Gidday Tom,
One possible reason (as a rough guess):
- assuming you are using intraday data of same kind
- in chart mode you have daily view selected i.e. view market hours only ... so charts automatically 'ignore' after market hour data?
- in BT mode,you have to specify, via code, if you want to ignore after hours data i.e. data that comes in after the defined market hours (see your database settings for defined market hours ... this is defined on a market by market basis)
If this is the case:
- in RT data market hours can be defined, via code
timenum() >= 093000 and timenum() <= 160000;//data from 830am to 4pm, inclusive will be used.
OR check your DB settings and select 24 hour view if you don't specify market hours via code.

When the bar closes late, sometimes, I will have a trade signal generated at the close when it was not generated until the late sale.
