Can there be more Bid than Ask in a tick? - page 3

And again, even the part I think I understood - "What happens if two people delete their application at the same time?"

Man, I really don't understand what you're saying. I read it over 3 (three) times and I don't get it.

And once again asking you to clarify what you meant when you wrote "but then I rarely see tics when nothing changes" looks ridiculous of me

:) OK - let's go back. You wrote - that a tick is not what I... ("never mind that") . wrote. A -"a tick is a change in the "best price" " and then -"Not in a period. Now, in a given moment. And if an order is say 1 contract and its holder has deleted it, there will be a tick to the next price with the order, without the fact of buying or selling."


So, I understand that a tick is a change. Yes?


And in development a question - If a tick is simply a change, what happens if - "Two have deleted their orders ONCE"? So two bids were deleted - not one, but two at once. There are actually TWO "problems" at once - First - if you have a list, to keep its integrity you have to LOCK concurrent access to it, and allow only monopoly access, otherwise there will be a problem with definition of which record is now the last at the bottom ( or top ) ... which one is the best. If you remove one entry first, it becomes the best one from above, then another one from below, and the best one from below becomes the best one from below. If you remove two at once, then it turns out that which is the best is not clear.


And the second one - but this is more complicated "stuff" I will explain - well, if a tick is a CHANGE, that is, if we removed the best and then immediately added a better and even more exactly the same, then it turns out that nothing has changed? Here's the question - in what range of time should these two deletions occur, so that you don't see it as a tick?


You see how many questions are raised by accepting that a tick is a change.

There is no question about it. You have to read somewhere about how exchange trading works. I'll pass.

If you answer the question, no, bid cannot be higher than ask. There is an exchange software and rules for satisfying and placing orders. This is in theory.

In practice, there is a fuel exchange in St. Petersburg. Putin recommended that part of the trading be done there. Without any obligations, for now.

There you can make a deal between the seller and the buyer at any price you want. The price will of course be fixed.

But it will have nothing to do with current market prices. The scheme historically evolved as buy-sell at an undervalued price with cash refund of the difference.

Now you have to go through the stock exchange? No problem. The owners of the exchange and customers of exchange software are big sellers and bidders. Eventually they will get to it, of course. Or maybe))

OK - to summarise - you're probably just quoting someone else without getting into the gist of things. But no problem, some people need it and some people don't.
 

Your failure to explain what you meant when you wrote "but then I rarely but occasionally see tics when nothing changes" remains a serious mystery.

Instead of "but then" you obviously meant "sometimes". But that's not important. I wonder exactly what you see on the screen. What exactly does not change at the time of the tic? and how do you determine that there is a tic?

It seems to me that our discussion with you is not constructive, does it make sense to continue. I don't think so. What do I see? Have you never seen the tick data on forex, not as a chart but as a data? If no - then perhaps that's why we do not understand each other. What I see - well, two ticks in the database with different times and the same prices.

In practice, for example, there is a fuel exchange in St Petersburg. Putin has recommended that part of the trading should take place there. It is not compulsory yet.

In this way, it is possible to make a deal there at any price between the buyer and the seller who have agreed in advance. The price will of course be fixed.

But it will have nothing to do with current market prices. The scheme historically evolved as buy-sell at an undervalued price with cash refund of the difference.

So such a transaction is a violation of the law. The fact that it is possible in Russia is apparently so far. What you have cited as an example is a serious breach; in the USA, for example, you can go to prison for a long time. In Russia, as time goes by, it will also (yes, already) become clear that trading by the rules is a kind of ideology. If it is violated, it will not be capitalism but something else. But let us move away from politics without getting too close. But let's talk about politics without getting too close. OK?

And the bid is higher than the ask at a particular time? let's look at it together.
 
Mischek:
And bid above ask at a specific time ? let's see together .

Yes, of course. I didn't ask for nothing. :)


Look at ? Well here it is -

And there have been a total of 3862 such ticks since 2006.

Since 2006 there were 3862 such ticks in total.

Maybe there are some peculiarities of conducting deals, glitches, etc.

Roughly, it happens three times a day. It cannot be of practical use. It does not destroy the basics of exchange trading, is there any point in searching for reasons for this nonsense?
