Backtestable Open Range Breakout ( ORB ) Study for Amibroker

5 min read

The main challenge with the classic ORB Study for Amibroker is that it generates too many signals on the intraday charts and backtesting is not possible with such a study. This problem has been overcome by Mr Dinesh Tarte by fine tuning ORB study makes the code backtestable

ORB Trading rules
1)Buy after 11.15a.m if the market crosses above ORBH ( ORB-High) and exit logs at 150pts profit in case of banknifty or exit around 3.30p.m or if the stoploss ORBL ( ORB-Low) hits.

2)Short after 11:15a.m if the market crosses below ORBL ( ORB-Low) and exit shorts at 150pts profit in case of banknifty or exit around 3.30p.m or if the stoploss ORBH ( ORB- High) hits

Backtestable ORB


What does this code do?
Sample ORB strategy is shown above over Bank Nifty April Futures Charts. Where the Green and Red arrows indicates Buy and Sell Signals Respectively. And the Green and Red Star indicates Buy Exit and Sell Exit Respectively.

The ORB Study calculates the high (ORBH) and low (ORBL) between the first two hours i.e. from 9.15a.m to 11.15a.m .It takes the signal descision when the market cross the range on or either side after 11:15a.m. The below parameter in the code mentions the market open, close time and signal breakout time. Here signal breakout will occur only if the ORBH and ORBL break out after 11:15a.m.


The code has been optimized for Bank Nifty and it also exits at profit (say 150 points in case of Bank Nifty). However you can change the values according to your favorite stock/index. The following code decide the target point


Stop Loss Hits in Case of Two Conditions

1) If the 1st signal is active and market breaches the stoploss i.e ORBL is the stop loss in case of active buy signal
and ORBH is the stoploss in case of active sell signal

2)The position will be closed at the end of the day .

This system is purely optimized for bank nifty and consider the lot size of 50 (2 lots) in case of Bank Nifty. This code can be used with high beta stocks like SBI and others and fine tuned with the break out time like first 1 hr or ½ hr depending upon your analysis and experience with ORB study.

Amibroker Settings

The following settings is mandatory for this code to work properly.

Goto->Tools->Preferences->Intraday and Set time of first inside tick bar as shown below

  6. Hello friend,
    Would like to know, the candle time which needs to be set in for this code to work well.

  7. Dear Sir

    Pl. reply

  8. hello

    i am very much thankful for this code ..sir please help me ..every thing is perfect i am using this for nse future .so please tell me that instead of setting traget profit interms of point just by percentage .means 1 %, 2 % so that when the signal gives buy or sell signal it shows the profit target by percentage set by any user…

    1. dear sir

  10. Hi Sir,
    i am trying to import this into amibroker but its showing some error is:

    Error 32.
    Syntax error, unexpected IDENTIFIER. Is there semicolon missing at the end of the previous line?

    Use ‘Edit Formula’ to correct error”

    could u help out
    Thanking u

  11. Hi,
    Only candlestick bars are showing but buy/sell signals and ORBL AND ORBH lines are not showing solution please,, i changed setting as per u but still its not showing.
    Thank u

  12. I know im a little late in looking into this strategy so if someone is still looking into this thread do pitch in..
    I wanted to integrate this with a custom strategy of my own so wanted to understand the parameters pointed to below :

    Market_Start_Time=091500; <<< ———————- Opening of the Market.
    Market_Open_Brakeout=111500; <<< ———————- Duration upto which you would like to identify the breakout Range.
    Market_end_time=151500; <<< ———————- End of Market for Intraday players i believe.

    //need to consider 60 min insted of 100 //Market_Signal_time=Market_end_time – Market_Open_Brakeout;
    Market_Signal_time=033000; <<< ———————- What is this for ? Does this need to be changed. Why do you reference 100 here ? I did not understand how you came up with the value 033000 and what it means.
    Min_in_signal_time=2190; <<< ———————- No idea on this as well.


    I am asking the above questions because im unable to interpret what needs to be changed if i change the breakout duration. Also the backtest does not produce any results, i use AB 5.6.

  13. End of day is finding out based on next bar date. So next bar will come only in the next day. So what will happen is exit signal will show in the days end bar only when the next day is started.

    EndDay = (Day()!= Ref(Day(), 1));

    Instead we can make a time based exit. That will work correctly I hope.

    Replace the above code with

    EndDay = (TimeNum() >= ParamTime(“Exit Time”, “11:15:00 PM”));

    This will exit the position at 11:15 PM.

    1. I optimized for Mcx Its Working Great Change Market opening 10 And Breakout on 10:15 Crude Target 10 points Zinc 50 paisa Ng 80 paisa Copper 2 rs lead 50 Allu 40 paisa Gold 28 point Silver 100 All Trade Ends on 12 clock Awesome

    Kind Attention: Mr. Dinesh Tarte/ Rajandaran,

    With reference to above, sir would like to point out that your candle signal for Buy is executing at the “High” parameter instead of “Open” of the next candle. And vice-versa for short/sell.

    Can you please correct this code and upload the corrected version.
