Hi, I think there is a problem with the back adjustment of the september contract of the Osaka mini nikkei. While today (june 8) the new contract (september) went down 40 points compared to the last contract (june), the historical chart went up 30 points compared to the last contract (june). I think the historical chart should have gone down 40 points as well. Right? |

I changed the open price manually editing the daily files and it worked well! But every time I log in Sierra it redownloads the historical data and overwrite what I edited! |

Yes this is true and is documented in the documentation linked to: If you are modifying the open prices for the last two dates in a Historical Daily data file, this will be a problem because those will be rewritten at least once a day. You will have to periodically update those open prices until they are no longer the most recent two days in the Historical Daily data file.

Hi, Yes I was aware of it. The problem is that not only the edition of the last 2 days was reweitten, but all historical contracts I edited (since june 2016) were rewritten when I logged in. |

OK we have to think of a different way to do the continuous futures contract back adjustment modifications.
