DECLARE @date_start DATE, @date_end DATE,...

RE: Date Validations?

Can you provide more information about the context please Ananth? For instance, are you designing a validation process for an import of a text-typed date?

RE: SQL How to use CASE with a NOT EXISTS statement

There's scope for improvement but without ddl/execution plan it's a long shot. Try this:
SELECT
t.TradeId,
CASE WHEN x.OtpTradeId IS NULL THEN 'Y' Else 'N' End As 'TCM'
FROM Trade t
OUTER APPLY...

Curious...ok, paste this whole batch into a new ssms window and execute:

@RangeStart = x1.MondayLastWeek,
@RangeEnd = DATEADD(DD,7,x1.MondayLastWeek)

Point taken Chris, but even if I did I wouldn't get results as I don't them in in the SSMS query?
Check:
SELECT TOP 100 Docket_EngFinish
FROM DocketTB
ORDER BY Docket_EngFinish DESC
