HI,
Would you be able to write a fx for OBV xUP 10 sma? Not able to use TSV (unless a generic fx).

Thanks

Try this:

OBV1>=OBV10 AND OBV1.1<OBV10.1

Not sure what you mean by "generic OBV fx". Craig provided the formula for OBV crossing up through its 10 bar simple moving average which is what you asked for initially. Please explain further.

By generic: the fx for OBV (not OBV in TCNET language)- and finally: crossing up it's 10sma.
Thanks

If I am reading your response correctly you are looking for the definition of OBV. That is what our Knowledge Base is for. Click the link for it at the top of the page and search for OBV. You should find the definition there.

I gave your PCF for the crossing above.

The formula is

$OBV = OBV_{prev} + \left\{ \begin{matrix} volume & \mathrm{if}\ close > close_{prev} \\ 0 & \mathrm{if}\ close = close_{prev} \\ -volume & \mathrm{if}\ close < close_{prev} \end{matrix} \right.$

per wikipedia

You've already posted the formula for OBV by Granville. I also directed you to the KB that explains it as well. I am at a loss for what you are looking for.

thecurve,

My guess is that you are asking for PCFs for conditions on OBV that are written without using the OBV notation. For example, a PCF for OBV today greater than it was two days ago can be written:

OBV1.0 > OBV1.2

or without using the OBV notation as:

SGN(C0-C1)*V0 + SGN(C1-C2)*V1 > 0

Am I correct?

Thanks,
Jim Murphy

Would you provide me the equation (as above) for OBV1.0xUP10SMA?
Thanks again,

thecurve,
Please try the following:

9 * SGN(C - C1) * V + 8 * SGN(C1 - C2) * V1 + 7 * SGN(C2 - C3) * V2 + 6 * SGN(C3 - C4) * V3 + 5 * SGN(C4 - C5) * V4 + 4 * SGN(C5 - C6) * V5 + 3 * SGN(C6 - C7) * V6 + 2 * SGN(C7 - C8) * V7 + SGN(C8 - C9) * V8 > 0 AND 9 * SGN(C1 - C2) * V1 + 8 * SGN(C2 - C3) * V2 + 7 * SGN(C3 - C4) * V3 + 6 * SGN(C4 - C5) * V4 + 5 * SGN(C5 - C6) * V5 + 4 * SGN(C6 - C7) * V6 + 3 * SGN(C7 - C8) * V7 + 2 * SGN(C8 - C9) * V8 + SGN(C9 - C10) * V9 <= 0

Bruce,

I glanced at another formula than the above (xavgs), now realize the formula you provided is Ok. When you said that you'll do your best, what xavg's were you seeing?!

Your the best, I mean it, and thanks.

thecurve,
I didn't see any XAVG() functions in the formula I posted. I thought you had an entirely different formula that you were going to post with nested XAVG() functions.
