The standard deviation indicator helps you predict future price volatility. Standard deviation is an indicator that measures the size of recent price moves of an asset, to predict how volatile the price may be in future. It can help you decide whether the volatility of the price is likely to increase or decrease.
On-balance volume (OBV) is a technical trading momentum indicator that uses volume flow to predict changes in stock price. Joseph Granville first developed the OBV metric in the 1963 book Granville’s New Key to Stock Market Profits.

Hi
STD deviation is normally over a set of values. But the STD function accepts only one value. We would ideally like it to have a length parameter
In your example given, the STD of VWAP of current day close is given. it is the same as the VWAP. SO with just only one value accepted in STD calculation, it cannot be effectively used.
Or, do I miss out something here?
Apologies but your query is not very clear here. The Standard deviation has 2 parameters, one is the source and the other is the length. Here is the syntax for example for a 20 period standard deviation on the “close” attribute:
latest Std ( latest Close , 20 )
Please do let me know what you are trying to achieve here so we could assist you accordingly.
It will show the previous days/ minutes results for your scan without the need for you to modify the scan. Back-testing will not give alerts. It is only to analyze/ view stocks previously triggered by your scans. If you click on any of the bars on the graph, it will show the list of stocks that triggered as per the scan previously.
Back-test data will show data for the lowest candle time frame in your scan. If lowest time frame is 1 minute, it will show results for last 1 minutes. If its on daily candle it will show data for past 6 months. We show results for the past 150 bars in our backtest section, these 150 candles could be of any timeframe, depending on the lowest timeframe in your scan, so for 5 minutes for example, you would get 2 days, for 1 minute, half a day and so on.
If you have the alert frequency of 5 minutes on a 1 hour candle scan, the alert results will update every 5 minutes and so will the backtest results(if you open the site and view the graph every 5 minutes), the difference is that the alert keeps a history of all your stocks triggered every 5 minutes i.e at 9:20am, 9:25am and so on via the alert history page,, whereas the backtest graph doesn’t keep any history as such, it will show the results only as of the candle completion time i.e 10:15am. so its not necessary that the backtest will show all the stocks that were triggered every 5 minutes as your alert show’s.
Alerts is a premium feature that would allow you to do this, it keeps a track of all your stocks that met the condition every 5 minutes so that you don’t need to keep a track of them manually in the scanner page or the backtesting graph. The backtest is a dynamic graph that would update/change as your 1 hour candle is changing.
Please provide some details on this, any link to the scan would be appreciated. We get VWAP data directly from NSE, so it should match with VWAP figures on nseindia.com
In the example you shared on vwap and stddev, it is using latest, I am looking for 5 min or 15 min candle cross above 2 std dev of vwap.
After changing the latest to 15 min or 5 min,
The scan shows random results about stock crossing vwap instead of 2 std dev. Some results show 2 std crossed but other results show as vwap cross.
Seems some problem with either vwap data or std calculation error.
Kindly look into this as it generates false vwap crossed instead of vwap std dev
we don’t compute the VWAP values at our end & get this directly from the exchange & even if we did so at our end, there would be slight differences due to the ticks mismatch across various vendors.
The reason is, vendors, consider only a few ticks per second & these tickets could be different across various platforms. We, on the other hand, get the candle computed on the exchange & it includes the ATP/VWAP values as received & computed in the exchange, which is more accurate.
Is there any way to calculate the VWAP at chart ink platform. I will avoid the default VWAP provided by the platform and calculate the VWAP by self. I understand the VWAP value will not be 100% accurate.
The formula is:
VWAP = Typical Price x Volume/Cumulative Volume
(This can be done on 5 min candle
Where Typical Price = High price + Low price + Closing Price/3
Volume of 5min candle: =0 [5 min] Volume. This too is doable
I have 2 queries:
How to get the total (Cumulative = total since the trading session opened) volume for the session for the scrip?
Will Std Dev work on this calculated value?
—
Thanks,
Anand.
Hi Anand, You can calculate using this logic taking “Daily volume” as the cumulative volume for the current day.
Hi Sir,
Thanks for the info.
The std dev calculation is on integer numbers only.
Can the std dev take floating number (decimal numbers)?

Thanks,
Anand

Currently we support only NSE cash stocks and indices. We do plan on adding others soon. Shall keep you posted. Currently its not really possible to give an ETA on the same.
This is possible. If you are running it on a 30 min candle, you can select [-1] 30 for the previous candle or view past results history in the back-test feature.
good morning sir
i am the premium subscriber
i made one scanner (5 min time frame.) and i want run that only between 10 am to 02 pm is it possible ?
presently all 5 min time frame scanners starts giving alerts from 0915 am
hi chartink i would be happy that your screener are not giving real time data inspite of having premium subscripstion so i am not getting real time alerts also. kindly do needful to resolve the issue. thanks
This could probably be because of a scan or an alert misconfiguration, which we could investigate and correct; please share the following details:
1. URL of the scan that you are referring to?
2. Share a few example stocks with us for which you should have received alerts but did not get alerts for the same.
3. Share a screenshot of the alert settings for your scan. You can do so by opening your scan and clicking on the “modify alert” option and sharing a screenshot for the same here for our reference.
What is it plz explain

Scanner in commodity section…will it be available…
Also total buy and sell scanner if added will be nice..
Currently we support only NSE cash stocks and indices. We do plan on adding others soon. Shall keep you posted. Currently its not really possible to give an ETA on the same.
You can start by reviewing out top scans here: https://chartink.com/screeners/top-loved-screeners
They contain the top 10 scans used for Intraday/Swing & short term trading
Thank you very much for including OBV in scanner.
You are most welcome.
Please add Fibonacci pivot points
It is possible to use these in our scans using the formula. Below are a few example scans:

https://chartink.com/screeners/search?search_term=trendline
No this is not sir. See in tradingview website we can draw a trendline and also keep an alert for the same. Kindly check that once and add
Ok. Shall get with the team on the same.
OBV is not working , Just “OBV < 0 " itself giving wrong answers 🙁
We are looking into it, shall update shortly.
Thanks
Most welcome
when will you implement previous candle cross over
why it is so difficult
thanks
This is possible. If you are running it on a 30 min candle, you can select [-1] 30 for the previous candle or view past results history in the back-test feature.
good morning sir
i am the premium subscriber
i made one scanner (5 min time frame.) and i want run that only between 10 am to 02 pm is it possible ?
presently all 5 min time frame scanners starts giving alerts from 0915 am
Hello,
No, currently we cannot set a time range to run scans. For now, this is something which needs to be done manually.
Hi sir,
I want become premium member, it will automatically update for 1,3,5 min charts after payment ??
Is it available COI live data in chart
Yes. its an automated process. It is activated immediately. What do you mean by COI?
Sir,
I want to run a screener for volume spikes.
logic is as follows
volume > 2 standard deviation of 20 moving average on volume chart.
how to do it?
Below is your scan:
