Hello Gary,
Thanks for the pointer that my code was blocking the first bar of the
day, I hadn't noticed that before,
if Time = Sess1FirstBarTime works fine but
if Time crosses over Sess2EndTime does not ?
and to David who suggested using session2 this was the main fix here
Changing Sess1 8:00pm - 4:00pm Sun to Fri
To Sess1 8:00pm - 12:00pm Sun to Thurs
Sess2 12:01pm - 4:00pm Mon to Fri
GF> What exactly are you trying to do? With RTH-only data (Regular
GF> Trading Hours, not including the overnight session), that test
GF> blocks the first bar of the day. It's equivalent to
GF> if Time > Sess1FirstBarTime
I was using that code to define each days data and to reset variables
for the next day, an example is, when using a variable tracking the
highest high of the day, resetting it from the highesthigh yesterday
to the high of Sess1FirstBar
GF> What data are you using?
The data is CBOT a/c/e financial data which does start at 8:00pm till
4:00pm the next day.
Like the SP and ES, the ZB symbol trades through, and at the same time
as the US (regular trading hours) symbol trades, the CBOT appear to
treat this as all one session, but TS needs 2 sessions to handle the
date change.
best regards,

If StartTime >> EndTime like this, you need to change your test:

GF> That's true for all bars after the first one at 8pm, and for all

GF> You could write your code to work for either case:
GF> if Sess1FirstBarTime < Sess1EndTime
GF> then OKbar = (Time > Sess1FirstBarTime and Time <= Sess1EndTime)
GF> else OKbar = (Time <= Sess1FirstBarTime OR Time > Sess1EndTime)
GF> if OKbar then ...
GF> What data are you using? For 24hour e-mini data,
GF> Sess1FirstBarTime is 835 (Chicago time). Session 1 is normally
GF> the Regular Trading Hours session, and Session 2 is normally the
GF> overnight session. Are you sure Sess1FirstBarTime is 2000 (8pm),
GF> and are you sure it should be?
GF> Gary
