Backtest results FAQ

Backtest results will update or repaint thru the day while the current candle is being built up. Below are the scenarios that should be considered while validating results from the backtested history.

Example 1 (Single timeframe – Daily candles)

A scan running on a daily candle, shown at 10 am, will differ from the results displayed at 12 pm. This is similar to how the indicators/candle would look for the current day on a candlestick chart, i.e., it will continue to change for the day until the market is closed.

Example 2 (Multiple timeframes – 5 minute and Daily candle)

For a scan using 2 different timeframes, i.e 5 minutes and daily candle, the backtest history would show a bar for every 5 minutes(lowest timeframe in the scan), the backtest history would spread the daily candle for every 5 minutes, i.e., the values current spanshot of the daily candles is spread across all 5-minute bars in a day causing the results to change as the current version/snapshot of the daily candle updates.

Unlike Alerts, Backtest is generated on the fly(i.e., the time you view the scan). E.g., If you view the backtested history on such a scan at 12 pm and then re-check it at 3 pm, the backtest bars since market opening, i.e., 9:15 am, 9:20 am, and so on.. may show changed/updated results as the run on 3 pm saw a newer version of the daily candle, as of 3 pm. In such a case, to validate the actual stocks present in a scan at 9:30 am, would be to create an alert and validate the results of the alert’s history instead. As alerts run on the trading time (9:20 am, 9:25 am, 9:30 am), unlike backtest, generated on the fly, i.e., when you view/open the scan page.

Note: This behavior is NOT a bug, but rather how candlestick charts are shown/displayed, the candlestick chart show’s only the current version of the candle and not how it looked every second/minute in a day, which would mean the current candle on a candlestick chart would continue to change/update thru the day while the candle is incomplete

    1. For “1 day ago” it will be the completed candle. For the current day(i.e daily candle using “latest..”), it will change/update until the current day’s candle complete

          1. Hello,

            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. Or the alerts you received disappeared from the backtest.
            3. Share a screenshot of the alert settings for your scan. You can do so by opening your scan, clicking on the “modify alert” option, and sharing a screenshot for the same here for our reference.

      1. For a lot of times even after the market is closed and backtested results are collected, next day either the stock gets disappeared from the previous day list but it still stays in the csv file that is downloaded. Also, have noticed stocks getting added in the list. Can you help me?

        Reply

        1. Hello,

          The reason you see this is because your scan is using the 1-hour and daily timeframes, and you are running the scan in between the day. This will cause the scan to show you results based on an incomplete daily candle. The backtest results will continue to be repainted/updated until the daily candle completes its formation.

            Thanks for this reply just need to know further on this that the statement you have made “The results in the backtest will continue to repaint/update until the weekly and monthly candle completes its formation.”
            Does it mean, for any chart when we use Mothly/weekly candle in the screener
            “The best possible date for a backtest to be consider could be the result wahich was shown for the 1st of every month….?????????”
            please please reply on this thanks in advance..!!

          2. Hello,

            No rather the end of every month in case of the monthly timeframe. On the 1st of the month the candle would only have data of the 1st day whereas on the last day of the month, the candle would be a completed monthly candle containing data from the 1st until the last day of that month.

    1. This is rather a behaviour that you notice on candlestick charts as well. A better way to track/test a scan would be to ensure filters of higher timeframes like daily don’t impact/cause the results to change on a lower timeframe. Often we see queries like “Latest volume > sma..” which delays the result of a scan even if lower timeframes like 5 minute filters meet you conditions.

  15. Hi Team,

    You guys rock and are already doing tremendous work.

    A suggestion :
    For better backtesting, below timeframes for parameters like Open/Close/High/Low would be helpful. These can be made available for previous day/week candles as applicable. They will have values if those many days/weeks have passed. Else it’ll have ‘NaN’ or 0.
    1. 1 day after, 2 day after …. 5 day after (These would be particularly helpful)
    2. 1 Week after …
    3. 1 month after ..

    Any support in this regard would be much appreciated.

