How do the enveloping strategy fares in HYBRID?
There is a new fee structure which will charge fees for NYSE orders when the ratio of order cancellation vs Fill > 90%.
Dont know if you are aware of this.
I believe the NYSE is discouraging this kind of practice (ENVELOPING). However, I cannot understand why they would also count IOC order that gets cancelled. Because this is a legitimate order that doesnt recieve fill. Therefore it should not be counted as cancelled orders.
Dnajos:eek:
We have cancellation fees in the options markets. The reason for the fees was given as data capacity constraints. Now we discover that options will be priced in pennies (starting this month). Option exchange disseminated data will increase significantly. No capacity constraints were mentioned for this change.
NYSE cancel fees are also a method for confiscating trader profits. The NYSE bragged about it's ability to handle data, in its attempt to attract some of the algo business.
Contact a lawyer. It's an interesting question - can an exchange change it's rules simply to discourage profitable trading. One thing's for sure - they'll keep trying discriminatory rules and fees if you don't challenge them.
