I would like to add " Last VOl" & "Pre Market" Vol label to below code. I am not sure who the owner and should be credit.

Good Afternoon,
I was seeing if anybody could convert this to ThinkorSwim
Volume Trend Meter - Trading View
https://www.tradingview.com/script/ywEEvEtI-Volume-Trend-Meter/

Is this possible to be converted to thinkorswim?

You're awesome! Thanks @samer800!
 
What's the proper way to interpret the Dev Increase and Dev Decrease, what does this mean, and what action would someone take when these bars occur?

Please provide the script that you are referring to.
A quick perusal of the 9 pages of this thread, did not locate the use of the variables that you are referencing.
Perhaps you are looking at a different thread?

Hello All,

Can anyone please help me with a script that shows the up/down volume ratio as histogram bars? I would like to use it on any aggregation period.

Thank you

Chris's Enhanced Volume For ThinkOrSwim
Buy / Sell Volume Pressure Percentages
View attachment 913
Buyers and Sellers is not information available in the data feeds.
When we look at the movement of price in comparison to volume, it is called Volume Pressure.
The scripts discussed here are representative of the PRICE spread compared to the overall volume spread.

We create a percentage for buying and selling pressure by using the candlestick patterns weighted volume.
Volume Pressure identifies the price movement which when aggregated with volume it is used to define MOMENTUM not actual buyers and sellers.
You can't apply the momentum percentage to the volume number and declare that to be the number of buyers and sellers.

You didn't provide enough information to say where you went astray.
By default, ToS puts volume charts on the volume subgraph line.
But if you have "show volume subgraph line" unclicked in settings, no volume chart will show.

So, first make sure that you have dragged this volume study to a lower chart subgraph

If that does not resolve the issue, here is a chart with the indicator already applied:

Looking to see if someone can help me out here and maybe in a very creative way, show some sort of lower study visual on the buy vs sell histogram, or percentage line, or something unique to show the buy or sell volume percentage.

I'd love to see the percentage as the day progresses compared to each candle of price action.

And just for visual purposes, see the Buying Volume Pressure... it's been above 80%, and climbing to 90%+ since 10 am but no way to see this or can you tell by the regular volume buy/sell lower study.

Have tried it myself and have failed, miserably. :-|

Thanks in advance.

OK so I found something that could work...

I modified this study --> https://usethinkscript.com/threads/premarket-volume-pressure-indicator.14031/post-116641

To 9:30 - 16:15 to show buy and sell, and this is what I get (now I'm not sure if the calculations are the same or not) See lower study.

Capture.PNG


I'd love to be able to do some sort of a line to show percentage of buy vs cell in a lower line chart, but I can't figure out how to add it to my study. Where the buy line vs sell line will always equal 100%. In this case you can see that the calculations are different and they don't add up to 100% (looking at the far right of the chart).

I modified this study for lower lines --> https://usethinkscript.com/threads/premarket-volume-pressure-indicator.14031/post-116641

The histogram doesn't reflect what I'm looking for.
Yesterday for example, the buy % was basically at 70% and climbing all day... matching the days price action.

Instead of a histogram, is it possible to plot lines - green for buy % and red for sell %?
Basically always adding up to 100%?

This way the green line will show continues increase in buy % as the day progresses and the sell % will show continues decrease.

I hope this makes sense.
 
OK so I added the last 2 lines to the code to plot the buy and sell volume precentages;

def buyvol1 = Round(((h1 - o1 + (c1 - l1)) / 2 / (h1 - l1)) * v1, 0);
def sellvol1 = Round(((l1 - o1) + (c1 - h1)) / 2 / (h1 - l1) * v1, 0);
def buyvolper = AbsValue(buyvol1) / v1 * 100;
def sellvolper = AbsValue(sellvol1) / v1 * 100;
plot buyvol = Round(buyvolper);
plot sellvol = Round(sellvolper);

But now this is what I get... just plots the current percentage and not the percentage throughout the day.

I know I'm missing something, probably simple to actually plot the percentage as the day goes on.

Just wondering if anyone can help out with this…

I know @samer800 can knock this out in a few mins. 😉

Asking for a friend!

Ruby: 
# plot percentage of buy / sell volume pressure
def buyvol = Round(((high - open + (close - low)) / 2 / (high - low)) * volume, 0);
def sellvol = Round(((low - open) + (close - high)) / 2 / (high - low) * volume, 0);
def buyvolper = AbsValue(buyvol) / volume * 100;
def sellvolper = AbsValue(sellvol) / volume * 100;

declare lower;
plot pbuyvol = Round(buyvolper,2);
plot psellvol = Round(sellvolper,2);
addcloud(pbuyvol,psellvol,color.dark_green, color.dark_red);

Can someone make this work with tick charts?

input agg = AggregationPeriod.DAY;
def v = volume(period = agg);
def h = high(period = agg);
def o = open(period = agg);
def c = close(period = agg);
def l = low(period = agg);
def buyvol = Round(((h - o + (c - l)) / 2 / (h - l)) * v, 0);
def sellvol = Round(((l - o) + (c - h)) / 2 / (h - l) * v, 0);
def buyvolper = buyvol / v * 100;
def sellvolper = AbsValue(sellvol) / v * 100;


AddLabel(yes, "Buy Volume: " + buyvol, Color.GREEN);
AddLabel(yes, "Sell Volume: " + AbsValue(sellvol), Color.RED);
 
@JDS
Scripts referencing time cannot work on tick or renko charts as there is no time axis.

Taking out the timeframe references should allow your script to work on tick charts.

Ruby: 
def v = volume;
def h = high;
def o = open;
def c = close;
def l = low;
def buyvol = Round(((h - o + (c - l)) / 2 / (h - l)) * v, 0);
def sellvol = Round(((l - o) + (c - h)) / 2 / (h - l) * v, 0);
def buyvolper = buyvol / v * 100;
def sellvolper = AbsValue(sellvol) / v * 100;


AddLabel(yes, "Buy Volume: " + buyvol, Color.GREEN);
AddLabel(yes, "Sell Volume: " + AbsValue(sellvol), Color.RED);
