Hi all,

I've been doing some research on reading the tape and order flow analysis, and I've become very interested in incorporating those ideas into my trading. I was watching a video which included a DOM using the Jigsaw program (a similar-looking DOM is pictured below)



I noticed that this appears to contain the information one may be able to glean from Tradestation's Matrix and Time and Sales windows, but consolidated into one application.

I have a couple questions regarding this.

Is it possible to programmatically extend a Tradestation application, to, for example, incorporate those bid trade and ask trade columns that appear in the above DOM into the Matrix, or to aggregate the prints that show up in the Time and Sales by time and bid/ask condition (to get a better idea of block orders)? Is it possible to extend any of the applications in this fashion? If not, how about making a custom application using piped data used by those applications? Or, would using something else altogether make the most sense?

Essentially, I'd like to be able to use the order flow to gauge market sentiment using elements similar to the ones presented in the above DOM + Time and Sales. While the Matrix application alone already has most of what I'm looking for, it's missing those bid/ask trade columns (which could potentially be observed from Time and Sales), which I believe could be particularly useful...
