Debt securities, securitized asset and income backed debt securities, lease certificates, liquidity bills issued by the Central Bank of the Republic of Turkey and other securities which are approved by Borsa İstanbul Board, all of which can be issued in Turkish Lira (TRY) or foreign currency can trade on this Market.
Takasbank acts as Central Counterparty (CCP) in all TL denominated Government Debt Securities and TL denominated securities issued by banks traded in the Outright Purchases and Sales Market.
Limit orders are placed by specifying price/yield and nominal value in multiples of a certain minimum order size. The non-executed part of the order remains passive in the system.
In this type of orders, a price/yield is not specified. The order given in multiples of a certain minimum order size is fully or partially matched by passive orders and the non-executed part of the order is cancelled.
The above order types can be given to include the specific conditions defined below:
Immediate or Cancel Order
It is an active order type subject to the condition of execution in part. As soon as it is entered, this order matches with the outstanding counter-orders, and its non-executed part is automatically cancelled. It may be given in the form of a “Limit Order” or a “Market Order”.
Fill or Kill Order
It is an active order type subject to the condition of execution in full. If this condition is not met as soon as the order is entered, the order is cancelled. It may be placed in the form of a “Limit Order” or a “Market Order”.
Validity Periods of Orders
Orders are valid for the day on which they are placed. All orders with the same value date are cancelled at 14.00 hrs unless executed, and those with a future value date are cancelled at the market closing hour.
Trading orders are transmitted in the currency of issue of the security over a price base of 100 units.
Clean price is the price of a security excluding the accrued interest or accrued lease during the coupon period, whereas dirty price is the price of a security including the accrued interest or accrued lease. Accrued interest or accrued lease is the amount of the coupon interest or lease that falls onto the number of days from the first issue date in the first coupon period, or from the coupon due date in other coupon periods, up to the settlement date. Settlement price is the price that is used in calculating the settlement amount of the trade, and is calculated with reference to the inflation coefficient for inflation-indexed Government Bonds. For other securities, it is equal to the dirty price.
In addition to order types described above, trade reports can be sent by specifying the nominal amount, price/yield, value date and capital market instrument to be traded. Sent trade reports can only be seen by counterparty member of the trade report. Trade reports can only be sent in capital market instruments issued by the Central Bank of the Republic of Turkey, Treasury, asset leasing companies founded by the Treasury and asset leasing companies founded by public enterprises assigned by the Treasury.
Order Matching Rules
In the market orders are matched using the “multiple price-continuous auction" method. The matching of two counter orders in the Outright Purchases and Sales Market is enabled through giving priority to the highest price in purchase and the lowest price in sale. If orders have the same price, time priority is applied.
In addition to matching of orders with equal prices, two counter orders are matched when a sell order with a lower price than the price of the existing buy order is received, or when a buy order with a higher price than the price of the sell order is received. Where price equality does not exist, the price of the order entered in the system earlier is the trading price.
Order Entry Methods
Orders are transmitted over a certain price type or yield determined by Borsa İstanbul for each security.
a) Securities for which orders are entered by simple yield;
Discounted securities issued in TRY/ Foreign Currency and stripped principals of coupon-bearing bonds (except CPI-indexed bonds),
b) Securities for which orders are entered by clean price;
Flat-rate bonds and lease certificates payable in TRY/foreign currency and floating-rate bonds payable in TRY with fixed first coupon rates (Clean price net of inflation is used for CPI-indexed Government Bonds which have been issued by the Treasury since February 2007)
c) Securities for which orders are entered by dirty price;
Stripped coupons of coupon-bearing bonds, and floating-rate TRY/foreign currency bonds, the first coupon rates of which are not fixed (Dirty price net of inflation is used for the stripped coupons and principals of the CPI-indexed Government Bonds which have been issued by the Treasury since February 2007).
The price field found in the trading system and the bulletins indicates the clean or dirty price which has been chosen at the time of entry of the order. For each security, in addition to the price, settlement price and if any accrued interest or accrued lease are also announced.
Price and Yield Ticks
A tick of TRY 0.001 applies to orders transmitted over clean or dirty price in the market while a tick of 0.01% applies to orders transmitted over yield.
Unmatched orders and unexecuted parts of matched orders transmitted to the market can be changed.
While the change in the price/return of the order, increase in nominal value and change of account holder of the trade lead to the loss of time priority, the reduction of nominal amount and change in representative reference do not give rise to the loss of time priority.
Unmatched orders and the unexecuted part of matched orders transmitted to the market can be canceled.
Orders are transmitted in the minimum order size and its multiples relative to the nominal values of the securities underlying the trade. On the Outright Purchases and Sales Market, orders with a nominal value below TRY 500,000 are traded on the Small Orders Market.

Under the “Market Making" system introduced by the Undersecretariat of Treasury, since September 2, 2002 for the purpose of enhancing effectiveness in the issue of government debt securities and secondary market transactions, market makers place purchase and sale orders that meet certain conditions with regards to quantity and spread for benchmark securities determined by the Undersecretariat of Treasury in accordance with the current rules of Borsa İstanbul Debt Securities Market. If orders placed within the determined quantity and spread range are the best orders, they are reflected to the market screen. Additionally, market maker orders are announced with the market maker code on pages designed by data distribution firms, aside from the current broadcast pages of the market.
Market makers transmit a buy and a sell order for each benchmark security as the market maker. Market makers place orders using Borsa İstanbul Debt Securities Market trading terminals. Market maker orders as well as other orders are transmitted to the Debt Securities Market Outright Purchases and Sales Market, and are processed according to price and time priority subject to the current operating rules of that market.
Market making banks are announced to public by Republic of Turkey Ministry of Treasury and Finance.
