Does SierraChart have any indicators that store bid ask values historically? Secondly, is it possible to get the Difference Bar Indicator to display the difference based on the mid of the bid and ask prices for each instrument and have it update when those values change? Thanks so much.

Sierra Chart does store the current Bid and Ask price at every trade in the Intraday data for a symbol.

You can see these prices, with this study:
Bid & Ask Prices

And there are also the Arithmetic studies to accomplish what you want:

I followed the Instructions on Data Recording and appended -BID. My symbol is CLU25-NYMEX-BID. But it does not update when the Bid changes. Should it be? I am set to retain Tick data as per the instructions but not seeing the bid update on the chart.

We see absolutely no problems with that symbol:

It works exactly as it is intended to.

Can you confirm if it updates the Bid or Ask when the Last changes or when the Bid or Ask changes. I am looking for when the Bid or Ask changes.

The chart definitely updates when there is a change with the Bid price. It is not affected by the last trade price or Ask price.
