Breakout Indicator Fix

Hi guys, 

How it works:

When we have a 20 candles in the range of 20pips (just an example) it starts
drawing a grey box. (pic.1) This box is extendend with every new
candle until the price will break it (pic.2). When price breaks
the grey box it draws colored boxes with tp1/tp2/tp3.
When breaking to the upside it gives blue, and to the downside
it gives red boxes. Colored boxes are being drawn for the next 30 candles (pic.3.),
then start over and look for another grey box.

Now, everything works very good when MT4 is open. The problem
starts when I close the MT4 (when box is formed), and then open
it again. I get this (pic4). The box is extended to the actual candle.
After refreshing (changing TFs) it's back to normal (pic5). 

Maybe someone has an idea how to fix this. 

Thank you
Best regards
