hi, i'm trying to do some order flow analysis. i'm curious if anyone has a way to get an average order size for a given instrument. most of these orders go so fast on time and sale. and what sucks even more is that, even if you can build an indicator to chart those orders.. to calc out average order size.. in NT.. that data disappears anytime you refresh the chart or restart NT. what i'm trying to do is look at only orders greater than X threshold. So to try to look at commercial players rather than retail players.. to see which direction they are trading etc. So it would be nice to get:
ES average order size =1 contract
NQ avg order size = 10 contracts
CL avg order size = 1
for the past.. 30 days etc. Where can i get this info?
Can you help answer these questions from other members on NexusFi?
Here you go, since beginning of this year. I've looked at this for several years now, it really doesn't change in a meaningful way. All the big boys use iceberg orders.

I understand what you are getting at here, but there's a sense in which the average (and only) order size on any exchange that permits partial fills of one contract units, will always be one.
If I place a 1 contract buy order now, and then another in five minutes time, are these the same order? You'd probably say that they're not, as there is a time lapse between them. But if I place a 2 contract buy order now, it is theoretically possible that my first contract will fill, then the market will trade at the bid for five minutes, and then my second contract will fill.
Even if my contracts fill one after another, there is a time-lapse between the two. The contracts in an order cannot fill simultaneously because they are queued, one after the other.
Given all this information, combined with the use of iceberg orders and all sorts of other clever disguise tactics, I think it might be unlikely that the average order size data you're looking for would be much help. Just my opinion though!
Are we talking about the average ORDER size, or the average TRADE size here?
Big Mike's data in this thread is actually for order size?

Average trade size is just the volume of the bar divided by the number of transactions (ticks) in that bar. Average order size is not something you would likely be able to calculate since huge numbers of orders are placed, and cancelled, at lightning speeds, relative to the number of completed trades.
For a tick bar chart calculating average trade size is trivially easy since the number of ticks per bar is constant.
For other types of bars:
In real time Ninjatrader 7 or 8 can easily do that, just count the number of bar updates per bar since each bar update corresponds to one completed trade.
For historical in Ninjatrader 7 add a secondary one tick dataseries and count how many times it fires per bar of the primary series.
For Ninjatrader 8 use the same code as for real time, but run the price series in tick replay mode.
