Trading and Registration

Registration, cancellation and query of client and own orders.

Secondary trading
Secondary trading includes all transactions that occur between investors after assets have been initially issued and sold in the primary market. Secondary trading can occur in different segments:
Bilateral Trading
SENEBI
Bilateral Negotiation Segment
Brokers operate on their own account, arranging transactions through direct dealings with their counterparties. All transactions arranged are reported by BYMA members for disclosure, registration and publication. The transactions arranged and registered on SENEBI are considered unsecured and, consequently, are not secured by Mandatory Default Fund established by BYMA.
SISTACO
Member Communication System
It is the system that allows Securities Brokers (ACVN) to report to BYMA activity on securities. The ACVNs are responsible for finding counterparties for transactions between members, and act as guarantors of the same bilateral trades they are intermediaries for, which will be subsequently registered in the Price-Time Priority segment. In the event that the trades registered on SISTACO by ACVNs are not guaranteed, they must be registered on SENEBI.

Price-Time Priority (PPT)
This is electronic trading with automatic trade matching through the Millennium trading system, in which the price-time priority (PPT) rule governs order precedence.
This means that the orders that will execute first will be those with the most convenient price and, for all orders with the same price, those that have been entered first.
This segment of the market is called "blind" because the counterparty to the trades is not known. The settlement of these trades is guaranteed by BYMA fulfilling its role as central counterparty.
