how about the account insurance? I think they have huge insurance like $25 million or something per account?

How does the NYSE manage to hold on to their specialist system?

I just found out strategies with the keyword "stop" slows down drammatically with multichart. With other strategies I was actually able to speed up optimization ~4x with a quad core machine using multichart when compared to TS that only uses a single core. I reported the problem to tssupport...

I'm a customer of multichart and tradestation. Despite the latest improvement on multichart, I still find tradestation to be 4 times faster (with 1 core) in optimiztion with my strategies than multichart (with 4 cores). I find this ridiculous as multichart is using 4 times as much...

Slippage is huge these days. I experience 20 points slippage on a daily basis :( Ticks jump all over the place

How about the possiblity of tipping off your hand at a poker table, possibly to other geniuses?

IB said they checked price at COMEX and "those price were effectively paid" and nothing is wrong with those trades and won't adjust. What does that suppose to mean? I see bid above ask right before my execution price why would this happen? Also I see there are many trades that went thru...

I think I should start doing that.

I got one @3.4815 and one @3.4970 Ouch...

Why would this happen though? Did market makers take their orders out from the book at light speed all at the same time or something else?

It's Comex Dec Copper... happened 8:21:16 today Yeah I use market orders only. It's a personal preference and I'm ok paying for liquidity. But this time it goes thru inside ask and if you look at time and sales it all says "above ask" One execution price I got 3.4815 isn't even showing...

I just had my order (Dec Copper) traded 170 ticks+ above the inside ask. Does anyone have such experience before? I've never encountered this problem before. Does anyone know what I can do? I'm trying to contact my broker (IB) now and see what they can do...

Whoever conceived subprime ("subcrime"?) CDO is a genius. They tie themselves together with the interest of homeowners and make a chunk out of the housing bull market for a decade without buying or selling a single home. When they lose money they can simply ask the government to bail them out...

You obviously don't have a clue about the Refco episode...

Yeah, I'm aware of the 30M insurance and I'm not losing my sleep. Still it's going to be a long wait for the claim if it ever happen.

I have my trading account with IB. Given the current market volatility and liquidity crunch I'm thinking whether there is any reason that I should be worried about the safety of my money. From my understanding: 1) IB is ruthless in dumping positions that doesn't meet margin requirement and...

Thanks Nitro. I've learned a lot from your posts. I will start to spend some serious time on the math down the road. Many thanks!

Hi Nitro, Let me try to summarizes what I've got from your reply - The "edge" of an option MM boils down to the following three things: 1) Better volatility estimation model 2) Better executions (ie. better managing legs and hedging risks) 3) Having a better vol fitter who's basically...
