Ask and Bid in the Share Market

Bid and ask prices help you understand the prices at which buyers and sellers are currently willing to trade a stock or security. The difference between these prices is called the bid-ask spread, which can also provide an indication of the security's liquidity.

• The bid price is the highest price a buyer is willing to pay for a security.
• The ask price is the lowest price a seller is willing to accept.
• If the bid price is ₹50 and the ask price is ₹51, the bid-ask spread is ₹1.
• A narrower bid-ask spread generally makes it easier for buyers and sellers to reach a matching price.
• A wider spread can make it more difficult to buy or sell a security at the preferred price.
• You can consider bid and ask prices, trading volume, and the spread before placing an order.
• Limit orders can help you set the price at which you are willing to buy or sell.
   

The bid price is the highest price that a buyer is currently willing to pay for a stock or security. The ask price is the lowest price at which a seller is willing to sell that stock or security.
In simple words, the bid comes from the buyer, while the ask comes from the seller.
For example, suppose a buyer is willing to pay up to ₹100 for a share, while a seller is willing to sell it for at least ₹102. Here, ₹100 is the bid price and ₹102 is the ask price.
A trade can take place when the price offered by a buyer matches a price that a seller is willing to accept. Similarly, a seller can execute a trade by agreeing to the highest available bid price.
You can usually see the current bid and ask prices of a security on the trading platform provided by your stockbroker. These prices may keep changing as buyers and sellers place, modify, or remove their orders.
Bid and ask prices are therefore useful for understanding the prices currently available in the market rather than relying only on the last traded price.
 

An example can make the meaning of bid and ask prices easier to understand.

Suppose the current prices of a stock are:

• Bid price ₹50

• Ask price ₹51

  
  

Now assume you want to buy 100 shares. The lowest price at which a seller is currently willing to sell is ₹51 per share. Therefore, ₹51 is the relevant ask price for your purchase.

If you instead want to sell 100 shares, the highest price a buyer is currently willing to pay is ₹50 per share. Therefore, ₹50 is the relevant bid price for your sale.

This means a buyer who wants immediate execution may have to accept the available ask price. A seller looking for immediate execution may have to accept the available bid price.

However, you do not always have to accept the currently available price. You may choose to place an order at another price and wait for a matching buyer or seller.

For example, if the ask is ₹51 but you only want to buy at ₹50, you can place your order at ₹50. The order will be executed only if a seller becomes willing to sell at that price.

This is why some trades are executed quickly while others remain pending. Execution depends on whether a suitable buy and sell price can be matched in the market.

The bid-ask spread is the difference between the ask price and the bid price of a stock or security.

You can calculate it using this formula:

Bid-ask spread = Ask price − Bid price

Consider the earlier example:

• Ask price ₹51
• Bid price ₹50

• Bid-ask spread ₹1

  
  

The difference between the buyer's highest offer and the seller's lowest asking price is therefore ₹1.

A narrow bid-ask spread means the prices offered by buyers and sellers are relatively close to each other. This can make it easier for an order to find a matching price.

For example, a bid of ₹50 and an ask of ₹51 have a spread of ₹1. Buyers and sellers only need to bridge a small price gap.

Now suppose the bid price is ₹50, but the ask price is ₹60. The spread becomes ₹10.

In this situation, the difference between what buyers want to pay and what sellers want to receive is much wider. It may therefore become harder for both sides to agree on a price.

The bid-ask spread can also give you an idea of the liquidity of a security. A smaller spread generally indicates that buyers and sellers are closer in their price expectations.

A wider spread can make it more difficult to enter or exit a position at the price you prefer. Depending on the size of the spread and the availability of buyers and sellers, the security may be less liquid.

Bid and ask prices can help you understand the price at which your order may be executed. They can also help you assess the difference between the buying and selling prices before placing an order.
Here are some points you can consider while using bid and ask prices in your trading decisions.

• Avoid opening a position without first checking the bid-ask spread, especially when the gap between the two prices is wide.
• If you want a buy order to execute quickly, you may need to match the prevailing ask price.
• If you want a sell order to execute quickly, you may need to match the prevailing bid price.
• Use a limit order when you want more control over the price at which you buy or sell.
• Check trading volume along with the bid-ask spread to understand the liquidity of the security better.

For example, suppose the ask price of a share is ₹105, but you only want to buy it at ₹103. You can place a limit buy order at ₹103 instead of immediately accepting ₹105.
Your order will remain pending until a seller is willing to sell at ₹103. If no seller agrees to that price, the order may remain unfulfilled.
The same idea applies while selling. If the current bid is ₹100 but you only want to sell at ₹102, you can place a limit sell order at ₹102 and wait for a buyer willing to pay that amount.
This gives you more control over the execution price. However, it also means that the trade may not be completed if the market does not reach your chosen price.
Looking at trading volume can provide additional context. If there are many buyers and sellers participating in a security, matching an order may generally be easier than when trading activity is limited.
Therefore, the bid price, ask price, spread, and trading volume can be considered together when understanding how easily a security may be bought or sold.
 

Bid and ask prices help you understand the prices buyers and sellers are currently willing to accept in the share market. The bid is the highest buying price, while the ask is the lowest selling price. Their difference is called the bid-ask spread. A narrower spread generally indicates better liquidity, while a wider spread can make trade execution more difficult. Checking bid and ask prices, the spread, and trading volume before placing an order can help you make more informed trading decisions.
