I follow Barry Taylor (enmini-watch.com).  He uses TradeStation data/charts for intra day trading.

1. One indicator is “Better ProAm” and he displays "professionals” as blue tick bars (large volume/trade) and “amateurs” as yellow tick bars (small volume/trade).
2. Another indicator is “Better Momentum” based on “Volume at the bid price”, and “Volume at the ask price”’

Apparently this data is available in the TradeStation feed.  Please tell me if they are available in the Metastock feed (either intra-day or EOD) or if they could be added.  Thank you.  Bill Roberts

 

Hi,

MetaStock's Downloader is for End-of-Day only. Our DataLink (End-of-Day) data feed would not have anything like this, as it simply provides a single volume value for the day.

In our XENITH (Intraday) data feed, you can get tick volume and you can also create "Tick Bars" that will sum up the volume for each tick bar in a chart. However, you have to actually load the chart as tick bars in order to capture the volume data in this way. The MetaStock formula language does not have a parameter for the time interval, it simply calculates based on what is in the chart.

I do not know much about the system in question, but in theory you could write the formula based on a number of tick bars and divide the volume into the number of ticks to get an average trade volume per tick bar (i.e. if you're looking at a 50 Tick bar chart your formula would essentially be):

V/50

You could make it a bit more dynamic using the Input function so that you could adjust the formula more easily based on the Tick Bar number of your choosing. This formula would be limited to chart indicators, as we do not support using Tick Data in our Explorer (scanning) or System Test power tools.

In a Chart, you can also "Change Field" in MetaStock RT and view Bid/Ask data (including the volume) but there are limitations to this as well.

In the future we are looking to expand the MetaStock formula language to be able to utilize different data fields (i.e. not just Open/High/Low/Close/Volume/Open Interest) but I will make sure to pass along your feedback!
