* Over trading-- it's very important for a day trader to limit the number of trade he/she took in a day.
It's not all about limiting it alone, an experienced trader must know when to stop or continue in trading each day because there are times where it may look more difficult to realize something better from the signals seen but immediately after some minutes or lately in the day, things can suddenly change for good and better that may warrant taking another trade for the day which may be the most profitable one of it all.
* Lack of trading plan-- develop a strategy an stick to it, do not ever enters a trade blindly, if not the market will remove you blindly.
