You must have met people who say that the stock market is a force, do not invest money in the stock market, people get ruined here, no one can earn money, well those people are speaking the truth from their experience, they must have seen such people who do not earn money, get ruined, lose money, but let me tell you one thing, if you watch this video completely today, then first of all your perspective will change and in fact you will be able to change the perspective of those people also because according to me the stock market calculator is a business, now understand that I am not talking about stocks here, you go to the market and buy gold, now you buy gold, you buy gold, the rate of gold increases, you get profit, now if you take a good amount, say ₹ 1 crore, you go to buy gold because the price of your gold will increase, if it increases then there is profit and if its price decreases then there is loss, it is a simple thing, so will you call it gambling? Now tell me, we will call this gambling, we do not call it trading alone, we have traded it, whether it is gold, turmeric or rice, you talk about it, there is actually another community in shares also, but here the topic is of option chain lysis, why I am starting from here because people think that share marketing is gambling, here people are ahead, you know that in option trading 90% of the people lose their capital in the first 90 days, so 90% of the people lose 90% of their capital in the first 90 days, the reason for this we have discussed earlier, but today with logic, see we are understanding the option chain for you, today I will talk about refinery or option trading, actually I will talk about the stock market, how long is it risky, it is risky, until you do not know what is going to happen, you do not know what you are trading or you are trading on logic, today I will show you that we have to make a very well thought out strategy here. We should know what is our stop loss and actually we should also know whatever analysis we are going to do, once you understand that analysis, watch this video till the end. I am telling you really your view will change. So first of all we are going to analyze the option chain. So where will you find the option chain? You just go to Google and see, I open the option chain here in front of you. Actually, you can also search it. So this is an option chain. We are going to analyze it. You just go to Google and write option set. As soon as you open the NC chain, your option chain will open here, just like we opened. So here you can search. If you want to see the options of Nifty, depending on whether you trade in it or not, if you read 50 meters for example and here you can see the expiry time. If you select it, now we have selected the current which is our yesterday’s expiry. Today I am making this video, I am making the second one of Revenor. You can watch it later also. So this is our 3rd November expiry, i.e. tomorrow’s expiry. So now you see here, you see the option chain, what is the most important here? Here it is not important that this side of mine is the call side, this side of mine is the put side. Here is the LTP and these are the strikes, the premium of different strikes is coming here. This is not so important. This D is in the money. This D is out of the money. For example, here the white ones are considered out of D for you. The yellow ones are considered in the D money. What is important? Here you respond to the open interest and the change in open interest. So I will tell you the change and open interest and how you have to understand it. But here you see it means open interest. This is very important. It is important to understand the meaning of open interest. If you understand this and master it here, then it will be very easy for you. Now when you see here what does this open interest create? Open interest tells how many lots are standing right now. Interest is created here. Now you can understand this interest. Here you can write the number of lots. For example, if I talk about 18200 here, then you can see 18200. What is this quantity? This is the number of lots. What is the value of Nifty lot? So if you multiply it by 15, then you will get the number of shares. Now you must have known that if you want to sell one lot of Nifty, then you have kept a margin of about ₹ 1 lakh on the available lots. To sell ₹ 1 lakh, you have to multiply it. If I am talking about 18200 only, then 1 lakh 84000 lots are there. How much money will it cost to sell it? Tell us by commenting. Let us see here in the same way, we are 1800, so this is our Oat D Money. At this time D Manipal 67000 lots, you can see, you see ₹1 lakh to sell one lot and he tries to tell you something. Now what is that, I will tell you the most important thing in option change analysis that we have to learn.
