Do all Markets have the same behaviour?

Indices yes, Forex depends because being a 24h market it's hard to identify a specific open and close and there might be a different liquidity for each of the 3 session: Asian , European and American. Same for commodities. I  don't trade Bitcoins so I'm not able to say.

I trade few non American indices and all the BPA concepts, including different times of the day , apply very well 

Thanks Fred, I'm in the UK so I'm likely to be trading the FTSE futures contract as it's in my Timezone, glad all the concepts apply here as well!

And e.g. in the EU session of Forex markets, do they sub-divide into the same Times of the Day concepts (ie, the Open and Close for Forex markets in the European session)

Cool, very interesting insights. I guess that's why a lot of traders tend to stick to one market, as they've gotten used to its behaviour over time!

So if I'm interested in the FTSE 100 Futures contract on the ICE exchange... and then I add the Volume indicator. What are the Open and Close for that contract on that exchange?

Price moves actively between 7am and 9pm (UK time), but looking at Volume and there are spikes at 8am and at 4:30pm. Perhaps this is related to the trading hours of the underlying?

It seems like trading hours for the Futures contract are 7am - 4:30pm perhaps, am I right? Or wrong?

I'm trying to get this right so I know when exactly the Open and the Close are...and also I want to get my Bar Counting to start / end at the correct times.

This is yesterday's trading...

Thanks!

And just to confirm, the Open and Close for the Emini although traded on the CME would follow the trading hours of the underlying's stocks traded on the NYSE: 9:30am - 4pm ET?

Thanks a lot
