Thanks, but this is just anecdotal, like you said. It is easy to fool oneself; the mental accounting tends to forget or omit infrequent but small "outliers" e.g. from performance chasing when the market moves away. The fact that you made money as a MM with customer market orders does not imply...

I think you are mixing up different users; but I am with IB, and my report about limit orders relates to my trading with IB.

Like I said I didn't have your experience after many thousands of limit orders. Perhaps they singled you out ;) I'm not sure which question in which initial post you mean; but I'm always interested in factual evidence of ways to minimize the all-in cost of order routing strategies, which is not...

I have used mostly limit orders for many years at IB for my relatively high trading activity, routing to individual exchanges, and in the overwhelming majority of cases I received the exchange rebates as expected. The rare exceptions were scenarios when the market moved quickly. I think your...

Based on my own experience with equities trading, I came to the conclusion that unless you have a "real" justification for a specific limit based on fundamental or technical analysis, on average the all-in cost of a trade (including slippage and unfilled orders with the market moving away) is...

Of course the real time quotes change when you submit an order, to reflect your order if it becomes the best bid or ask. I heard that options orders often get filled if your limit is at the midprice or one tick beyond the midprice. Have you tried that? It would assume that the midprice is the...

I may be wrong, but I think per regulation, brokers and market makers have to either fill internally, or post an order to an exchange within a short timeframe. (I forgot how the rules differ for marketable orders and non-marketable limit orders.) I doubt a broker as big as IB would violate this...

I see hoards of retail investors playing with options and succumbing to the fallacy that you can just roll out until you win (and/or "getting paid" to purchase a stock by assignment), making brokers and market makers rich, and not realizing they lose money in the long run. It's a fool's game. In...

The question is, is the volatility risk premium consistent, can superior risk-adjusted returns be had with selling volatility / options selling / options overwriting? The folks at QVR (google their articles) point out that the VRP has disappeared, turned negative since about 2013 due to the...

What kind of ICU visit would not be covered by the mandatory insurance?

Wouldn't it be unlikely that several legs of the combo simultaneously but separately get matched with an opposing order, on your side of the mid price? I always wondered what is the purpose of IB's non-guaranteed combo orders; is there a realistic chance to get better fills than in the...

I don't know, but I am doubtful that there is a quick and easy scheme, or generally that there is a strategy that can be learned in paid classes or with subscriptions or trading "clubs", that cannot be learned by reading free scientific papers and studies and by doing your own research. Not to...

SPX options have 0.10 minimum tick size (0.05 for certain spreads). ES FOPs have 0.25 minimum tick size.

I hope Interactive Brokers makes the box spread quotes visible to their customers. I'm not sure though if I understand why market makers were previously not allowed to quote box spreads and the other complex order types, and whether the new quotes will be just indicative or actually represent...

Would you mind shedding some light on your rationale? How does 45 days compare to 30 days or 90 days in terms of gamma risk (need to rebalance or hedge more or less frequently), assignment risk, theta exposure per risk, effective trading spreads and all-in trading cost per exposure? Any other...

The benefit of selling 2 options at 20 delta in comparison to e.g. selling one option at 40 delta would be less gamma? If so, noted; but how would the theta compare? Correct me if I'm wrong, but I think this would lead to taxable gains but non-tax-deductible losses (until the stock is sold) on...

Thank you! Looks like most products that offer to see the complex order books are not available to retail traders. How exactly would Silex data be visible for IB customers - in TWS, or via the IB API? What IB data subscription category exactly would it need?

I think you will sooner or later run into early assignment issues if you leverage or hedge with DITM calls or puts on equities, right? Not to mention the effective trading spreads might be higher than ATM.

What's the benefit of this "stock replacement" strategy over a much simpler synthetic stock position (buy ATM call, sell ATM put) ? The latter is much simpler in terms of cash requirement (if it is an issue), probably margin requirement, no gamma, etc.; so the synthetic stock position is simpler...

Are you saying that you can get complex order book quotes via IB RTD API? Last time I asked them I was told there is no way to get complex order book data. Can you please explain, would I query the quotes for the combination order; and what role does the "SecID" play? Thanks.
