Which is the best platform for Trading i.e. which never fails.
The worst is ICICIdrect.com. If the person is engaged with ICICIIdirect.com, it is next to suicidal, as it fail in every 10 minutes. And when it is working, even to place an ordinary order would take 5-7 minutes (provided you are lucky and it does not fail in between) and within this 5-7 minutes every thing (rate) would change.
