How can I identify iceberg orders in equity markets?
How can I identify iceberg orders in equity markets?
Just use tag 111 (MaxFloor) together with the usual tag 38 (OrderQty)
in NewOrderSingle messages.
MaxFloor=100
OrderQty=1000
will show a quantity of 100 in order book, which is refilled on every match until the OrderQty of 1000 is exhausted.
HTH, Jörg
Thanks. I am on the buy side. So I would have to subscribe to L2 data and then monitor these two tags ?

Hmmm, please elaborate what you mean by “L2 data”?
As buy side, you would send these orders, as sell side receive them.
What exactly do you want to accomplish?

I meant Level-2 data. top 5 bids and asks from the order book.
Basically, I am trying to identify any iceberg orders in the market(say TSX) by any market participant and notifying trader to take appropriate action.

Bill,
Even if you subscribe to L-2 data, I am not sure its gonna help you in knowing whether there’s an iceberg order. The speciality of an iceberg order is that its hidden from the Exchange order book and lies within the market participants system. The moment first lot of total order qty gets executed only then the next lot is released by the market participant. I will appreciate if anyone could correct this if my understanding on iceberg orders is incorrect.
What Jorg suggested you was on how to send an iceberg order and not how to identify an iceberg order.

I beleive order is sent to exchange and a specific tag and a “display size” is set that indicates order is an iceberg. Exchange then breaks the iceberg order into smaller orders with size = “dislplay size” and add them on by one in the book. Such broken down orders have some special tags/values that can help identify if the order is an icerberg.

Usually if tag 111 MaxFloor is set alongwith the order then the order is considered as Iceberg order.

If I get filled by an iceberg order then do you think the 111 tag would be set in the fill execution report?

Yes, tag 111 is set in the execution report (ack as well as fills).

I am getting confused after reading all the transcripts, Please let me know when an order with tag 111 set(as an iceberg order) is sent by a buy side to sell side then to exchange where does this lie and how does this get executed?
Is it that the exchange receives it the same way as sent by buy side with tag 111 and then it works on the order. Consider an ideal situation where there is no touch at sell side.
