What is Market Depth in the Stock Market?

Market depth refers to the extent to which a market can absorb large buy or sell orders without a significant price change. It is a measure of liquidity since it demonstrates the volume of buy and sell orders at various price levels for a particular stock.

Let's say you are ready to buy 1,000 shares of some company. If the market has a high depth, your order will likely be filled without increasing the price. For example, if the market has low depth, your order could move the price sharply, even if small. This idea is fundamental to understanding when trading on the NSE because in-depth data is readily available to help you decide if you want to make a trade.

Decoding the Market Depth Chart

The market depth chart, often called the order book, is your way into this data. An order book displays all the buy (bid) and sell (ask) orders pending for a stock at various price levels. The bid side displays the prices and quantities buyers are willing to pay for a stock, while the ask side displays what sellers are willing to sell their stock for. The bid-ask spread is the difference between the highest and lowest bids and is an essential market liquidity measure.

For instance, looking at the NSE market depth for a stock, you might locate 5,000 shares being bid for at ₹100 and 3,000 shares offered at ₹101. You can see significant buying interest at ₹100, but less selling interest at ₹101, which represents a potential stabilising feature for the price (if demand persists). By examining the depth of the market indicator, you can determine whether an asset's liquidity is sufficient to accommodate your specific trading plan.

How to Read Market Depth

Once you know how to read an order book, understanding how to read market depth is relatively straightforward. Here's a three-step process:

1. Examine the Bid-Ask Spread: The narrower the spread, the better it is to trade at a price close to the current market price; the wider the spread, the less liquid it is and the greater the chance of increased trading costs.

2. Analyse the Number of Orders: Examine the number of shares at each price level and the volume of orders at certain price levels (large orders represent support for bids and resistance for asks).

3. Observe Order Flow: A bullish trend may begin if there are more buy orders than sell orders in the order flow. Alternatively, a bearish trend may begin if selling pressure is heavy.

4. Monitor Changes: Analysing market depth involves tracking the changes in the order book. If there is a sharp increase in buy orders or a spike in sell orders, this could indicate significant price volatility shortly.

You can access this data via your trading platform and should typically see real-time market depth updates through the NSE. The more you monitor market depth, the more familiar you will be with ebbs and flows in market pricing.

Many factors impact depth on the NSE:

• Trading Volume: Stocks with high trading volumes generally have deeper markets.

• Market Makers: Market makers place orders on both buy and sell sides to enhance liquidity and improve market depth.

• Market Conditions: A stock with a widespread during volatile conditions, for instance, during earnings seasons, the depth may thin out as traders become slightly more conservative.

Practical Guidelines for Applying Market Depth

When applying market depth analysis:

• Utilise your trading platform tools to establish and visualise a real-time market depth chart.

• To validate your signal, look at depth and include other supportive indicators, such as volume and price trend information.

• To build confidence, practice looking at the order book by making small trades for practice or just looking at market depth and completing the transaction on your practice account.

• Be aware of sudden changes in depth. Typically, larger institutional orders or news are tied to the depth change.
