Price Velocity

[luxor]

Hi, I'm trying to automate something like Ameritrade's Market Motion detector but am having trouble with the formulas for price velocity, price acceleartion, volume velocity and volume acceleration. Does any one know what formulas would work well for this.

Hi Luxor,

Please excuse the tangental response, but are you still using TD AMERITRADE for some of your brokerage needs?
If so, we have a trading interface to TD AMERITRADE that's in pre-release, and just several weeks from launch.

If you're an eSignal client, the interface is integrated into all windows, such as Quote, Option Chain, Market Depth, and Advanced Charts (via the Attached Order Ticket).
* Interface installer

If not, QuoteTrader, our free trading application also interfaces with TD AMERITRADE.
* Setup instructions & files for QuoteTrader

We'd very much appreciate any feedback on its existing functionality, as well as suggestions on how it could be improved.

Thanks,

Brent

price velocity == current price minus previous price.

price acceleration == current price velocity minus previous price velocity.

volume velocity == current volume minus previous volume.

volume acceleration == current volume velocity minus previous volume velocity.
