opening range lines

[idris]

Hi I  wanted to make a suggestion for bookmap platform development, we trade the opening ranges on NQ ES, i was wondering if bookmap developers could add a indicator where we can have horizontal lines  drawn automatically at particular times of the day, like a line gets drawn at market open and another line gets drawn at the top and bottom of the first minute candle?
it would be a great feature for customers and you can attract more open range traders to get bookmap, it is too difficult to draw and trade the opening with the way the market moves.
