Here's a look at recent intra-day seasonality!

Could you explain this any further?

I assume that the curves on the chart represent average values over a defined period.

Isn't this the same topic as here:

Intraday Seasonality Volatility - When to Trade and When Not to Trade Specific Trading Times Each instrument has its specific times, when it can be traded, and also has its times, when trading does not pay off. The question is. how to determine the optimal trading times? The main criterion is volatility. If volatility …

In which case lets use the first existing thread instead to prevent a split topic, and this one can be closed.

It is at least similar. The other thread was focused on volume and range analysis, not on the seasonality of price changes.

Interesting way of looking at things. Its interesting how strong the closing period was during the whole period, and how weak the 1:30 to 3:00 period was. There might be some relationships here that would be useful in building an intraday trading system.

Its not quite the same as the other intraday seasonality thread, though. That one was looking at volatility whereas the chart above is looking at directional movement.

Yes, intra-day data is collected over custom time intervals on a 15 min. and then superimposed on the daily.

Yes, but how many days do they use as a lookback period?

As there is a starting point in 2003, it is cumulated over 8 years. This information is not very useful, as it does not show the trend in recent years. It would make much more sense

- to take a rolling period of 100 days to look how the directional movement of each segment play out
- or take a rolling period of 1 year and make an analysis for each day of the week

I think that this can easily be achieved with a small indicator.
