Can I also ask you another basic question around the following stat found on the earnings chart page: what is the difference in the two sets of numbers eg -0.2308 and -2.83%? This is for INTU, with average RV at T-15 = 7.5% and T-0 = 4.05%

I can see -0.2308 = (4.05- 7.5) / 15

But if I do (4.05/7.5 -1) / 15 = - 3.06%   ..........which doesn't tie up with -2.83%. Is my interpretation of the calculation completely incorrect?

I nned to confirm that with looking at the actual calculation. But as a quick shot, I think the difference in the percentage value is because I used continuously compounded returns for the decay (because losing 3.06% each day anew would result in higher losses than implied by the pure arithmetic mean. This is because you calculate each day from a smaller base.)

@mimi It is hard to do a analysis from far. Have you followed the instructions on the download page? I heard that was an issue for some members, though I have not encountered that error myself.

Thank you for the program Christof.

Unfortunately I still receive the same compiling error like mimi.

I am using Win10 and Excel 2010. Is my Excel version maybe too old?

I am using Excel 2019.

@mimi, @GID1, I do not think that the excel version is too outdated. I am honestly a bit flabbergasted reading the message, because the main methods the tool calls in the IB API have not changed in practically decades. The calls supply the correct parameters. I have not seen it on my machine yet. Do you use the correct 64/32 bit version?

@GID1 I just wrote you a PM with an access code.

##### Share on other sites

@Christof+ I don't know if it pertains since your tool uses the standalone API if I remember correctly but I had to change IB TWS to the Beta version for some reason recently, about 2 months later  the gf58ometer quit working.  I ultimately figured out that if I switched back to the Stable version all was well.  So between Beta and Stable, there is some difference in the IB TWS API, possible whatever change was made there was made to the standalone API as well.  IB support was not helpful, they blamed on something else that didn't even sound plausible, figuring it out was just plain luck.

Hi @Christof+ I hope you're doing well this week.  I was hoping to try out your Chartaffair service, is it possible for me to get temporary access to the service?

@OptionsIndeed, I just dropped you a PM with a code.

@Christof+ WORK and KODK show "symbol not active"

This happens now and then for those few symbols I look at (only the SO stuff). Is this something you could prevent somehow? I really appreciate how fast you react and that I can contact you personally, but workflow-wise its not so great ...

##### Share on other sites

@mimi currently symbols are added half automatic half manual. While  I cannot guarantee you will always find all symbols I do try my best.
I am conscious that this may not be satisfying, adding a symbol is normally a quick small job after a heads-up via PM or email.
WORK and KODK are live (WORK needs one more update run for the current cycle)

@Christof+ thanks for explaining the process and the quick update 🙂

I noticed the RV charts do not have any updated data after 8/27.

This seems to be the case for any symbol I pull up. Screenshot attached.

Thank you

Looks OK on my system. Check the "Start Date" to see if you've inadvertently limited it....

Thanks for the heads-up guys! Indeed, looks like there was a problem with the data upload today. Will fix it still today. Sorry about that!

It's just the last few days that appear to be missing. Do you have data for the highlighted green days?

Aah. Sorry - I misunderstood your question. Yes, you're right. The last couple of days are, indeed missing across the board.

All should be back to normal in about 1h. Sorry once again.

Hi @ilhomsher,

Yes, long leg expires always after the short leg.

HI Christof,

earnings charts seems to be off. I tried AMZN TSLA and it seems credit required for these stocks are only around \$1 a week, which is off a lot.

Hi @Christof+, could you look into the RV graphs for both the straddle and calendars for TCOM? It looks like 8 cycles are missing from the RV graphs, even though the matrix results for the last 8 cycles show data.  The last date shown for the RV graphs is Sep09/2019.  Thanks.

@ilhomsher, @poseidolginko  thanks guys, will look into this still today when I get to my computer.

##### Share on other sites

@poseidolginko TCOM is fixed. Thanks for the hint.

I still need to do further investigations, however, to understand why those cycles went missing.
Concerning calendar graphs, please be aware that you will see all the cycles only when choosing 'monthly' for legs apart. This is because not all weekly options have been available in all cycles.

@ilhomsher I agree these prices are too low. For now I am not able to deploy a quick fix. I need to dig a little deeper into the calculation.

Hi Christof. It seems that earnings short strangle data is still corrupt. Can you please check the methodology for large cap and price tsla, amzn etc. Thank you.

##### Share on other sites

@ilhomsher Thanks for the headsup. I immediately followed up the matter with a few symbols and calculation was correct. I have to admit it slipped through my fingers after that due to workload. I will tackle that and come back to you. I just ask you to give me some more time as Christmas is here in a few days. Thanks

I just signed up for Chartaffair and am having a difficult time downloading the Excel file. It is rejecting the Chartaffair key and the error message is "cannot paste to a merged cell."

How can I solve this issue?

Thank you.

Here is a newbie question:

What is the "T-0" day exactly?

Are there any differences between EA BO and EA AC?

##### Share on other sites

@cimat T-0 is the last trading day before the earnings announcement. "EA BO" means the earnings announcement is before the opening on that day, hence last trading day pre-earnings was the trading day before. "EA AC" means earnings are announced that day after the close.

T-0 is the last day before earnings, the day at which you have to close positions by the end of the day to avoid holding through earnings.   For earnings reports after market close, T-0 is the same day.   For earnings reports before the market opens, T-0 is the day before.

@Suresh D Gehi can you send me more details about the issue via private message? For which cells the error is thrown?

I had been confused with that difference.
