2Yr Notes
Just an FYI that the 2Yr notes in CSI, symbol TU, appear to be incorrect for Friday. I'm showing 111.0 for high and settle which is way different than the CME is showing. TU2 is okay.
For you breakout traders might want to be aware of this potential issue and difference.

As you dig deeper and deeper to learn the truth, maybe your investigations will turn up data such as the random images posted below.
Good luck sorting out your problem!

CSI data, UNG (Nat Gas ETF) looks suspicious after 4-for-1 Reverse Stock Split on February 21st.
I held a short position for several weeks beginning January at $6 and change per share. I exited the position well before February 21st.
After last night's CSI price update my equity curve got seriously damaged for the several weeks I shorted UNG. I am using Broker Positions.
To the best of my knowledge I should not need to go into Broker Positions to make an adjustment since I was in and out of the position at the pre-split price.
Is there something that I do not understand, or is CSI at fault here?
Thanks everyone.

After not receiving any replies to my post I decided to take matters into my own hands.
I deleted my Broker Positions for UNG then called test.UpdateOtherExpenses() with the gain from that position on the date that it was closed.
I know that my action skews my stats (among other things UNG is no longer counted as a Win.) But it was more important to me for my equity curve to return back to normal.
By the way, I did experiment a bit, and I found that if I kept the broker positions but divided my shares by 4 and multiplied the entry and exit prices by 4 then my equity curve returned to normal. But I did not opt for this solution for two reasons: (1) if UNG reverse splits again in the future then I have to come back and fudge the numbers again, (2) I should not have to do this in the first place!
I wish I could say that I had the time to delve into this problem further but alas I do not.

Positions changed with the last download
With the last download, Equity curve has changed and with that, lot of positions do not match.
I can't find any wrong price.
I am alone?
Thank you
