Hi Artur,

Thanks for your quick reply

I tested this expression against -->   LeadLag(100,101+102@103,104)

it is allowing number after first ','  and before '@'
i.e. 101 and 102

Our string only contains + or - and then @ after first ','
for e.g --> ',+@103'  OR ',-@103'

Could you please modify the expression accordingly?

Please let me know if you need any more information?

Regards,
Mahesh
