Two expert advisors A and B

Below you find my request for two expert advisors A and B;
What should they be doing:
A: Reverse position based on trailing stops:
Once there is a position (placed manually) it should have a trailing stop on an initial distance of ATR for x number of periods (trail is moving with every tick) with a minimum number of pips which can be adjusted manually; the position is reversed once the trailing stop is being hit.
The next position will be the same taken into consideration that the trailing stop for the next position will be a new ATR x number of periods then (with the same minimum).
So, besides the automated process I want to be able to decide and manage (maybe some kind of input box ?) the following at the beginning of "the loop" :

- the x number of ATR periods
- the money being risked and the minimum number of pips of the trailing distance in case the trailing is based on ATR.
- there should be a possibility in the program to adjust (at the beginning) the trailing distance manually with a fixed amount of pips (so you'll have the choice which way you start the process)
The risk should be based on a fixed amount of the account size (given manually, but for all no percentage) and remains the same during the process (only the value/pip or lot size changes which will be done automatically by the program).
For example EUR/USD:
buy e.g. at 1,3020, trailing based on ATR (3 periods) say 9 pips. Money at risk is 50 euro or dollar (amount which should be given manually) So the initial value of a pip in this case would be 50/9= appr. 5,5 euro/pip. Then when the trailing stop is hit and the position is being reversed the ATR (3 periods) is 11. For the reversed position (short instead of long) the new value of the pip is 50/11= approx. 4,5 euro/pip and the initial size now of the trailing stop is 11; and so on.

In general: the stops determine the profits/losses.

One more thing: the program should have a "stealth" mode to be able to set stops at less pips than officially allowed by the broker.

B: Reverse position with break-even-stops:
Once there is a position (placed manually) it should have a break even stop which is trailing and when the stop is being hit the position should be reversed with the same break-even stop. In this case a take profit level should be given manually in advance of the opening of the first position. The initial distance of the break even stop should be given manually as well. The pip value in this case stays the same during the process and is determined before beginning. At every reversal of the position the number of pips for the "take profit" stays the same.
So, besides the automated process I want to be able to decide and manage the following at the beginning of "the loop" :

- the number of pips for the break-even-stop
- the choice for trailing or not
- the take profit amount
- the initial value per pip/ lot size
The program should have a "stealth" mode too, hto be able to set stops at less pips than officially allowed by the broker
Hope this text is clear enough for you to program the EA's and can you give me a proposal for the price involved! In case you have any questions, please feel free to contact me !
