See the attached image where the IWM-NQTV 8:46am PT bar shows a low of 278.80. Using the Sierra High/Low for Time Period study shows the subgraph at what looks like 278.805 (not a .01 tick size level). The wick of the candle is not at 278.80, the low price. You can see the following candle with 278.80 drawn shows where that tick is at, and the crosshair is on 278.81. Unsure if this is a double rounding issue or not. Calling this out in case there is some subtle issue happening, and this is a good repro for it.

PT, Pacific and should be hard-coded in the attached .cht. So the 8:46 am candle is 2 hours 16 minutes after the RTH open today 9/28/2026. ^^added more verbose information above for historical reference of this item should someone look at it later.

First it does not make sense that there is any real problem and we have looked at this symbol, and the Tick Size for it is .005. So we do not see any problem here. You will see the .005 values if you set the Price Display Format to .001 for the chart: Chart Settings: Price Display Format (Chart >> Chart Settings >> Symbol >> Symbol Settings menu) Sierra Chart Support - Engineering Level Your definitive source for support.

I never set any custom tick size, and this is what I see when I do "Update From Server". I don't see at 0.005 there. I was going off the information from within Sierra chart using the settings set from the server/data feed. Thanks for taking a look and your replies.

The default symbol settings that Sierra Chart provides are not going to use a lower size than .01 for US equities. That is the standard, and we would not know if a particular symbol has a lower Tick Size. We are checking to see, if the NASDAQ Totalview Data Feed provides us the Tick Size for every symbol. It should but we are not sure about this. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

We do not see any obvious way with NASDAQ Totalview symbols to determine the Tick Size from the data provided by the Data Feed from NASDAQ.
