I didn't say no, but I'm confused by R. Feynman... He observed particles exactly at uniform intervals. He's kind of an authority for me :)))
Need specific quotes in 1 sec. Example:
12.00.00 - 1.22222
12.00.01 - 1.22224
12.00.02 - 1.22224
etc.
At the same time it is desirable (but not obligatory) to calculate the tick volumes for this second.
I need at least a draft - how to do it.
And I'm confused by the fact that you exclude quotes from consideration inside the 1 second interval. That is, most of the information. Well, you are a theorist - you know best))
What is the format of the archive, or send a piece of it - what to process.
And what confuses me is that you are dropping quotes from consideration within the 1sec interval. That is, most of the information. Well, you are a theorist - you know best))
What is the format of the archive?
File .csv
1 column - time
2 column - quote.
The most difficult moment - when there is no new quote, you still need to overwrite the previous one.
If you just have some code snippets - how to do it - leave them here, I'd be very grateful.
And we'll get to milliseconds - but we have to read evenly there too.

It's hard with theorists)) Pin a piece of the archive.
Any one. Whichever one you are interested in.

I'm not interested in forex archives. One last try.

Dimitri, have mercy on the old man (me)... Any absolutely archive from forex, from forts (I think you prefer USDRUB - well, let's look at it). The method must work everywhere, otherwise - to hell with it!

Some kind of strange 'donkey' stubbornness. Or your religion does not allow you to attach a piece of archive. You understand, that not to change ten times, it is better to make initially for the concrete format. Apparently, it is inaccessible for a theorist)).
Ok, I'll take my format for ruble/dollar, but it will be a complete application. And a little later - need to work, play with the players, so to speak)))
Well, it's a pity the main message wasn't heard.
Wait a minute, Dimitri - maybe you don't need to convert anything.
I am a theorist - don't forget! My flight of fancy interferes with my work, so to speak. Wait a minute - wait for my next post. It'll be brilliant, as always.
So, gentlemen traders, we continue to move towards the logical finale.
Once again I strongly recommend reading Shelepin (see attached file) - especially pages 9-10. In fact, the whole solution of the problem is presented there - all we need to do is to program it correctly.
Now to the practice.
Of course I was confused by the USDJPY trend last week.
This is how I calculated variance earlier:
For pseudo-Markov processes:
Dispersion S^2=c*t*l, where:
l - mean value of jumps
t - observation time
s - jump frequencies in time t (number of ticks)
By jumps we mean tick increments of price.
We have:
S^2 = (N/t)*t*mean(|Ask(t)-Ask(t-1)|) = N*mean(|Ask(t)-Ask(t-1)|)
Then the standard deviation of the process: S = sqrt(N*mean(|Ask(t)-Ask(t-1)|)), where N is the number of ticks in observation time t.
The text highlighted in red is a text that I obviously misunderstood from Shelepin.
