I tried looking for similar posts but I didn't see anything on this specifically. When using IB as a data source in Sierra chart, all of the data matches exactly to IB's TWS platform - which is expected. However it seems the way Sierra Chart graphs its moving average on available data is different from how IB TWS's platform does it. Sierra chart's moving average has the right data values, but the plot is little strange - if you eyeball, it looks as though the value is several times the volume - but the data window shows that it is indeed correct. That would suggest an issue with plotting. First screenshot shows the 50 EMA on Volume for Sierra chart, the ema plot is way off on IB, the 50 ema for Volume is where it should be, below the volume bar. |

The problem is the Scale Range for the Moving Average study is not set correctly or it is not set correctly for the Volume study. Check the Scale Settings for each: Chart Scale and Scale Adjusting: Opening the Scale Settings Window For a Study The Moving Average study needs to be set to Automatic. The Volume study needs to be set to the default of Automatic Zero Based. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
