First of all, I'd like to say thanks to this forum and the great coders mrtools and mladen who make our trading much easier. 4Sessions indi draws this rectangle with first template load, but I don't need it. Other rectangles are drawn correctly. When I load this template for the second time it fortunately disappears. Could this one be fixed and removed?
No other indicators are needed.
Thank you in advance.
