This shouldn't happen. Can you let us know more about this issue?
Please let us know which version of the library you are using, your setup and some more details to debug or reproduce.

I am getting same error too.
Looks like it happens if there is a opening position with SBIN.

I am using c# SDK kiteconnect 3.0

kcsomisetty

sorry, it happens with other stocks too. (ex: IOC).
looks like a typecast exception in my case.

kcsomisetty

Hey @sujith this is blokcing my strategy from going live.
can you quickly take a look ?

this is the library version i am using.
Tech.Zerodha.KiteConnect.3.0.3.1

the base error message is
"Cannot implicitly convert type 'double' to 'decimal'. An explicit conversion exists (are you missing a cast?)"

kcsomisetty

my guess is, conversion of m2m/unrealized fields in Position.ctor

https://github.com/zerodhatech/dotnetkiteconnect/blob/a06a0cba2dd8700baaa07c52ba2d26da41565399/KiteConnect/Structures.cs#L280

is failing and throwing exception.
i might be wrong though.

sujith

Yes, this is happening because of the exponential value. We have asked the .NET client team to handle this.

@sujith
i have tested a fix locally and created a pull request.
https://github.com/zerodhatech/dotnetkiteconnect/pull/19

your team review and merge it.
