Hi there,

I’m looking to have a study take the closing price every 30minutes and print a horizontal line for the next 30min time period. Ideally the line would not extend for longer than each 30min segment. RTH for the current day only. Appreciate any help, cheers.

Try this

Ruby:
``````def agg   = AggregationPeriod.THIRTY_MIN;
def c     = close(period = agg)[1];

plot close_horizontal = if Between(GetTime(), RegularTradingStart(GetYYYYMMDD()), RegularTradingEnd(GetYYYYMMDD())) and GetDay() == GetLastDay() then c else Double.NaN;
close_horizontal.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);``````

SleepyZ, I wana say thanks for all the help you provide. This looks so good! I just put on a few winning scalps just based off this 30min risk level. Gives great structure to the price action. Thanks again.
