market condition

Jan 20, 2011
Hi, I am new to trading and need your suggestions on this.

I have got 233 tick bars chart on Tradestation and I want to plot lines on the chart that will give me an idea of how many bids and how many asks are coming in a given time period. I want to include the bid size and ask size in the equation so I get an actual market price based on the number of asks, number of bids, ask size and bid size for a given time period.

Is it possible to plot lines on the above criteria.

Any suggestion would be highly appreciated.
