A +/- 1.80 is a 3.60 range. From - 1.80 to + 1.80. But I may be confused about the english term to describe it. Sorry. Do you think the probabilities I gave are wrong, why? I gave them grosso modo, of course. I don't think they are wrong. I only want to know what is the logic behind their atm...

Thanks. I suspect you know that. Can you give me a clue.

Hi So, call 0.90 + put 0.90 = 1.80 The market is pricing in a range of +/- 1.80 , this is a 3.60 range. A 66 % probability, 1 sd, that the underlying will be between that two points at expiration with actual iv. All depends on the iv the market makers determine for that day. One day I will...

Hi please, is that correct ? What is the cost of delta hedging? interest, comissions, dividends. The cost of delta hedge changes along one hour? iv does.

Hi An options newbie question. Imagine this scenario Underlying at 266 and 1 Dte. The atm call is priced at 0.90 , What does it mean? Why the sellers are asking that price ? It seems that the sellers thinks the underlying will go as maximum to 266.90 until expiration. If the volatility remains...

Thank you for the responses. Sorry but I don't understand you. You say if I have -800 k cash in my account and I sell 800 k in boxes my cash will go to 0. Of course. But what happen if I have 300 k cash and I sell 800 k in boxes ? My cash will go to 1.1 milion and the margin for the boxes...

Please to simplify let's forget about the stock and the puts. So If you have 300,000 in your PM account, and sell 800,000 worth of boxes, your Equity with loan goes to 1.1 milions. You will have an excess liquidity of 1.1 and you can do whatever you want with that. It's that correct ? thanks

Hi Yes, I haven't found that difference anywhere. But it's a big difference and should be clearly specified. Yes , this is correct. A question about a Portfolio margin account. If selling boxes doesn't increase the ELV, as you are saying, also doesn't increase your Excess liquidity. If that...

Hi Obviously I did't catch what you was saying. Let me say it was not easy without a further explanation. Now with your screenshot it is clear. And I am surprised. And What you are saying here seems correct to me. And to buy a box seems logical that reduces your ELV since reduces your cash...

Hi The ELV is exactly the same in a portfolio margin account than in a reg t account. The difference is in the margin. Equity with Loan Value (ELV) – Forms the basis for determining whether a client has the necessary assets to either initiate or maintain security positions. Equals cash +...

Hi Is usual that I have a ELV like 20 times my NLV. They are different things. Net Liquidation Value - the total of all assets (position value and cash deposited with IB) marked to market. The amount of cash you would get by liquidating all positions, now. Equity with Loan Value - your...

Hi Yes, that has happened to me sometimes . But in a Reg T margin account. I thought that in a portfolio margin account might be different. And I thought that all Brokers had this kind of restriction. I remember I asked to @RobertMorse that question months ago. He told me that Wedbush has what...

Hi Thanks for that trick. It is good to know. But I don't understand one thing. The mark to market value of the box is not taked into account to calculate the Equity with Loan value. So I don't understand How this can drive to a margin deficiency. Margin deficiency is when Margin required >...

Hi A margin call occurs when the margin exceeds the Equity with Loan Value, but the ELV is not the same as the Net liquidation value. If you sell a box, the cash that you received goes to the ELV but the value of the options doesn't, if they are american . And that difference makes your...

Hi I have reviewed this thread as from another related thread started by @FSU https://www.elitetrader.com/et/threads/selling-spx-boxes-for-interest.319832/ Well I don't have a Portfolio margin account, but it seems that the margin for selling boxes is very low. If I sell a SPX 3,000 point...

Hi When in a thread participates people like @Martinghoul @Sig and especially @Maverick74 and @JackRab it is better to shut up and listen. I want to say something because the theory sometimes desviates us from the reallity. 1_ ITM american calls are only early exercicsed the day before the...

Hi That was a very interesting thread. I had never opened a short naked put. But it seems that if you can manage a naked put that goes against you, you will be able to manage any option strategy. So it is a good training. The OP had a short put at 1800 and the SPX went to 2580 that day . That...

Hi I have an IB account based in Euros but all my trades are in Usd. I have some doubts about currency risk when my puts are early assigned. When my shorts puts are early assigned, often, I am obligated to purchase stock. I usually don't have the cash to purchase the stock and the broker sends...

Spy continues trading after hours until 17:00 East time, but with little volume. Yes probably is what beerntrading and JackRab said. thanks

Hi out of curiosity. The Spy volume is very large in the very last minute of the trading session. That happens every day. Why? are they option market makers hedging their positions ? why in the very last minute ? thanks
