When a user enters an end date older than purchase date, the tiingo api resonse is empty. In that case what should we consider as ending date? I am not getting this even after thinking a lot. @AmoghaKS @Kiran @shoryajain @akashchhetri Can you guys help a bit?
No test cases deals with that, and also think logically it doesn’t make sense right? You don’t have to deal with any such case, so chill 
@jyotirmoy-paul In the previous thread of similar problems, I read I was supposed to take care of this corner case. My mainCalculateReturnOldTrades test and mainCalculateReturnVaryingDateRanges test case is failing.
I have taken care of case where the no. of year is less than 1 and have done correct sorting.
I didn’t know there was no test cases dealing with that and did spend a lot of time on it 
Anyway I handled such cases by using simple “if” … was handling empty result by API. (I think you need not worry if they aren’t considering such cases)
And Even I had many build failure for the same testcase, I was making mistake in calculating the value of annualizedReturn,(you need to be very careful in calculating that…it looks simple, but we tend to make silly mistake in that…am telling cz I did 
)
@AmoghaKS I have used the approach mentioned in that post and even get correct results while debugging. I have dealt with the case where numbers of year is less than 1 but still test case are failing! 
how did calculate annualized returns?
Go through it again…you have dealt with it when it was less than year…but how did you calculate when it was more than a year. follow similar pattern when finding number of years.
if you have used 365.0/days in first case. You really need to keep that in mind when you calculate the number of years
I don’t think that’s logically coherent. Relax and try to start from basics only. Where could the calculations fail. There is a long discussion thread between @AmoghaKS and me. Go over it. We went over a lot of things and that’s how he solved it too.
@AmoghaKS Yes bro. I have done that. I have taken if else case like:
if(year<1) then use 365.0/days formula and take care of float values and if the year is greater than 1 then use orginal formula taking care of float values i.e 1.0/no.ofYears . I am doing similariily in both cases.
@shoryajain I went through your thread. I made sure to implement the points you mentioned but even then I am getting those two test cases failed. Infact, while debugging it shows right answer
you used 1.0/noOfYears ,well
I was making mistake in finding the noOfYears…well how are you finding that value, if you are doing a simple subtraction for getting that its an error
I think you need to delete it…I only asked you to express it in words.
No probz
Just have some break. Go through all the above answers carefully. You’ll definitely find the right way (itz simple but tricky 
)
Was I doing any mistake there?
there was 1/years…but I have no idea how you are calculating that (check itz not there in your SS )
So I can only tell you to reconsider the way you are calculating that. cz I strongly feel you are making the same mistake as I did.
Actually, it was 1.0/years but I will see once again though! Thanks for helping!
am not telling you 1.0/ years is wrong… Did I ever say that?
am only stressing on the way you calculated noOfYears

Okay, I will see once again!
post must be atleast 20 characters it seems.
have some rest and do it tomorrow man
Seems like one! Sure will do!
