關於CQG Historical Data
Hi, 大家新年快樂，想請問有在使用CQG data feed的大大，關於CQG Historical Data的tick by tick data, 是30天還是5天?一直用SierraChart搭配CQG用得好好的，但前陣子tick by tick data只有出現5天和漏資料，後來爬了下文感覺是SierraChart為了推他們的Denali data feed才這樣搞，我看Best Data Feeds in Trading Software | MultiCharts 和 Sierra Chart announcement about Changes to Historical Data: IBKR, CQG, Rithmic, etc - AMP Forum (ampfutures.com) CQG Historical Data的tick by tick data都是30天。
我又看到Post From: HELPPPP WHAT IS WRONG WITH MY OIL CHART - Support Board - Sierra Chart，而我知道這邊有些許人用CQG但Platform不是SierraChart，所以想知道你們的CQG tick by tick Historical Data到底是30天還是5天?
畢竟CQG有支援亞洲的期交所像新加坡、香港、日本，
如果用其他Platform的CQG有30天tick by tick Historical Data，那就代表是SierraChart的問題惹...... 本帖最後由 nihao 於 21-4-27 08:13 編輯
以下來源:Is Sierra not requesting full duration of CQG provided tick data even when available? - Support Board - Sierra Chart
內文:
Summary: CQG provides 30 day of tick data on current contracts, but Sierra is requesting and downloading only 5 days
Sierra has given us fair notice in https://www.sierrachart.com/SupportBoard.php?ThreadID=58506 and via many other means that if not paying for and using a Sierra data feed "When using CQG data, there will be 5 days of tick by tick data and 1 Minute data for the prior time period and for current contracts only".
a) It is fair that Sierra doesn't provide data that isn't there in CQG for no payment
b) It is questionable why Sierra would refuse to download CQG even when available from CQG. The sole reason I am guessing is to push users to Sierra's own product. The difference between 5 day and 30 day can mean the difference of not usable vs. usable for many users (it is for me)
Now some details:
I am AMP customer, using CQG feed. I took the information provided by Sierra on face value, and dutifully signed up for a Sierra a/c that I am paying for (I don't like it but respect Sierra's decision to not provide discounted access through AMP), and Denali feed, and exchange fees that I have to pay for again (I will still keep my CQG/AMP feed and exchange subscription in case I need to bypass Sierra and log into CQG web to close positions in an emergency or just to have mobile access).
I keep seeing everywhere that CQG provides 30 day of tick data, contrary to Sierra information of 5 day. So I used a well known competing charting platform that has no historical data, connected to CQG and requested 50 day of tick data on EPM21. As advertised, 30 day worth of tick data appeared in chart.
At this point I thought well, Sierra documentation is incorrect. Testing time: I made a backup of my data folder, disabled sierra feed in settings, and requested 50 day of tick data on EPM21. And there was bars on chart! But soon it was clear it was a mix of tick and minute data. True tick data for the last 5 days, and all data before 5 days is minute resolution, with Sierra providing no warning of it being so. This confusing. Why would CQG provide tick data for 30 day to Platform X but not to Sierra? Time for a closer look in the message logs?

So Sierra would request and download 5 day worth of tick data (weekend and exchange holiday included, so it can be really less than 5 days <- 100% unusable data), but 30 day is available.
Why would you guys do that?
看來真的是Sierra Chart的問題，為了推廣自己的Denali data feed而抹黑CQG......
