On the Myfxbook's account page, you can see the trading history along with their analytics when each column shows its related value (such as pips, duration, open time, close time, etc').
Next to the trade, you can see the trade's analytics. This chart shows a normalized progress curve of each trade as it happened (when possible to calculate). In other words, it is a small image showing the open and close points and the most profitable price will also be marked as a point on that image.
The 'Hourly' tab on the 'Advanced Statistics' chart is based on closed trades.
The 'Custom Analysis' > 'Timing' shows trades according to their open/close dates according to the option you've marked. This will show that calculated data on the custom date you've set.
For example, if you have set a custom date of 1 week (by clicking the 1W button) and also check the 'close' in the timing, the calculated data will be of all the trades that were closed during the custom period.
All the 'behind the scene' documentation that you're referring to is actually detailed on the Myfxbook account page itself.