    Reply

    1. My observation & practice

      When I use Latest, Weekly, Monthly, I’m clear it is the OPEN CANDLE of the current Day, Week & Month respectively

      Thus the results will keep coming & disappearing as the the signals will be true at some moment in time and not match in some other moment in time and since these candles are working on OPEN CANDLE, my expectation is to catch the signal as soon as it happens and thereafter it may disappear if the conditions are not true anymore

      For E.g.
      at 10 AM Latest greater then Latest SMA 20 and I got the stock on my scanner
      However at 11:35 AM Latest was less then SMA 20 so this stock will disappear from my scanner

      Same is the case for weekly and Monthly
      at 10 AM on monday the Weekly is Greater then Weekly SMA 20 so I will get the stock in the scanner on Monday

      However, on Thursday, the Weekly is Lesser then Weekly SMA 20, so I the same stock will disappear from the scanner

      So, use Latest, Weekly, Monthly only when you want to catch signals on the CURRENT OPEN CANDLE
      Otherwise always use 1day before, 1 week before and 1 month before

      One e.g. of proper usage can be
      1 day ago Daily less SMA 20
      Latest crossed above SMA 20
      Now, this will ensure that the previous day candle close was below SMA20 AND current Daily Candle has crossed above 20SMA

      Note: this again can disappear from the scanner later in the day if the Current Day Candle comes below SMA 20

      Hope this helps sort out the confusion

      Thanks

      1. Thanks Sandeep. This is good practice indeed. As you mentioned, it helps if we work on finished/completed candles as we can see same results when we backtest.
        What I wanted to achieve is real backtesting where we can see how our scan results performed in x minutes/hours/days after those appeared on scan. This way I can backtest and optimize my scans further/faster.
        My earlier message is suggestion towards achieving this.
        Please add. Also hoping that Chartlink support team would take a note and guide in this regard.

  30. Hi
    I am a paid subscriber. Currently when we backtest a monthly scanner (or any) for historical duration for example last 10 years, and use a filter for NIFTY 500, it always uses the latest NOFTY500 stocks even for historical months. This leads to significant errors for backtest results and return calculations for historical months for a specific strategy. Ideally the back test SHOULD use the NIFTY 500 stock list for the specific historical month as filter instead of using always the list NIFTY500 stocks of the latest month . Example if the backtest is generating result for the month of 2015 March, it should use the stocks present in NIFTY 500 index as on March 2015. Currently it always uses latest NIFTY 500 stock list (for example June 2022) even for older historical months. So can you please confirm when you will fix it? Till that time any long term filter/idex filter based strategy backtesting is not useful in Chartink.

    Thanks in advance.

For example, if your scan only uses the daily timeframe, the backtest will contain the backtest bars of every day. Similarly, if your scan uses the 5-minute timeframe, the backtest bars will show all the 5-minute bars throughout the day. I hope this helps.

  39. Hi Akash,

    I have an Alert set against a particular Scan. What I find is, the Alert page indicates less no. of triggers (stocks) as compared with the backtest results of the Scan Page. The Scan is on a single time-frame, which is 5 minutes, and the Alert is set at 5 minutes interval.

    For Eg. at 2:00 pm : Alerts page throws up Axis Bank, AmbujaCem, VEDL,
    So does the Backtest results of the Scan page .
    at 2:10 pm : Backtest result of Scan page throws up AmbujaCem
    but Alerts page does not show any triggers for 2:10 pm

    Why is this happening?

    Reply

  40. So essentially, all your backtesting with multiple timeframe analysis will have a forward looking bias because while I’m planning for the entry at 5 min, looking at the daily value of an indicator at that moment, your backtest results looks at the daily value of the indicator at the close of that day.

    It might not be a bug, but it makes your tool useless for multi timeframe backtesting. Doesn’t it?

