oh it is from my TD Ameritrade setting. I place the Tickers that have High Chatters on List then I attach to it specific instruction, like High sell volume, or buy or unusual volume.. Then I watch that stock when I get the alert and then, see the chart and the filings and then wait for the move to come and I am in and out with that move.. The waiting sometime may be 1-3weeks.
This kind of trading is slow, and you may not trade a lot and if you whole income is based on what you make out of trading then it may not be for you. But it works good for me, since I have a day job.. But I sometimes do day trading but I really like short term like 1-3 or 1-6month holding..
I hope that answered your Q.
