SPX Option Volume Charting


New member
Hi All,

I noticed that SPX options data, particularly volume, cannot be charted on a standard SPX chart. I understand SPX is not traded, thus there is no volume, but it seems like TOS blocks any language related to volume on a SPX chart.

For example, I am pulling volume data from various strikes automatically and charting them as an indicator. All equites display the indicator except for any where the underlying does not trade shares (VIX, SPX, etc.). The indicator simply disappears, much like the regular TOS volume indicator (yet the indicator is still listed under the active studies).

Is there any workaround?

Hope that makes sense...
Thanks in advance.
