Sierra Chart and multiple trading accounts or data feeds
I hear you. Since I switched to Rithmic via Optimus, I am very close to dropping IQ, as I really dont need it for much, but it is hard to drop since it is such a good feed for historical data.
Yes, there is something included, but not sure where the SC hist data comes from, as I use the feed hist data.
I need the properly marked data for bid/ask cum delta. I have used IQ for that, but the Rithmic feed thru Optimus has data correctly marked, which I have been using all of this month. The main issue for me in the short term is to make sure that feed continues to work, and that the historical data for that feed works (it currently only goes back maybe 30 days).
Mike, a solution (a hack) is posted in that SC thread using price chart overlay. Essentially, the DOM depth has to come from the trading service, in your case TT. The chart data can come from a different feed such as IQ.
I am not sure, but I know the IB fill is based on 30 second data while the TT backfill is true tick data, so it may be broker dependent. TT fill only goes back 60 days though. Both are sufficient for my purposes, but if you are doing systems backtesting then you will probably need a separate data source to suite your needs. But yeah, this and the performance reporting they need to fix ASAP.
My thought was that it was provided by SC, because when I load a range chart in NT I get no historical backfill for either, but with SC I get historical backfill for both. Unless they have it programmed to pull 30 second data from IB when you pull up a range chart or something.