    Reply

    1. Hello,

      The reason why you see this is that you are using multiple timeframes in your scan; how the scan works are, say, for example, you write a condition as below:

      5 min close > -1 5 min close
      and Latest RSI (daily candle) > 60

      When you run the scan at an example, 10:17 am, A stock ABC supposes having the latest 5 min close value is 100, and the previous 5 min close value is 99. This fulfils the 1st condition. Now suppose at 10:17 am, the latest RSI value, i.e. the daily candle RSI, was 64; now, this also fulfils the 2nd condition. Hence the stock ABC will be displayed in the results.

      Now say if you run this same scan at 11:06 am (around 1 hour after the first run), the values that the 2nd filter would see, i.e. against the daily candle, would be as of 11:06 am (& not as of 10:17 am), this would cause the backtest results to change/update/repaint because the daily candle impacts the results of all earlier time’s shown in the backtest (i.e. for the current day as the daily candle is not yet complete).

      Note, this is the same behaviour that you’d notice on a candlestick chart, i.e. viewing a candlestick chart on a daily timeframe at 11:06 am would show the RSI or any indicator value as of 11:06 am and not the values that were present at 10 am or 10:30 am and so on.. this causes the backtest results to change/update.

      I hope this clarifies the confusion here.

  46. Hi great work chartink team i wanna ask a question
    If i set condition weekley atr greater than atr 1 week ago
    Will the result displayed on monday be thesame throughout the week or will any change in middle of week affect result of that generated on Monday.

    Reply

    1. Kindly note that if your scan is using the weekly timeframes and you are running the scan in between the week. This will cause the scan to show you results based on an incomplete weekly candle. The results in the backtest will continue to repaint/update until the weekly candle completes its formation.

      The weekly timeframe contains the data from Monday to Friday, and it will completed on Friday at 3.30pm. Till then, it will be continuously updated.

      I hope this helps.

    1. Hello Varun,

      Thank you for reaching out. The reason you see this is that your scan is using the monthly timeframes, and you are running the scan in between the months. This will cause the scan to show you results based on an incomplete monthly candle. The results in the backtest will continue to repaint/update until the monthly candle completes its formation. I hope this helps.

    1. Hello Varun,

      It seems like this is the same scan from the previous comment. The reason you see this is that your scan is using the monthly timeframes, and you are running the scan in between the months. This will cause the scan to show you results based on an incomplete monthly candle. The results in the backtest will continue to repaint/update until the monthly candle completes its formation.

  49. Hi Shubam, agree with your point if the results disappear from the backtesting list.
    But how will it get added to results once the date has passed? As per your logic , results are updated in last day of week or last day of month. can you take the above scan and explain reason why WELSPUNIND appeared on 19-oct-2023 please? I am not understanding this.

    1. Hello Varun,

      Please allow me to explain in more detail. I will take an example of stock “WELSPUNIND” showing from 19-10-2023 in the scan backtest.

      If you noticed, your scan has different daily, weekly and monthly timeframes. On 19-10-2023, the stock “WELSPUNIND” probably fulfilled the daily & weekly conditions except for the monthly timeframe condition criteria.

      Due to this, if you run this scan on 19-10-2023, this stock won’t appear in the results, nor will it be there in the backtest results.
      Now, say on 31-10-2023 (today), the same stock fulfils all the group conditions daily, weekly and monthly.

      Since all conditions have been met, this stock will show in the results from 19-10-2023. It caused the backtest to repaint and add the stock “WELSPUNIND”. Because the backtest uses the highest time frame (monthly in your scan) and spreads the bars for the lowest one. If you notice in your scan, the backtest will show the daily bars (lowest time frame in your scan)

      I hope this helps clear up the confusion.

    1. Hello,

      The LHS side of the comparison operator seems to be incorrect. You are comparing the daily RSI with the maximum RSI of 5 days, which includes that daily RSI. This won’t give you accurate results, as you need to exclude today’s RSI value.

      Can you please confirm if you want the RSI divergence? If yes, please share a sample chart image at [email protected] and we will create the scan for the same.

