1. Revenge trading, trying to get back a trade that has been lost or chasing a trade.
I think there is nothing so wrong with revenge trading, but it should be done in a right state of mind and with well planned strategy or better still, leave the fight back for another day.
In addition to your point; leaving the market for a time is a common error as well. One needs to stick to the market, be aware of any movement and expect the unexpected.
