Are there any stats on how many times a day an NYSE specialist does hybrid overrides?

Are there any stats on how many times a day an NYSE specialist does hybrid overrides?

This is where he can take the stock off of automated execution to deal with unusual situations.

Really depends on the stock.

I believe it happens pretty much every time when you see the slow quote indication on NYSE feed. I often see 1 lot quote marked as slow right after a print (due to LRP or a gap quote), and the very next quote would gap several cents (for small and mid-cap stocks).

You can easily calculate that stats if you have an access to hist tick data.

If there are any stats on this it might be on this page of NYSE stats?

otherwise is there a way to track it on a DDE sheet do you know of... or?

What software do you use for your tick data?

Also, could you give me an example of this situation so I can see what it looks like in my software... symbol, date, time? It would be greatly appreciated.

Thanks,

I use my custom-built software to produce the tape. Here is an example (BZH.N today):

[B]15:56:01  7.23 x 7.25  17 x 3  
15:56:02  7.23 x 7.25  17 x 1  F/F[/B]
15:56:03  7.23 x 7.30  17 x 2  
15:56:03  7.29 x 7.30  20 x 2  
15:56:03  7.28 x 7.29  20 x 19  
15:56:03  7.28 x 7.30  20 x 36  
15:56:03  7.28 x 7.30  19 x 36  
15:56:03  7.28 x 7.30  10 x 36  
15:56:03  7.27 x 7.30  49 x 36  
15:56:04  7.27 x 7.30  49 x 2  
[B]15:56:04  3s7.25  @ [/B]

3 lots were taken on the offer side (3s7.25), and there was Quote Gap (or maybe LRP) indicated by quote condition (F).
