My GC DOM is Crossed and prices are incorrect/missing/gapped as well as some incorrect quantities as far as I can compare to TT.

In some price levels the qty is actually illegible or layering multiple qty's.

Of note, last trade price is UPDATING CORRECTLY. See Screenshot.

Steps I've tried:

- Chart Setting >> Tick Size & Price Display are set to = 1 tick
- Chart Settings >> Market Depth >> Market Depth Combine Increment Ticks = 1
- Auto-Set From Data Feed Toggle Yes/Apply
- Chart Settings >> Data Limiting >> Days to load change to 10 from 1.

- Global Settings >> Symbol Settings >> Uncheck "Use Custom Symbol Setting Values" >> Update from server >> Apply/Ok.
- Chart >> Reload and Recalculate
- Open Trade DOM from Scratch: File >> Open Trading DOM >> Choose "GCQ26_FUT_CME" >> Open Trading DOM Button [Confirmed Q26 is highest volume/ front Month Contract]
- Edit >> Delete All Data and Download ---> Found out [message log] that feature is only good for intraday chart data


Please Advise.

Best,

Kurt

Set this to 0:

- Chart Settings >> Market Depth >> Market Depth Combine Increment Ticks = 1

Although it should not matter if it is 1.

Reconnect with File >> Reconnect.

We do not do not see any issue like this.:

Is this issue occurring in a sub instance of Sierra Chart? If so, you need to do this in the sub instance:

- Global Settings >> Symbol Settings >> Uncheck "Use Custom Symbol Setting Values" >> Update from server >> Apply/Ok.

And then reconnect.

Ok that fixed it.

But when Reconnecting the platform froze so I did an End Task and it come up after restart with the Depth Combine Increment set to = 1 but data was now ok.

Ultimately I want to use a larger tick size for GC given it's volatility.

I have tried to set it via File >> Symbol >> Symbol Setting >> Tick Size = 0.5.

When I do this the ladder and qty's look fine (since implementing your fix), BUT my "Recent bid/ask Volume" data disappears and remains blank even after new trades.

I have Chart Settings >> Market Depth >> Apply Combine Increment in Ticks to Other Market Data Columns >> Yes

Depth Combine Increment is still set to "1", it's just tick size I've changed to 0.5 per tick.

FYI I'm on Version 2901 64-Bit, Revision 56402

Are you able to see proper data if you add recent bid/ask AND set a 0.5 tick size?
