Index not displayed correctly (large value problem?)

[Toast]

I'm looking at a calculated index (DI6A.Z in this case) from IQFeed which works fine in NT6 but in NT7 it does not display correctly at all. See attached screenshots (first one is NT6 displayed correctly, second is NT7).

I don't know if it's something I can adjust to make it display correctly or if there is a problem with NT7 (value overflow or something due to the large numbers?). In NT7 it looks like there are negative (?!) values which is obviously wrong.

This is from a fresh new install with clean new data loaded.

Hello Toast,

Thank you for your post.

I will need to test this on my end and will follow up with you as soon as I gather additional information.

Thank you for your patience.

Can you please tell me what mapping and Exchange you are currently using for this instrument.

Does the exchange make any difference? I just used whatever, since it's a S&P 500 thing I used CME as the exchange.

The symbol map is IQFeed "DI6A.Z" as I mentioned in my post.

I am going to forward this to our development team and will follow up with you as soon as possible.

Can you please change the current tick size with the steps I have provided below:

• Tools
• Instrument Manager
• Select DI6A within your Available master instrument list
• Edit
• Definitions tab
• Tick size: set to 0.25
• Click Ok
• Remove DI6A from your Default list and add it back in

Please let me know if the issue persists after this procedure.

Nope, doesn't fix it. I tried a couple different tick sizes too, none work.

I still see a lot of negative numbers displayed too.

For what it's worth, in NT6 I'm using a tick size of 0.01 and it works fine.

I will continue testing this on my end and will follow up as soon as I gather additional information.

Thank you for your patience.
