Coding Help for Welkin's Advanced Volume Indicator.

[fungus12]

Hi I have a question on how to code something in Welkin's AVI. Here is the link to the thread for the script https://usethinkscript.com/threads/advanced-volume-indicator-for-thinkorswim.1665/

My question is about the buy/sell str for the second aggregation. First off let me just present two images so you know what I'm talking about.

Here is the indicator with the second aggregation turned off:

And here is the indicator with the second aggregation turned on:

My question is, is it possible to have some kind of percentage present in the second image that indicates the percentage of buy vs sell shown in the clouds? For example in that image from 6:30 - 7:00 it would show something like "95% buy/5% sell", then at 7:01 it would show "60% buy/40% sell". Something like that. I would prefer this also be favorable to backtesting. In other words, have the percentages present not only at the most current data but historical data as well.

Also along similar lines, I also would like to change the watchlist column in Welkin's post to show the buy/str for an aggregate (15m, for example) instead of just current bars. Here is the code in the thread for the watchlist:

#Buy/Sell Strength Column
def o = open;
def h = high;
def l = low;
def c = close;
def PR = h - l;
def BuyStr = ((c - l) / PR) * 100;

AddLabel(1,Round(BuyStr,1)+" | " + Round(100-BuyStr,1)+"%", Color.BLACK);

AssignBackgroundColor(if BuyStr >= 70 then Color.Green else if BuyStr > 50 then Color.DARK_GREEN else if BuyStr <= 30 then Color.RED else if BuyStr < 50 then Color.DARK_RED else Color.GRAY);

I wish Welkin was around to answer these questions but he's been inactive for several months now. If anyone knows how to code these things, please let me know. Thanks in advance.

Hey everyone, I'm looking for help modifying the code below. Basically I want to
plot the a cumulative line of the buy sell percentage indicator shown in the top
left of the screen by indicator below. For example on a 1 minute
chart the 1st bar is 60% buy and 40% sell = ( 20% buy ) and the next bar is 70% buy
and 30% sell = ( 40% buy ) I would like the plot to show 60% Buy. Looking for
each bar to add or subtract from total of the day. Also would like to be able to choose
RTH or ETH if possible. Have done some coding but cant figure out how to do
cumulative data. Any help would be appreciated.

Here is the code:

#Advanced Volume Study
#[email protected]
#v5.22.2020
declare upper;
input ShowVolumeAsCandlesticks = no;
input ShowBuySellStrengthOnVolumeBars = yes;
input ShowBuySellStrength2ndAgg = no;
input AvgDayVolLength = 5;
input AvgVolLength = 20;
input ShowDayVolLabel = yes;
input ShowBarVolLabel = yes;
input ShowEthTotalVol = no;
input ShowBuySellStrength = yes;


input VolAverageType = AverageType.SIMPLE;


def NA = Double.NaN;
def PriceRange = high - low;


#Current Candle Buy and Sell Strength
def BuyStr = ((close - low) / PriceRange) * 100;
def SellStr = ((high - close) / PriceRange) * 100;

def AlertUp = BuyStr >= 90 ;
def AlertDn = Sellstr >= 90 ;

def AlertRangeUp = BuyStr <= 90 ;
def AlertRangeDn = Sellstr <= 90 ;

def AlertChoppyUp = BuyStr <= 60 ;
def AlertChoppyDn = Sellstr <= 60 ;



#current candle Buy/Sell strength labels
AddLabel(if ShowBuySellStrength then 1 else 0, " ", Color.BLACK);
AddLabel(if ShowBuySellStrength then 1 else 0, "1", Color.black);
AddLabel(if ShowBuySellStrength then 1 else 0, "Sell " + Round(SellStr, 2) + "%", if SellStr > BuyStr then Color.RED else Color.RED);
AddLabel(if ShowBuySellStrength then 1 else 0, "Buy " + Round(BuyStr, 2) + "%", if BuyStr > SellStr then CREATEcolor(0,102,255) else CREATEcolor(0,102,255));

I'm intrigued by Welkin's MTF Volume Strength Oscillator (https://tos.mx/UVAhSKz) ,called out in this thread (https://usethinkscript.com/threads/advanced-volume-indicator-for-thinkorswim.1665/#post-22856).

This is the study parameters

Just so I am interpreting this study correctly, the BSDiff plots the difference (Buy-Sell) for the current chart aggregation , BS2Siff plots the difference between cumulative Buy & Sell for the aggregation2 period and BS3Diff plots the difference between cumulative Buy & Sell for aggregation3 periods.

If thats the case, when I turn off the plots for Bs2Diff and BS3Diff and only plot the BSDiff , I get this plot

Dont understand the additional plots(pointed in the screenshot).. a Single BSDiff plot should have either a Green(Buy greater than Sell) or RED(Sell greater than Buy) at a given point in time .,not both, right?. I see two plots here.

EDIT: Infact, I turned off all the plots on the study and it still plotted , as shown above. Looks like the study is hard coded to plot two of the aggregations.
Can someone pls look into the code and fix it, so it only plots the BSDiffs, as configured in the inputs.


Thanks

Any assistance pls?

Any assistance pls?

Check/Uncheck the plots you want at the input screen as you indicated.

The colored areas are clouds through the addcloud() function. There are 2 in the code. Comment (#) out the one you do not want as follows for the aggregation you do not want. For example, the higher aggregation:

#AddCloud(BS2Diff, zeroline, Color.GREEN, Color.RED, no);

 

[uTSusr07A]

Any ideas pls?

When I click on the Volume scale on the right and drag, the whole study compresses and does move the bars/plot below the labels, as shown below..,but it changes the scaling on all the studies & main chart(including price chart scaling reset to manual). Also the zero line moves up to middle of the study and compresses the bars/plots which is not desirable.

Chatted with TOS support, but no use. They suggested the script needs to be fixed..,as I dont have this scaling issue with any other study.

Thanks

Found a solution myself.. the issue seems to show up when this study is plotted in the Volume sub-graph. Moved it down as a proper lower study and the vertical scaling issue seems to have been resolved..

Another thought,
Partition Labels into another frame.
I think you can potentially reorganize your charts by separating labels from the graphs.


Interesting chat, could you share the link when ready? Also, how do you use it ? In combination with which indicators?

Thanks for the idea, will try.

yes, in combination with few things(S/R levels,Pivots,Orderbook imbalance,Momentum,Higher timeframe alignment).

Wondering if someone can help adding a treshold level for the Sigma 3 volume filter. So i would like to hide bars that meets the Sigma 3 condition IF they are below the treshold level. And the treshold level is x amount of shares traded on the current bar.

Thanks in advance

In case anyone was interested, I made a Mobile version that will show pretty much everything in the standard indicator just obviously due to the extreme limitations of the mobile app, it won't be as pretty.
You'll have to manually change the plot settings (volrel, Avgvol, volsig2 and volsig3) to triangles and color them accordingly.
I did change these lines because of my location

The "VSigX" plots in companion study need to be changed to 'HORIZONTAL' in settings to display correctly. In the below screenshots I turned volume off to highlight how the total buy/sell trades display.


And below is the scanner for volume sigma levels and buy/sell strength
