I was wondering where all the shares came from on offer for the AH trading last night. This may all be typical trading, and let me preface that I am not well versed in trading, but in case any of this is unusual, here is what I found. All of this is probably nothing out of the ordinary.
It looks like most were NDD transactions and some NSD transactions.
No dealing desk (NDD) brokers allow access to the interbank market without passing through local dealing desk. With these brokers a no re-quotes on orders and no order confirmation is possible. No Dealing Desk brokers are either STP or ECN+STP. The differance between the two is that STP (Straight Through Processing) brokers send orders directly from clients to the liquidity providers and ECN (Electronic Communications Network) forex brokers additionally allow client orders to interact with other clients' orders.
The only reference I found in a quick search was that NSD was a Russian platform. I am probably really way off base on this, so someone please correct me.
"Table 1 lists the required fields when settling in Russia (NSD)"
A few were EDGX which is not unusual.
Here is a partial list of AH trades and the markets.
