Hello, I am trying to get all levels for previous day premarket, regular trading hours and post market. Can anyone help me with a thinkscript code for : Previous Day Premarket Open, Low, High, Close. (0400 to 0930)
Previous Day regular trading hours Open, Low, High, Close. (0930 to 1600)
Previous Day post market Open, Low, High, Close. (1600 to 2000)
Previous Day Open, Low, High, Close. (0400 to 2000)

there probably are several studies here, that have different parts of what you are asking for.
i decided to start fresh and make it.

it draws 3 sets of lines, on the current day, for the 3 time periods, on a previous day.
pre , regular, post times

can pick an offset, to pick a previous day.
input days_back_date = 1;

it draws 4 candles, after the last bar, to represent the 4 time periods

Code:
``````# prev_day_levels2_00

there probably are several studies here, that have different parts of what you are asking for.
i decided to start fresh and make it.

it draws 3 sets of lines, on the current day, for the 3 time periods, on a previous day.
pre , regular, post times

can pick an offset, to pick a previous day.
input days_back_date = 1;

it draws 4 candles, after the last bar, to represent the 4 time periods

Code:
``````# prev_day_levels2_00

#Previous Day Premarket Open, Low, High, Close. (0400 to 0930)
#Previous Day regular trading hours Open, Low, High, Close. (0930 to 1600)
#Previous Day post market Open, Low, High, Close. (1600 to 2000)
#Previous Day Open, Low, High, Close. (0400 to 2000)
