What is the scaling of "Size" in T&S

[jgr]

What is the scaling of the "Size" value in T&S. Is 200 multiplied by 100 for 20,000 shares?

Also of the Bid and Ask that is say "506X388"?

Trade sizes are actual values. Bid and ask prices are presented in "hundreds" i.e. 10x10 means 1000 x 1000. If you use our KB, you'll find lots of information that will help you get a quick answer.

Thanks.

I did actually try to find this in the KB and it was not clear. That is why I asked. Still not clear. On the market depth display, there are a lot of sizes of 100, 200 etc. On another system I have, those are multiplied by 100. I would not expect 100 share trades to show up as separate line items but instead lumped together.

Hi,

Thanks for looking in the KB and for your additional questions.

We don't combine trades in our feed so you will see each transaction as it was fed from the exchange. If you want to post an example of what you're referring to, we'd be happy to review further.

Thanks.

Here is the image.

Question is the scaling of HSize and Size columns. Are those shares or shares divided by a scale factor of say 10 or 100?

BTW, I have to photoshop these images to get them down to size you require. Many if not most forum packages, scale images down to web resolution automatically on upload.

Hsize means Histogram size and is simply a copy of the bsize and asize columns. The Hsize columm also includes a histogram as a graphical comparison to the other sizes and it too represents multiples of 100.

Thanks.

So then, does 300 in the "Size" column mean that 30000 shares were traded then?

[ScottJ]

Not "traded" just quoted. Last sale transactions (i.e. trade sizes) are actual values where bid and ask sizes are presented as multiples of 100.

Thanks.

The column labeled "Size" in in the time and sales "ticker" section, in my case is for actual trades as I have checked checked Display "Trade" in the properties.

It is curious then that today, AIG which went up 23% with 47 Million shares traded, was trading mostly Size of 100. This would mean that we had a lot of small day traders participating or else some computer trading was driving a lot of small transactions for some reason.

AIG was pretty active today, I agree. To get a sense of sizes, I filtered T&S for blocks of 1000 shares or higher and looked at the last hour of the day plus after-hours trading. I then exported it into excel and totalled it up. In just that lone time period, my condition was met over 4600 times, totalling 9.1m shares. Heavy day indeed.

Not sure where you're seeing 47m traded today. Looks more like 115m shares today. That's more than double the 25day Vol avg (53m). AIG is all over the various volume hot lists for today as well.

Thanks.
