Indicator for average price of candles

Hi

I would like to get an indicator which draws a point in a graph showing the current average price of the current candle. Once the candle is done, the point is fixed onthe graph and the average price for next candle is being displayed. A line shall join average prices of candles.

Average price of a candle is the average price of all prices received for teh candle ticks.
There shall be options to add weights the the average price :
- no weight
- by time
- by volume
- by time and volume

There shall be an optoin to chosse the color of the average points and lines

Here is a simple exemple :

candle 1 minute from 12:00 to 12:01, only 3 ticks (to make it easy) :

tick 0 at 11:59 30 seconds price 0.9999 volume 5

tick 1 at 12:00 10 seconds  price 1  volume 10
tick 2 at 12:00 20 seconds  price 1.0001 volume 20
tick 3 at 12:00 45 seconds price 1.0002 volume 30

At the end of the candle, at 12:01:

average with no weight is (0.9999+1+1.0001+1.0002)/4

average by time is (0.9999*10 (duration of the price in seconds during the candle time frame) + 1*10 + 1.0001*25+ 1.0002*15)/60 (seconds)

average by volume is (0.9999*5 + 1*10 + 1.0001 * 20 + 1.0002 * 30)/(5+10+20+30)

average by time and volume is (0.9999*10 (duration)*5 (volume) + 1*10*10 + 1.0001*25*20+ 1.0002*15*30)/(50 (first weight)+100+500+450)

Note that those calculations shall be used during the candle time frame to update the candle average price for each tick.