      You may ignore backtest results for this scan as it is not always accurate due to multiple time frame candles used in the scan; this is because the backtest uses a higher timeframe candle that would spread for all bars within the backtested history, so as long as the higher timeframe candle is incomplete, all bars in the backtest would too change/update.

      In contrast, the alerts you receive for this scan are accurate and sent instantly once any stock matches all scan criteria as long as the lowest time frame in the scan and the alert time are the same.

  55. hi, i have a scanner but i only want a stock which comes in moring between 9:15 t0 9:20 i dont want for whole day stock ,, can you help me with this.

    1. Hello,

      This can be done with the help of a custom indicator/formula. Here is an example scan for your reference:

      https://chartink.com/screener/10-year-break-out-4

      Note: The Market cap field is normalized. So the number 100 against that field would be 100 crore. 

      To use this custom indicator, you can “Copy scan” scan & make changes. You can view the logic of the custom indicator by clicking on the purple sign(>>) next to the indicator.

      Also, you can create your own custom indicator by copying/pasting the logic from the indicator shared here https://chartink.com/indicator

      Once you create your custom indicator, it should be visible in the dropdown list under “derived/custom indicators”. Here is a short video on how this can be done.: https://drive.google.com/file/d/1bnr1ahmajyXIpBRE69ese60sm7541-14/view?usp=sharing

  57. This is my scanner,

    ( {57960} ( monthly close > 1 month ago high and 1 month ago close 1 week ago high and 1 week ago close latest ema ( latest close , 4 ) and 1 day ago close <= 1 day ago ema ( latest close , 4 ) ) )

    I expect this to list all the stocks which meet the criteria. But most stocks only appear in the backtest and I never get a chance to verify it in real time.

    How can I improve it, I want to see the stocks which meet the criteria on monthly, weekly and then daily time frame.

    1. Hello,

      The backtest results would reflect the time only if your scan condition contains intraday timeframes. If your scan only uses the “daily” timeframe, your backtest results would only show the backtest bars in “days”.

      In order to view the time, you could add intraday conditions as well within your scan.

      I hope this helps.

  66. Hi,

    I want some help in understanding this…I have created a sample query which showcases the problem im facing.

    https://chartink.com/screener/query-for-chartink-support

    for this scanner, in backtest u can see that this stock is present, BHARTIARTL > Largecap >19-09-2024 12:15 pm but i didn’t get any alert for the same.

    Secondly, in create scan or scanner page, this is the rule
    [0] 5 minute Close crossed_above 1 day ago High
    latest Close > latest Open

    but when u see the rules in the dashboard, im getting like this
    ( nifty 500 ( [0] 5 minute close > 1 day ago high and [ -1 ] 5 minute close latest open ) )

    I want to understand and [ -1 ] 5 minute close <= 2 day ago high this part as i didnt add this anywhere and its getting added automatically

    1. Hello,

      To check this, we’d need to review the alert settings of this scan. Please share a screenshot of the alert settings for this scan. You can do so by opening the scan and clicking on the “modify alert” option and sharing a screenshot for the same for our reference. You can directly share the screenshot via email to “[email protected]”.

      To answer the 2nd query, the crossed above function is being used incorrectly here as we can’t use the crossed above function while checking 2 different timeframes.

      A crossed above function checks for the latest candle to cross which means if you are checking for stocks where RSI crossed above 60. Internally it checks for the current candle’s RSI to be more than 60 and the previous candle’s RSI to be less than 60, thereby signifying a crossover.

      I’ve modified the scan correctly. Here is the link for your reference – https://chartink.com/screener/query-for-chartink-support-v2

      I hope this helps.

    1. Hello, Please note that backtest bars are always based on the smallest time frame you choose in the scan. A bigger time frame will allow you to access more data, while a smaller time frame will limit the data you can access.

      Below, I’ve included a list of scan timeframes with the corresponding maximum backtest period –

      5 minutes – 3 Weeks
      15 minutes – 3 months
      30 minutes – 7 months
      1 hour – 1  year & 4 months
      Daily – 5 years.
