Historical SC/IB Backfill Question

Interactive Brokers has historical bid, ask and midpoint data available. How do I get SC to have my historical backfill be based on the bid, ask or midpoint from IB? I've tried using the SC symbol suffixes, but only the real time data seems to be affected. The historical prices remain the same. Thanks.

In this particular case you need to disable the use of the Sierra Chart Historical Data Service: Interactive Brokers Trading Service: Using Sierra Chart Historical Data So you must disable it to be able to access the interactive brokers data and then re-download the data in the chart.

Does the SC Historical Data Service offer historical bid, ask or midpoint data? Or, is it only Last price data?

It is only midpoint data for the cash Forex and CFD data. This would be for symbols like EURUSD. In the case of futures it is always the last trade price data.

Do you know of any other data providers that works with SC other than IB that provides bid/ask/mid data?

The Sierra Chart historical data does record at each trade the bid and ask prices so you could use this study to see them: Bid & Ask Prices But not more often than each trade. And then you can calculate the average with this study: Study Subgraphs Average For more information, refer to: Using the Basic Arithmetic Studies Sierra Chart Support - Engineering Level Your definitive source for support.

I was trying to track the bid/ask or mid in between trades also so that I can dynamically track where the market is actually at, rather than the Last price that printed. Thanks for pointing out the Average study, that will be useful in the future.

I had an additional question about the Sierra Charts data. You mentioned that the SC Data records the bid/ask data only when a trade is made. However, I wanted to know if in between trades, if the -BID suffix is added to the end of a symbol, will the chart continue to track the Bid price in real time? I know it won't print the price as historical data until a trade is made. But in between trades, will I be able to see the current bid price move in real time? Thanks

You mentioned Forex and CFD data is based on the midpoint history. Do you offer CFD data on commodities? Maybe I could use that midpoint data for accurate spread trading charts. When spread trading, using the Last price won't work because if the trades occurred at different times, the bars will be highly inaccurate creating large spikes making it impossible for analysis. Hence, my neverending search for bid/ask/mid historical data that will always track the actual tradeable prices. Thanks again.
