Script to test manually my indicators historical in strategy tester

Hi everyone,

I want to manually test and analyze my indicators with the "Strategy tester".
It may be similar to the LFH Trading simulator. (Link: http://www.forexfactory.com/showthread.php?t=70742)

I have already tried several simulators. Unfortunately, I found no one who does what I want.

I need an EA (like LFH) and two scripts (long and short) that trigger a market order and simultaneously show two lines representing the stop and the target.
By positioning the stop, the Lot Size is calculated. The target and the stop must always be displaceable or customizable. Simply by moving the lines up or down. On the left of the target line, the risk/reward ratio should be displaced (e.g. 3.6). If I move the target, the display of the risk/reward ratio have to be adjusted or updated.

What variables should be set in the EA.
1. Risk in Percent
2. Target sell 50% or 100% of the position
3. Color Target
4. Color Stop

The lot size is calculated by the difference between the open of the next bar with the distance to the stop and the available capital.

Calculation Lot size:
Buy Example:
1.2500 = Open next bar, 1.2450 stop line, $ 10.000 account, risk 2%
