Compare RelativeVolumeStDev Bars

[XeoNoX]

You stated "RelativeVolumeStDev ( StdLevel not vol)."
You stated "curbar.StdLevel "

For the most part without the source code you are working with we have no clue what those syntax u mentioned above means or what you are referring to.

And 2nd of all ...the STDLEVEL syntax on the RelativeVolumeStDev is a constant that is manually inputed and does not change, so it cant be higher or lower than what you set it at input. therefore it nullifies your scan.

Thanks Xeo, as I said I’m a dummy when it comes to this. What I’m trying to achieve is something like the following (not in thinkscript, just how the operations would work):

def curvol = standardeviation of current bar
Def uppvol = highest standard deviation over last 10 bars

if curvol >= uppvol then return false, otherwise return true.

I’m only interested in which deviation range the volume falls and not necessarily the actual volume. I.e. 1, 2, 3, 4, etc.

Does this help?

AddLabel(yes,
         "No. of closes above " + numDev + " RelVol Std Dev in the past " + count_length + " bars = " + count_above,
         Color.ORANGE);

above code counts number of bars within xyz relative volume standard deviation

Gorgeous! Thank you so much!

i kind of love this and would also love to see it as a custom watchlist column, with numbers indicating how far back in the past the last instance of xyz rel vol stan dev took place. possible?

i've been working on it myself, not with this study but with the tape momentum one, with not a lot of luck. i'm figuring if someone can do it for this indicator, i'll be able to figure it out for the other. likely story, i know, but ya never know!

well, i think i did it myself. didn't seem so hard ... ifn i did it right. anyone care to double check?

input count_length = 10;
def count_above = Sum(RelVol > numdev, count_length);

plot value = count_above;

just try and it out and see if it works, you can always have it plot below the chart and see how it works.

 

[floydddd]

seems to be working so far. thanks for the response. btw / if you've got a moment, how would you change it to show the number of bars back the last firing of the desired state took place?
