Dynamic Stop Loss

I'm using paid signals either:

1. market orders or

2. pending orders.

Both of them have given trade information:

1. currency pair,

2. entry price (when it is market executed it is just for reference),

3. stop loss,

4. take profit 1,

5. take profit 2,

6. take profit 3.

The trade strategy is:

1. to set stop loss and take profit 3,

2. if take profit 1 is hit then close 60% of the initial position and move stop loss to entry price,

3. if take profit 2 is hit then close 20% of the initial position and move stop loss to take profit 1 level.

My wish:

1. Generally I would like an EA to easily handle this process.

2. Display of the currently controlled positions and their trade information on the chart window.

Remarks:

1. The money management may be simple by just setting the lot size for TP1, TP2, TP3 in the EA.
   

2. Since that MT4 terminal for PC can't close the position partially this mean that the position will be executed as 3 deals but controlled as 1 position.

3. I would like to have bouth source code and final binary *.ex4

4. Later the developer should be able to modify the EA for MT5 at reasonnable low cost compared to the initial payment.

5. EA updates to new MT versions if necessary to be free of charge.

6. EA small modifications to be free of charge, medium modification to be at low cost.
