Mean posts per half-hour during the day

Caption

It represents mean posts per half-hour during a day, showing the intraday seasonality of message posted on stock forum. Intraday posting activities usually increase rapidly after the opening, decrease at lunch time and increase again before market close. This result is very similar to Renault (2017), which shows that the average number of messages during non-trading hours is lower than during trading hours.
