In the article of 30 days challenge , it says that client have to profit 1000 minimum to win. But down in that article photo says that someone won the challenge only in 11 profit. Please clear that do we need to profit 1000 or more or do we need to be just profitable. Thanks

Net profit/loss = Gross profit/loss - expenses

And yes your question is valid. I think it is based on the previous/past terms and conditions.
I'm not sure though. 


Check with @Vanshika Singh17 @Tejas Khoday18 

For getting the certificate it is enough if you are net profitable, but if you want brokerage refund too then you have to make a minimum net profit of Rs 1000/- 

That Rs 1000/- requirement has also changed recently to minimum Rs 3000/-

For more details refer the blog on the recent changes.
