Indicator - creating an objects

Hi,

I've made an indicator which presents areas which are used to create ichimoku line.

But I have a problem.

I'm not a programist, so the indicator has a problem with refreshing shapes which are based on current price.

My goal:

1. Create indicaton which will have extern double TS, KS, SSB.

2. For each of extern double will be created rectangle where width  shall be equal to number of bar indicated in those doubles TS, KS, SSB.

3. High of each of rectangles shall be drawn as max and min for TS, KS, SSB,

4. The rectangle shall be redrawn after changing current max or min price.
