Hi, I've had a strange issue crop up. For some reason, when loading my chartbook with a continuous contract on FGBL, Sierra keeps truncating 2 of the intraday files (FGBLH3 and FGBLU2) effectively making them empty. I've attached the message log and 2 images of my sierra chart folder. What I've done is as follows: 1) Start SC and connect to open e-cry. 2) Find symbol - open intraday chart for FGBLU2 and FGBLH3. The data downloads (see screen shot 1) 3) Disconnect from open e-cry 4) Open a chartbook which includes a intraday chart ranging all FGBL contracts FGBLM2 - FGBLH4 5) For some reason SC then truncates specifically the FGBLU2 and FGBLH3 files to zero length, but loads everything else ok. (screen shot 2) 6) Resulting continuous chart then has missing 3 month gaps where data from these 2 contracts should go (screen shot 3) Why is this happening? I can get around this gap by making sure I reload the continuous chart whilst connected to open e-cry, but sierra will still truncate and re-download data for those 2 files every time. This is an issue as I am making a manual adjustment to the data files to make sure the back-adjustments agree to a continuous chart from IQFeed (it doesn't by default). As these 2 files are continually deleted and redownloaded the adjustments for these 2 files don't "stick". Message Log for the above 6 steps follows below.

This problem has already been resolved. Update Sierra Chart by selecting Help >> Download Current Version. This is an issue as I am making a manual adjustment to the data files to make sure the back-adjustments agree to a continuous chart from IQFeed (it doesn't by default) What manual adjustments are you making? In what way do the back adjustments not agree to IQ Feed?

I've updated to the current version. Will have a look. As for the difference to IQFeed: This could be just due to Open E-Cry. The symbol settings by default for rollover are: Number of Calendar Days before friday count within contract month Number of calendar days = 0 Friday count within contract month = 3 This makes no sense. Trading largely shifts onto the new contract on the last day / last 2 days. The last day to trade is a half day session that ends at 12:30CET. I'm rolling the chart over so that the morning of the last day to trade, I am on the new contract, as I'm not interested in the low volume half day session on the old contract. I only seem to be able to achieve this by using the following date rollover rule: Number of business days before specific calendar days before contract month Number of business days = 1 Specific calenday days before contract month = -8 (minus 8). This gives me the dates as per the log above, which I see as correct. Please advise if there is a better way to achieve this. However, the resulting chart then doesn't match IQFeed. (I deleted & downloaded all data for the series of contracts making up the continuous chart to make sure the problem wasn't some adjustment I did) As for the differences, I obtained a daily high from an IQFeed continuous chart for all the contracts making up my chart. Comparing these to the Sierra result, I get a result as per the attached comparison.png.

We obtain the rollover rules from the EUREX exchange website. Maybe we got it wrong. Trading largely shifts onto the new contract on the last day / last 2 days. Are you saying that trading goes to the last business day or two in the contract month? So the last rollover would have been December 30? Are using one of the back adjusting Continuous Futures Contract options? Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

I'm using the continuous futures contract option - date rule rollover, back adjusted Hmm, think we're talking around each other a bit here. I can only find the contract spec's on the Eurex website, nothing about rollover. Now, specifically, taken from http://www.eurexchange.com/exchange-en/products/int/fix/14770/ ("trading" section, not "latest") Delivery Day The tenth calendar day of the respective quarterly month, if this day is an exchange day; otherwise, the exchange day immediately succeeding that day. Last Trading Day Two exchange days prior to the Delivery Day of the relevant maturity month. Close of trading in the maturing futures on the Last Trading Day is at 12:30 CET. So for FGBLZ3 (Dec contract) the delivery day was 10 December 2013, and the last trading day was Friday 6 December 2013. The last trading day is however, only a half day session with little volume. Now per IQFeed, they roll over the same contract 1 day before expiration day (taken from: http://www.iqfeed.net/symbolguide/index.cfm?symbolguide=guide&displayaction=support§ion=guide&web=iqfeed&guide=commod&web=IQFeed&symbolguide=guide&displayaction=support§ion=guide&type=eurex ) Symbol there is BDH14 for FGBLH4 So effectively, the last day with data for FGBLZ3 / BDZ13 is Thursday 05 December 2013, and from 06 December 2014 they will show FGBLH4 / BDH14 I'm a bit confused about where December 30 came from?

OK not sure what we were looking at previously in the EUREX specifications. So we have to create a rule like: Number of Business Days Before Business Calendar Day in Contract Month. December 30 was based upon this in relation to a December 2013 contract: Trading largely shifts onto the new contract on the last day / last 2 days. It was not based upon the alternative Rollover Rules that you described. Since those were not completely clear because of the negative number. We were just commenting on that one particular statement to try to get a sense of the rollover date. Sierra Chart Support - Engineering Level Your definitive source for support.

Trading largely shifts onto the new contract on the last day / last 2 days. <-- Apologies, rereading that, that was very unclear from my side. One thing, given Delivery Day The tenth calendar day of the respective quarterly month, if this day is an exchange day; otherwise, the exchange day immediately succeeding that day. That "succeeding day" might complicate this slighty. Example was March 2013. 10th March 2013 = Sunday, so delivery day is Monday 11th 2013, rather than Friday 8th March 2013. And thus the last trading day is 7th March 2013. Using your existing rule Number of business days before specific calendar days before contract month Number of business days = 1 Specific calenday days before contract month = -8 (minus 8) Seems to get the correct rollover date (assuming you want to match IQ Feed) of 1 day before last trading day for the contracts I've used so far. However, this still left the resulting charts looking different to what IQFeed apparently has (as per that comparison.png)

We understand the rollover rule, and we can program it working according to the exchange rules. This is no problem. Once we get this working, we will look more closely at why there is a difference to IQ Feed. Must be something about the back adjustment calculations.
