############################################################################This is based on 10 minute bars over the last year or so. Readers should read my last few previous posts for background.
The first set of results, EUR_USD, are what the charts of my previous posts were based on and include combined results of my "Delta Turning Point Filter" and "Normal Turning Point Filter" and the results for each filter separately. Since there doesn't appear to be significant differences between these, the other three pairs' results are the combined filter results only.
The K_opt variable is the optimal number of clusters (see my temporal-clustering-part-3 post for how "optimal" is decided) and the ix_values are also described in this post. For convenience the first set of ix_values per day have the relevant times anotated underneath and therefore it is a simple matter to count forwards/backwards in 10 minute increments to place times to the other ix_values. The variable n_bars is an input to the turning point filter functions and essentially indicates the lookback/lookforward period (n_bar == 2 would mean 2 x 10 minute periods) used for determining a local high/low according to each function's logic.
As to how to interpret this, a typical sequence of times per day might look like this:
18:40 22:00 1:30 5:00 8:30 12:00 15:30 18:50 22:00 1:30 5:10
where the highlighted times represent the BST times for the period covering the London session open to the New York session close for one day. The preceding and following times are the two "book-ending" Asian sessions.
Close inspection of these results reveals some surprising regularities. In even just the above single example (an actual copy and paste of a code box example) there appear to be definite times per day at which a local high/low occurs. I hopefully will be able to incorporate this into some type of chart for a nice visual presentation of the data.
More in due course. Enjoy.
