Amit,
I had a bit of data problem from yesterday afternoon and in my chart it was showing a PL at around 12- 12.30 in 15 min chart. When I saw vinneet's charts it was not there. Some wrong data got updated probably... any way... today all is fine ...
Entering on 15/20 min pivot if 30 min pivot is far away is very much in the system. Here one has to remember to use it judiciously otherwise it becomes a 15 min flow... We use 15 min pivot when either 30 min or 60 min or both are pointing in same direction. But our main TF is 30 min that has to be kept in mind. More later...
