Pre-open session of NSE & BSE-How it actually works?

You may have watched on business news channels a pre-open session for NSE and BSE from 9.00 AM to 9.15 AM during market days. But you actually know how your placed orders are executed during this session? It is very interesting and must know factor for all who are interested to invest in stocks.

Before we proceed let us look for the types of orders you can place in market. Their are two types of order placing methods. 1) Market orders-These are the orders where you have not specified any price while buying or selling. Hence such orders execute as per the availing market rates. 2) Limit orders-These are the orders where you have specified the price and quantity for buying or selling. These get executed once find the matching orders.

Pre-open session as I told above starts from morning 9.00 AM to 9.15 AM during the market days. This 15 minutes consists of mainly 3 slots.

1) 9.00 AM to 9.08 AM-Order collection period-During this period you can place the orders, modify or cancel them.

2) 9.08 AM to 9.12 AM-Order matching period and trade confirmation period-During this period placed orders are confirmed based on the price identification method called “Equilibrium price determination” or “Call auction”. Will discuss about these methods below. During this period you are unable to modify or cancel the placed orders.

3) 9.12 AM to 9.15 AM-It is called buffer period and which facilitates transition from pre-open to normal market session.

How Equilibrium Price determination or Call-auction session actually works?

Let us say with example of XYZ stock and previous days closing price of the stock is Rs.100. Now during the market pre-open session types of price and quantity reflect may be as below.

1) Scenario I-We found only one share price with highest trading quantity.

NSE-1

In above case share price with 105 have highest trading quantity with 27,500. Hence it will get executed as equilibrium price or call-auction price.

2) Scenario-II-We found two matching maximum tradable quantity for different share prices.

NSE-2

In above case we found two matching maximum tradable quantity for share price of 105 and 99. In that case minimum unmatched orders quantity is for 105 (8800) than 99 (9000). Hence in this scenario share price 105 is considered as equilibrium price or co-auction price.

3) Scenario-III-We found two matching maximum tradable quantity and same unmatched orders for them too.

NSE-3

From above table we found that for the share price of 105 and 99 we have matching maximum tradable quantity and same unmatched orders. In such scenario previous days close is come into picture.  Here I told earlier that previous days close for XYZ is 100 which is nearer to 99 than the 105. Hence in above case 99 is considered as equilibrium price or call auction price.

4) Scenario IV-We found two matching maximum tradable orders with same unmatched orders and share price are equally distanced from previous closing price of share XYZ.

NSE-4

In above case we found that share price 101 and 99 have same maximum tradable quantity and same unmatched orders. Also share prices 101 and 99 are equally distanced from previous days close. In such case previous days close share price 100 is considered as equilibrium price or call-auction price.

Points to remember regarding Pre-open session.

1) After finding the equilibrium price or call-auction price all market orders are executed at the equilibrium price and all no executed limit orders are carry forwarded to open market as it is.

2)  Price band of 20% shall be applicable on the securities during pre-open session.

Any comments or suggestions?????

  1. Sir,
    Nice article.

    Could you please explain below point.

    2) Price band of 20% shall be applicable on the securities during pre-open session.

    Another Query: After Market Order with Market Price (not AMO with LIMIT), How it is calculated in pre order session.
    Which has highest priority?

    Reply
    • Dear Smruti,
      It means the bid and offer price must not be more/less than 20% of the previous day’s closing price. “Which has highest priority?”-The price discovery will continue as usual irrespective of the price you set the order.

Hello sir I would like to know where can I get this premarket data does anyone provides this because I need the quantity of shares traded in the premarket session which is responsible for a gap up or gap down.By knowing that one can predict if it’s a real or just an anxiety move since some stocks might be oversold or overbought because of certain news but the performance of stock might not reflect the move and there may be a chance of gap filling. It would be really helpful if you could tell me where I can get this since I trade on zerodha they don’t provide this. Even Amibroker with its feeder doesn’t provide that or if there is any setting which I could change on amibroker such that I get the volume on the premarket data please do tell me thank you.

  53. Nice article. Let me ask a question. Some sites advocate the application of the Chandelier exit by setting your stop upon entry at a multiple of, generally, 3 times the Average True Range (ATR). The ATR at entry for this trade is sitting at 0.0122. So they have calculated ATR as 3X122 pips=366 pips and have the initial stop at 366 pips lower. Now let me know how to calculate for the Indian stock market? What should be the equivalent of pips in the Indian stock market? I hope you would kindly help me.

