I Need A Box Re-drawing

I´d like to get some help from people here. I´m looking for a program that draw a box (rectagle) with the next observations:

The WIDTH must to contain inside the last 24 candles,

The HEIGHT must to contain inside the higher high and the lower low of the last 24 candles.

The BOX must to be redrawn when a the next new candle had finished, and so on.

Every new BOX must to regard the new higher high and the lower low, there were if them.

Any ideas????

Have a play with this Range Breakout Alert from Zen Leow.
You should be able to set it to your 24 bars. If the other parts are in the way, comment them out with a // at the start of the lines.
Sorry I didn't record where I got it from - I normally do.

If you change time frames, it does a recalc based on the new chart & may not be what you expect. It does reset to what it originally showed if you change the timeframe back.
