A stock has been pressing against ₹418 for half an hour. Each time the offer there is taken, another 2,000 shares appear at the same price within a second, and it has now happened eleven times. The obvious reading is that somebody is defending the level with conviction. The likelier reading is that one order for 40,000 shares was entered with a disclosed quantity of 2,000, and the exchange has been refreshing it automatically all along, with no human involved after the first click.
A grain merchant keeps ten kilos on the counter and forty sacks in the back room. Every time the ten kilos go, a boy refills the counter from behind. To a customer walking past, the shop appears to have ten kilos and infinite patience. To the merchant, it is one consignment being sold in a way that does not advertise its size.
Disclosed quantity is that counter, and in India it is a feature of the exchange itself rather than a trick played by a broker. What replenishes is not a decision each time. It is one order, releasing itself in slices.
What five levels actually are
- A snapshot, not an event stream. Retail feeds deliver the state of the book at intervals. Between two snapshots, orders were placed, modified and cancelled, and you saw none of it. Sequence-based reading — which side hit first, how fast the queue drained — needs a feed that most retail terminals do not carry.
- Five of a deeper broadcast. The exchanges disseminate more depth than the five levels a typical app draws. Whether you can see it depends on your data subscription, not on the market being secretive.
- Quantity and a count. Each level carries the aggregate quantity and the number of orders composing it. The count is free information that is almost universally ignored.
- Aggregate totals at the foot. Total buy quantity against total sell quantity across the visible book is the number retail traders over-read most enthusiastically, since both sides can be withdrawn instantly and routinely are.
Disclosed quantity, and why the queue matters
- 1The order is entered with two numbers
A total quantity, and a smaller disclosed quantity that the book will show. The exchange sets a minimum proportion that must be disclosed — the specification is published and has been revised over the years, so read the current one rather than a remembered figure.
- 2Only the disclosed slice is visible
The book shows the slice. Nothing in the depth window distinguishes it from an ordinary order of that size, which is precisely the point.
- 3When the slice fills, the next one is released
The exchange automatically posts the next tranche at the same price, without any further action by the trader. This is what produces the level that keeps coming back.
- 4Each new tranche joins the back of the queue
This is the part that matters and the part nobody mentions. Under price-time priority, a refreshed slice has a fresh timestamp, so it queues behind every order already resting at that price. Concealment is paid for in position.
Why the Indian book flickers less than a foreign one
Anyone who has watched a United States depth ladder is used to quotes appearing and vanishing many times a second. Indian books are visibly calmer, and part of the reason is a charge rather than a market preference. Exchanges here operate an order-to-trade ratio framework: a member who places a very large number of orders relative to the trades they actually complete pays for it, with orders far away from the market weighted more heavily than orders close to it.
- Placing and cancelling thousands of orders to probe the book
- Resting large decorative orders far from the market that were never meant to fill
- Quote stuffing designed to slow other participants down
- The purely mechanical part of spoofing, which is separately a market-abuse matter
- Stop a determined participant from placing one large order and pulling it
- Make visible depth a commitment — resting orders remain intentions everywhere
- Prevent algorithms from working orders; it prices the behaviour rather than banning it
- Apply to you directly — it is levied on the trading member, not on a retail client
The band that cuts the book off
The single most Indian feature of the order book is that it is truncated. Orders outside the permitted range for that security are simply not accepted, so the depth window can show you empty levels above a price that mean nothing about supply and everything about the rulebook.
| Mechanism | What it does | What it does to the book you see |
|---|---|---|
| Fixed price band | A daily percentage limit around the previous close, applied to many securities without listed derivatives | No order can exist beyond it. The book ends at the band, and near it the remaining depth thins for reasons unconnected to interest in the stock |
| Dynamic price band, or operating range | A flexible range around a reference price, applied to derivatives and to securities without a fixed band. Orders beyond it are rejected, and the exchange widens it in steps after a cooling-off period once there is genuine two-way interest at the boundary | A fast move can hit the edge and pause, not because buyers stopped but because the range has to be flexed first. Volume dries up for a few minutes in a way that reads on the chart as exhaustion |
| Trade-to-trade and surveillance bands | Narrow bands, often 5% or 2%, applied to securities under a surveillance framework | A book that can barely move. Absorption, exhaustion and breakout language all lose their meaning inside a 2% range |
A level refills with the same quantity nine times in ten minutes. What is the most defensible conclusion?
Dukaandaar counter pe das kilo rakhta hai, peeche chaalis bori. Das kilo bike, ladka phir se das kilo rakh deta hai. Aap bahar khade soch rahe ho "banda ade hue hai, bhaav nahi girega" — banda ada nahi hai, ek hi badi order slice mein nikal rahi hai. Aur haan, jab bori khatam hoti hai toh counter ek jhatke mein khaali ho jaata hai, bina bataye.
- Retail depth is a periodic snapshot of five levels of a deeper broadcast, not an event-by-event stream.
- Disclosed quantity is an exchange-native order attribute; each refreshed slice goes to the back of the queue.
- A level that keeps refilling shows size being worked, not conviction that the level will hold.
- Order-to-trade charges price quote flickering, which is why Indian books look calmer than foreign ones.
- Price bands truncate the book — an empty side near the limit is missing permission, not missing sellers.

Common questions
Short, direct answers to what people ask about this topic.
- disclosed quantity meaning in share market
- Disclosed quantity is an order attribute on the Indian exchanges that lets a large order display only a smaller slice of itself in the order book. When the visible slice is filled, the exchange automatically releases the next tranche at the same price without any further action by the trader, which is why a level can appear to refill again and again with nobody deciding each time. The exchange sets a minimum proportion of the total that must be disclosed, and that specification has been revised over the years, so read the current one rather than a remembered figure.
- an order that shows only part of its total quantity in the book is called
- A disclosed-quantity order in Indian exchange terminology, and an iceberg order in the imported vocabulary. The difference matters at the queue: disclosed quantity is native to the exchange order specification and refreshes one order, while the iceberg products several Indian brokers offer slice a parent order into a series of separate child orders that can also be re-priced. From the depth window you cannot tell which of the two is replenishing a level.
- how many levels of market depth can you see on an indian trading terminal
- Most retail terminals draw five levels on each side, each showing the aggregate quantity and the number of orders making it up. The exchanges broadcast more depth than that, so seeing beyond five is a question of your data subscription rather than of the market withholding anything. What no depth setting gives you here is participant identity, because the Indian order book is anonymous by design.
- why does the same quantity keep reappearing at one price in the order book
- Almost always because one large order is being worked at that price through disclosed quantity or a broker slicing engine, with a fresh tranche released each time the visible slice is taken. That is evidence size is present, not evidence the price will hold — and since each refreshed slice carries a new timestamp it joins the back of the price-time queue, so concealment is being paid for in priority. When the parent order is finished the level typically disappears at once, with no warning in the book.
- what happens if you place an order outside the price band
- It is rejected outright and never enters the book. Securities with a fixed daily band cannot trade beyond that percentage of the previous close, while securities with listed derivatives sit inside a dynamic price band, or operating range, that the exchange widens in steps after a cooling-off period once there is genuine two-way interest at the boundary. This is why an empty offer side near the limit can mean an absence of permission rather than an absence of sellers.
