Limit orders vs market orders on UZSE

When you ask your broker to buy or sell a share on the Republican Stock Exchange «Toshkent» (UZSE), you choose an order type. UZSE has two basic types: the limit order and the market order (trading system structure, as of 26 September 2026). The choice decides what you control: the price or the certainty of a trade. On a market where many shares trade only a few times a day, that choice matters more than it seems.

The limit order: you set the worst price you accept

A limit order names the security, the quantity and a price. For a buy order, the price is the most you are willing to pay. For a sell order, it is the least you are willing to accept. UZSE's own example: a buy limit order at 40,000 UZS can trade at 40,000 UZS or lower, and a sell limit order at 40,000 UZS can trade at 40,000 UZS or higher.

What you get:

• Price control. You never pay more (or receive less) than your limit.
• No guarantee of a trade. If nobody is willing to trade at your price, the order simply waits in the order book, and it may never fill.
• Partial fills. If only some sellers meet your price, you may buy part of the quantity and wait for the rest.

Limit orders are accepted on every UZSE board, including the negotiated boards, where they are the only type allowed (order execution procedure, as of 26 September 2026).

The market order: you set the quantity, the market sets the price

A market order names the security and the quantity, but no price. It asks for a trade now, at the best prices available. UZSE accepts market orders on the main boards for shares, bonds and a few other instruments. The exchange warns in plain words that market orders do not guarantee a price.

How does the trading system decide the price of an order that has none? The exchange's order execution procedure treats a market buy order as if it were priced high enough to meet the cheapest sellers waiting in the book, and keeps it trading against the next cheapest sellers until the whole quantity is filled. A market sell order works the same way in reverse, against the highest bids. Two limits still apply:

• The price can never go beyond the day's price limit, which is 20% above or below the reference price (normally the previous day's close).
• If there are no opposite limit orders at all, the market order is priced off the most recent trade price.

In practice, a market order buys from the best offer, then the next one, and so on. That is fine when the order book is deep. It can be expensive when it is thin.

A worked example

The numbers below are illustrative, not taken from a real share. Suppose the sell side of the order book for a share looks like this:

• 100 shares offered at 10,050 UZS
• 150 shares offered at 10,200 UZS
• 200 shares offered at 10,600 UZS

The last trade was at 10,000 UZS. You want 300 shares.

Market order for 300 shares. You buy 100 at 10,050, 150 at 10,200 and the remaining 50 at 10,600. The total is 1,005,000 + 1,530,000 + 530,000 = 3,065,000 UZS, an average of about 10,217 UZS per share, or about 2.2% above the last trade, before your broker's commission.

Limit order for 300 shares at 10,200 UZS. You buy 100 at 10,050 and 150 at 10,200 at once, which is 250 shares for 2,535,000 UZS. The remaining 50 shares wait in the book at 10,200 UZS. They fill only if a new seller arrives at 10,200 or below during the session.

Neither result is right or wrong. The market order bought everything but paid for the thin book. The limit order protected the price but left part of the order unfilled.

Rules that affect both order types

A few UZSE rules apply whichever type you choose (trading system structure, as of 26 September 2026):

• Pre-funding. Your broker can place a buy order only if 100% of the money is available, or a sell order only if 100% of the securities are. They are frozen once the order is placed.
• Tick size. A limit price has to fit the price step for its range. For shares priced from 10,000 to 50,000 UZS the step is 50 UZS, so a limit at 10,175 UZS is not valid, while 10,150 UZS is.
• Day validity. An order is valid only during the session of the day it reaches the trading system. Anything unfilled at the close is gone, and you place a new order the next day if you still want to trade.
• Changes. You can correct or cancel an order only while it is unfilled. A price change or a quantity increase resets its place in the time queue.
• Execution conditions. The exchange's order procedure also describes conditions such as fill-and-kill (fill what you can now, cancel the rest) and fill-or-kill (fill all at once or cancel). Ask your broker which conditions its terminal offers.

Why the choice matters on UZSE in particular

Trading activity differs enormously from share to share. On 25 September 2026, for example, UZSE recorded 89,015,258 shares of the National Investment Fund (ticker UZNF) changing hands in the day, while UzAuto Motors (UZMT) traded 79 shares (UZNF and UZMT on uzse.uz, as of 25 September 2026). In a share that trades a few dozen units a day, the gap between the best offer and the next one can be wide, and a market order can move the price against you. Read liquidity risk and thinly traded stocks for more on this.

The opening and closing auctions also change the picture. Orders collected from 09:30 all trade at one opening price at 10:00, and orders collected from 15:30 at one closing price at 16:00. A market order sent into an auction takes that single price, whatever it turns out to be. The day is described in UZSE trading hours and settlement.

When each type tends to fit

This is not advice on what to trade, only how the tools behave:

• A limit order suits shares with few trades or wide gaps between bids and offers, larger orders relative to normal volume, and any time you have a clear price in mind.
• A market order suits cases where getting the trade done today matters more than a small price difference, and the order book is deep compared with your order size.

Before either, look at the order book. With a free Finmind account, the market-wide order book shows the best bid and ask and the quantities on each side for every UZSE security with resting orders; order book, bid, ask and spread explains how to read it. Each share also has a public page, such as UZMT, with its recent daily closes. To practise both order types with virtual money at real prices, use the Finmind simulator described in the free portfolio simulator.
