does it mean you avoid taking trades between first 30 mins of the opening session?
I personally have not traded before 9:45. but my trading plan includes how to trade it.
1 min opening bar hi/lo can be used as OR.
If 3 tf means first bar hi/lo..
If bias is positive wait for upward bo. vice versa for short.
exit can be 2R or u can ride the trend... ISL is opposite side OR low/high.
