I have a daily chart with a 40 SMA and 200 SMA.  Viewing the max range of the chart is almost two years.  Both SMAs fall short of reaching the left side of the chart by about 40 and 200.  Have I set something up wrong?  Thank you.

No, you have not done anything wrong. There is only 500-bars of data in any given time frame. All of the indicators use those 500-bars of data. There is no hidden data beyond the left-edge of the data which can be used to calculate the indicators. There just isn't any more data.

Since a 40-Period Moving Average requires 40-bars of data for its calculation, the first bar for which it can be displayed is the 40th bar of data. This means there will be at least 39-bars of data where the 40-Period Simple Moving Average cannot be calculated near the beginning of the available data.
