@tarunjune21, Yes...Thats a bit stetched....:) The reason is I found the pattern quite late and also the lowest green candle formed on 3-April-2017 is having a low of 846. And as per ideal pattern of 3 drives we need to keep the SL below the completion of the 3 drive i.e. in actual less than 830 which would be too much so just keeping it tag below the next candle .
Downside 888.8 - 840 = 48.2
