# Consecutive Bar Count Indicator for ThinkorSwim #### korygill

Like roulette in Vegas, the longer the ball keeps landing on Red, the more likely it is to land on Black the next turn, right? Well, in roulette, the odds are the same each turn, but perhaps in the stock market, all trends change at some point. [side note on roulette]

This is also an example of how to count things in thinkscript. If you are new to thinkscript, remember that your code runs on each bar and calculates everything based on that bar and any forward or backward looking values (like close being the close 1 bar in the past). You can also reference the values of your own variables!

CompoundValue is a powerful function, and one you can use to in a couple ways. One way is counting things. That is what I will show here. Search other articles and the documentation for other usages like how to carry a previous value/condition forward until it changes.

For this example, we will count the number of consecutive up and down bars (based on close) on a chart. This image should give you a clear idea of what we're doing. Perhaps this technique can be applied to other studies and strategies. Code for ConsecutiveBarCount

plot pBarDownCount = if barDownCount < 0 then barDownCount else nan;

pBarDownCount.AssignValueColor(Color.RED);

The secret sauce
def barUpCount = CompoundValue(1, if barUp then barUpCount + 1 else 0, 0);

This statement says...
if the current bar is up
then set barUpCount to the "barUpCount of the previous bar" plus 1
else set barUpCount to zero

For now, don't worry about the first "1," and the last ",0" parts. You will just about always keep those like that and just change the middle part...

So the first UP bar we see is 1. If the next bar is also UP, then we take the previous barUpCount (1) and add 1 to it for 2. If we get a third UP bar, then we take the previous barUpCount (2) and add 1 to it for 3. Once you get this (and don't worry if it takes you a while; I struggled for a bit at first too), you will get an aha moment and this will become a great tool in your thinkscript arsenal.

Hey Kory, that is a very nice little touch that you put in; placing a version history at the top of the script. Quite professional.

Thanks. I get paid to code for a living, and I try to use best practices everywhere. I saw other scripts that have a version scheme that did not sort well. It should be real easy to see if your version is newer/older than something else you are looking at. Also I am experimenting/exploring the right amount of boilerplate at the top. I expect many scripts here get modified by everyone a little. Want to encourage sharing/extending and attribution.

Sorry if this has been answered perhaps it'll make this easier if so, but I'm just looking for a simple study that counts candles. it has to keep a running total so if we've had 4 red candles it'll say 4 red candles then 5 and flip upon green, etc.

wow awesome thanks a lot

here's the label i was trying to make i just plugged in the data from this

Code:
``AddLabel(yes, " BarCount: " +(" "+(Round(barDownCount + barUpCount, 1))), if barUpCount > 1 then color.upTICK else if barDownCount <= 0 then color.downtick else Color.gray);``

I like this one on the daily/weekly chart. I added this code in for a quick assessment of price difference since last down bar.
Code:
``````def close_diffpositive = if barUp then close - close else 0;
def totalpositive = compoundvalue ( 1,if barupcount then close_diffpositive + totalpositive else 0,0);
def close_diffnegative = if barDown then (close - close) * -1 else 0;
def totalnegative = CompoundValue(1, if bardowncount then close_diffnegative + totalnegative else 0, 0);  VIP

I know this should be basic, but I'm not getting the correct results. If I wanted to scan for stocks closing down 8 straight days in a row, is the below code wrong? If so, what should it be? Thanks for any help

sum (close < Average(close,5), 8) >= 8

Thank you @korygill for taking the time to do this and everyone else for adding their modifications, I think it is great and everyone appreciates it.

I wanted to offer a suggestion that will make reading this a lot easier:

With Labels, can you please add the % of time the consecutive events occur? For example, there would be a label "1: 60%" if the number of consecutive up events were 60%, and another would be "-1: 65%" if the number of consecutive down days was 65% of the time... this would be repeated for all of the consecutive events (2, 3, etc. for both up and down days/candles) -- this would make summarizing data a lot more efficient.

Or instead of labels, if possible, we can place these just to the right of where the indicator's title is shown (beside the other data point squares), that would save space!

I am not sure if this is possible to create, because I'm not a programmer, but I think that will be a lot more powerful! If someone is capable of adding this to the script, that would be awesome and thanks a lot in advance! Thanks!

There might be a way to get various counts using fold or compoundvalue, but I chose to just carry some variables forward and solve that way.

Now you can use a "percent" mode on another lower study to see the percent of time a given count is achieved. This is based on visible data, so the longer the chart, the better the accuracy.

@korygill thanks so much for the code. Can you please explain it a bit for us non-programmers... if I wanted to see the % of two consecutive up days, where would I find that % on the indicator? And does this segregate % two consecutive up days, and % two consecutive down days, or are both up and down days counted the same when the two days/candles are consecutive? Thanks. #### korygill

Each count is treated as it's own. +1 is a distinct calculation then -1, etc. For the 1yr of CRM, -1 is like 26.9% of all the bars visible. +1 is 27.2. Hover over the rightmost bars and see the value in the study on the title bar for the lower study. There are 5 bars that are +6 for 2.2% of all the bars from the start of the chart to that point in time.

Thanks for clearing that up, and finally, the "30", "20", "10", "5" what do those mean inside the title bar? Thanks

Just add it to the bottom of the code in the original post by korygill. It just needs to be after the def barup/bardown and def barupcount/bardowncount since those are referenced in my post.

Is there a way to code a scanner that counts the number of times a stock makes a new high after market open?

#### ext99k

Is it possible to modify this code to show the number of consecutive days the stock opened higher, lower than the previous close, the same way the % frequency was added for the # up/down days with the squares (in the most recent update to the code)? Thanks!

Last edited: #### korygill

@ext99k i think you can do this by changing
def barUp = vClose > vClose;
def barDown = vClose < vClose;
to
def barUp = vOpen > vClose;
def barDown = vOpen < vClose;
and using the study on a 1 day chart.

give it a shot, and if it does not work, i can look at the study in the evening when i am free.
