Ichimoku Hosoda waves's target price indicator (based on the formulas belove)

Hi programmers. I'm an italian ichimoku-trader. I have a very simple request. I need someone create me an indicator able to trace horizontal lines wich are hosoda targets prices.

Three buttons are required. The "Draw" button, the "DEL" button and a button for changing the color of the lines and targets. (because sometimes the trader need to draw multiple waves on chart and Targets of differents waves can collide in the same point).

The mechanism is the following:

1. A point: The trader click on the candle in the high/low wich is the "A point" (tip: the indicator automatically identify the high/low of the candle when the trader click on it).

2. B point: click one second time in the high/low of another candle wich is the "B pont" of target's calculation.

3. C Point: Click one third time in the high/low of another candle wich is the "C Point".

4. The indicator automatically draw the "Target Point" in the chart: that virtually can be one of the 4 horizontal lines targets  based on the underlying calculation. (view image attached)

---> Target "V": B+(B-C)

---> Target "N": C+(B-A)

---> Target "E": B+(B-A)

---> Target "NT": C+(C-A)

The indicator draw ALL of the four targets.

4. When trader click on "DEL" button the targets are deteled

The indicator's purpose is drawing on chart the Hosoda waves's target price. (Ichimoku strategy).

I think is not a very difficult task! :) 

 PS: I edit a little bit the description (i forgot point 3), read it pls.
