I have an Ea able to take stop orders (buy stop and sell stop) on a certain time frame. It's also able to calculate the lot size of the trade regarding the risk I accept and where I want it to put the stop. ( Autolot function ).

I want to add some functions : Money management functions + Limit orders.

Money management functions : 

Partial close the first trade + BE.

Add 2nd positions at a certain ratio of 1st stop (or pips in profit from the 1st trade) 

Partial close the second trade, and being able to calculate the average price of both trades (1+2)

Add 3rd positions at a certain ratio of 1st stop (or pips in profit from the 1st trade) 

Partial close the third trade, and being able to calculate the average price of both trades (1+2+3) 

and so on

Limit orders : 

Able to place and manage buy and sell limit orders the same way.

I'll provide a precise guide with graphs and explanation. 

Thanks to apply only if you're sure you can do it
