EA to manage Trailing SL/TP, Partial/Full Closure based on Proportionated ATR Reading

Hello Programming Gurus,

Majority of EAs manage Trailing Stop Loss, Trailing Take Profit with pre-set incremental stepping, either in pips or points.

I wish to have an EA that work out incremental Steps based on a ratio applied to the ATR reading taking off a chart on a chosen time frame. 

The zipped PDF file attached herewith explains the requirement in details.

Fee is negotiable, depending how much the EA can achieve.

In brief, the concept and functions are as follows: 

Concept

1. The EA will take the ATR reading (literally, with same decimal places as price)

     of a forex pair at any Time Frame, ie: H1, H4, D1.... etc

2. User sets the multiplicational factors (eg: 1.5, 1, 0.5, 0.75 ... any positive numbers)

     As ratio to be applied onto ATR for respective TPs and SLs.

     eg: A Long trade on AUDUSD, Opening Price [OP] = 0.66000, ATR=0.00500,

           SLi, initial SL to be set at 1.5*ATR away from OP,  

=> 0.66000-1.5*0.00500 = 0.66000-0.00750 = 0.65250

           TP1, [initial] TP to be set at 0.5*ATR from OP,

=> 0.66000+0.5*0.00500 = 0.66000+0.00250 = 0.66250

 3. Stepped increments for SL and TP are also computed in n*ATR.

Functions:

-  Trailing Stop Loss/Take Profit/Partial or Full closure of a trade, which are supposed to be placed-order in lots of 5.

-  Trailing incremental steps based on pre-set (adjustable) ratios multiplication factors applied to ATR reading pertinent to a chart.

-  Options to apply to one chart or to all

-  User’s error handling

-  Send alert signal and push notification to mobile metatrader app.

-  Partially interactive. Accept user’s intermediate inputs (change parameter values) without having to reset entire procedure.

-   Multiple retry – in case the change hadn’t get to the broker
