Have you ever wondered about the feature Auctions in your Zerodha Bids tab? In this post, I will explain everything about Auctions in Zerodha and how you can participate in auction markets on Zerodha Kite.

What are Auctions in Zerodha?

The auction market opens at 2:00 PM and lasts 30 minutes for short-delivered shares already settled in the Demat account. For now, Zerodha doesn't allow orders to be placed in the BSE's auction market. Fresh sellers of short-delivered shares can sell them to buyers during these 30 minutes. However, it's essential to remember that there is a circuit limit of 20% from the previous close. Besides, you can't buy shares in the auction market since the exchange is the buyer.

What are Bids and Offers in Auctions in Zerodha?

To participate in auctions in Zerodha, you must be clear about the Bid and Offer. While Bid is the price a buyer is willing to pay for a share, Offer is the price a seller is willing to sell a share. Zerodha auctions will display five bids and five offers.

A bid is the highest price a ‘buyer' is willing to pay for a share. Offer is the lowest price a ‘seller' is willing to sell a share. After you click ‘Market Depth,' Zerodha will show the five highest buyer bids. And five offers from sellers. The seller with the lowest Offer will have a high chance of winning.

What is short delivery?

A short delivery occurs when a trader short-sells a stock but fails to buy it or close the short position because of illiquidity or stocks hitting the upper circuit. After a short delivery, the shares will be credited on T+2 days after an attempt to procure the short-delivered shares at an auction on T+1 days. If the exchange can't procure the shares in the auction, it will credit the cash to the user's Zerodha account based on the close-out price.

How are transactions in auctions in Zerodha settled?

The settlement takes T+1 days in the auction market. 80% of the funds will be transferred immediately, while the remaining 20% will be blocked as a delivery margin and will be made available on the next trading day.
