I need an ea trade manager

What I'm after is an expert Advisor that will place a buy/sell box on the chart for a manual entry using my own analysis.

The box is to include risk percentage option to two decimal places and a stop number in pips that can both be set by the user.

 I have included a picture of the ea I'm using as I want something similar?

 My big problem that I need the help with, is the management, what I do is if an open position goes against me, I do a stop and reverse.

I'm using a martingale style grid technique where trades will continue to be executed (buy,sell,buy,sell...) until the market eventually moves

away from the area enough to generate a profit.

My risk to reward ratio is not 1/1 so lot size increments are not doubled, I have a X(times) by number to match the r/r.

if the trade does not reach profit after x amount of entries, the lot size stops increasing and I switch to increasing the profit targets,

can this be done with an ea? 

Each trade is closed as the next one opens, so there is only ever one open position.

I'm confident I have a management system the always ends with a profit without eating my account away or causing a margin call ect..
