EA to manage trades

I need to manage trades. I place the trade manually but the EA manages trade sequence to the end.

Description of what is needed:

1.   EA must be able to take second trade and manage up to 20 trades. I need to have the option on choosing before starting how many trades the ea will take before closing all trades. From 2 - 20.

Every trade that   the Ea takes is in the opposite direction of previous trade.

I need the option of choosing a multiplier for the next trade

- Example: I have chosen a 10 pip gap between sell and buy, and the multiplier 1.5, if we have 3 open   1 sell= 0.1lot   2buy= 0.15lot    3sell=0.13lots, now this sequence goes against us and the EA opens the 4 trade buy which would be sum of all previous sell trades (0.1+0.13)=0.23 * the multiplier 1.5 =                                0.34 - sum of all previous buy trades 0.15 . End trade would be 0.19lot

2. I need to be able to choose the t.p for each leg in the sequence. 

Trade 1    5pips or 15pips any number I want.

Trade 2  BE + 5pips

        Trade 3    BE + 5pips 

Trade 4  BE + 5pips

Trade 5  BE + 1pips

        Trade 6   BE + 1pips

Trade 7  BE. 

and following til trade nr20

EA must have a panel on chart.

This control panel must show what equity was when first trade is taken. Must show profit or loss as a total sum of all trades ongoing including commission. Also show profit or loss of all buy trades and sell trades.

The control panel must have these buttons:       -Buy button (market order)

     -Sell button (market order) 

             -Close all trades 

     - Hedge (if pressed the EA takes a position so lot sizes are equal in both directions), I would use this before news. Then when the hedge is taken of the Ea returns to trade like summing the closed hedge position to its sequence of trades (Im not sure how this can be solved)