  56. Hi!! Thanks for the information. I am very new to the technical terms in the market. So, my question may be naive. My question is I want to buy a stock xzy. The closing price yesterday was 100. Just imagine the lower and upper circuit for the stock is 20%. I strongly believe the stock will move to 115-120 range after few minutes market opens. Now, i want to buy the stock at better price anywhere between 100-110. If I want to place order during pre market session (i.e between 9-9.08 am), how I can choose the price? any random price between 100 and 110 or the better price (for example 105) will be shown any where in the broker site (in my case ICICIdirect)?

    Thanks

  57. So, the Equilibrium Price could be higher/lower than the pre-open price(which we get at 9:08 am) of a stock. Please correct me if i am wrong …

  58. Sir thank you for the great article!

    Can I place after market order at market price so that it can get executed at equilibrium price. For example, Infosis results are out and it was excellent, last closing price was around 1162, I anticipate it to increase on Monday. To avoid gap when placing limit price, can I place a AMO at market price and by placing market order will I get best price around the equilibrium price.

  63. IS there any way to carry forward my last day selling order to next day in NSE?

    Also what strategy should i adopt to exit from a stock which is going in lower circuit from past 4 days?(Every days some 3000 sell oders is bring the stock to LC)

    I want to place a request in a such a way that it get executed first in NSE as NSE will place first come/first serve basis

    At what time/what method should i adopt so that NSE will take my orders first?

    Reply
    • Sam-No, you can’t carry forward your selling order. The order expires after the market closure. It is hard to guide as to what you have to do with the stock which is trading at lower circuit. It is purely your call of buying. Hence, can’t guide the strategy to SELL from my end. It is everyone’s dream that their orders MUST execute at any cost. But it will not happen like that. Because it is market driven by many of like you and me.

    I understood the process Pre Open Session as you have explained. However, one question that I have is whenever I place an order to buy or sell any stock at market price instead of limit order during Order Collection Period then I suppose my order will be considered in or as equilibrium price. Is that correct?

As far as institutes, I did my CFP under my mentor Mrs.Padmalochini who not associated with any institutes, but handles the classes individually. Institutes only care for you up to the time of your fee payment. Later on they not bother whether you completed or not. Hence, I suggest to follow her.

I placed an order at 9.01 or earlier but in pre open session Stock price is going down and i could notice it at 9.05 (still 3 minutes to end pre open session) so can i cancle it before 9.08(say at 9.06 or 9.07) or it would have been excecuted already

    Why there is difference in Previous close and open price ?

    • Amit-When trade start today and there are huge buyers then automatically the first trade get executed at higher price (in your case it is Rs.427). So it shows the difference. At the same time, when there is a huge sellers then the price will automatically goes down (like 310) also.

    I have placed the Buy order of 500 shares at 59.75 . the market was about to close . so my order was partially executed and executed quantity was 100 . But the strange thing is the share closed at 59.65 . I mean how can it be possible ? Will my remaining quantity go to pre market session next day ? Kindly clarify .

    • Vishal-Punching at server of NSE or BSE makes this difference in execution. No, it will not carry forward the order. It is considered as lapsed order.

      • Thanks a lot for replying . But still its difficult to understand that my order is already partially executed at 59.75 which means my order should be considered first as a buy at this price on the first come first serve basis .

        So , now the question is if my order was already there at 59.75 , how can the stock reached the 59.65 level without fully executing the partially executed order at 59.75 .
        This is total strange and my money is blocked for 500 shares instead of 100 shares. I am not understanding it .

  78. Hi,
    I checked Pre-Open Order Collection for NSE at http://www.nseindia.com/live_market/dynaContent/live_watch/pre_open_market/pre_open_market.htm. When I click on any scrip it tells me me buy QTY, Price and Sell QTY. and finally it shows Pre-Order Collection summary. I am unable to follow your instructions above in those examples and IEP is something different. Can you please explain how the aggregation works in buy and sell qty? I think that is one of the parameters for deciding the price.

  85. Great writeup. What a way to shaft innocent derivatives holders. The pre-open session has been the biggest fraud heaped on unsuspecting traders of NSE/BSE. I don’t understand why dalal st. crooks are allowed to benefit from gap openings and retailers/small investors always lose. SEBI is very much a party to this institutional fraud. We have the same round robin trades throughout the day. Indian markets are no longer Indian.
