Did you checked on the "G/L to include previously realized G/L's" ?

Thanx for shaing. Optionworkshop looks interesting. How much is the s/w subscription? I don't have IB. They seem to suggest CQG in their documentation. Is there extra fees for data?

You mean European residence can't open a TOS or TDA account ?

Here's the screen shot

Jay, File - Export. Then click on Line Format button to choose whichever field you wish to download. This is an excellent OV feature.

Agree Ron... It's a team work. You can explain the concept much better than I can. [/URL] You were spot on in explaining that shifting the long strike down is a better adjustment if market rallies and the IV skew steepens. I would like to share my thought about the choice between shifting the...

Well done Ron ! The discussions about adjustments to M3 are spot on. Thanx for the video.

Yes 20-30 pts is good enough to see some effect. In terms of software, no special software, just the "good old excel" with TOS DDE. As part of my firedrill, I also export matrix data from OV in back trader mode. With that i get 30 min interval data of options pricing, greeks and IV skew.

Let me use this as an example - look at the IV curves below. The red circle on the curves denote ATM strikes. Market moved from orange line to blue line - ie market moved up. IV dropped. Notice that as IV dropped, higher strike IVs drop more than the lower strike IVs. Thus making the IV skew...

Thanx Jay. I didn't even noticed that. I'll definitely go play around with the new feature. :)

Why not put in the specific request as a separate thread. Then add in poll for people to vote. If we get enough votes, maybe, we can get OV's attention.

Tested 7.83. It's very close to 7.64. This is based on back trader. Haven't had chance to compare live yet. But if it's like 7.82, then I think it is good enough in my opinion. The data below is from my Jan 2015 trade. Bear in mind, the greeks are based on 200 butterflies. The difference in...

Note from Len ..... I have found the problem. When first entering BackTrader mode, the program does not compute the MIV’s of the nearby options that are “brought back into existence” by going back in time. This was a new line of code that I added to prevent unnecessary MIV recalculations, and I...

I tested the new release. Seems wrong. Very different from the beta i tested. Already written to OV. Can you guys test and see if it's really a problem or the issue is on my end? I suggest you save a copy of your current OV folder as backup before you upgrade.

In my opinion the key here is "good enough to get us back to business as usual". In the past several weeks we have spent more time discussing OV's problems than on discussing trading. I don't think there is a "Holy Grail" of IV modeling, what we need a stable and resilient model which can...

I spoke to Len about three related but slightly different issues : (a) the new projected iv curve despite being tighter fitting to MIV, actually caused the unintended consequence of poorer modelling accuracy, (b) the greeks of 7.81 seems to be jumping around constantly in live trades, (c) the...

Bruno, I might be missing something but I can't think of why the modelling less affect OTM options. In fact what I know is the impact is greater at the two ends of the strike range, either deep OTM or ITM depending on Put or Call. In addition, as we are dealing with bearish butterfly, an Iron...

I have tested the v7.82 beta that OV released to me two days ago. V7.82 is supposedly the version that brings back the old volatility model. Preliminary test is quite positive. The greeks and T+0 line are very close to v.7.64. Looks like they might have found a way to revert back to the "good...

Hi Bruno, Why's Iron Fly a solution to the issue ? Not sure I understand.

Ron, You are absolutely right. Depending on whether the skew is flat or steep, it'll sometimes be more advantageous to roll up (or down) the shorts and some other times to roll up (or down) the longs, although they provide the same amount of delta. Sometimes, looking at the skew curve, it can...
