Set a stop-loss so you can go to work. But, be aware, if you don't move your setting, there will be an accumulation along support lines and they are targets for short sellers. I prefer to buy based on trends and put two bids in. One is the purchase along a support level and the other is where I'd like to average down along the next lower support level.

Look at a stock with falling prices and pay attention to the candle pattern at the bottom of a support level. Notice the quick drop and rebound. Change your setting to a minute or five minutes and look at the up and down volumes. Here is a quote from another site.

"On a daily basis, shorts use computerized trading to control the direction of the share price. At opportune times, the shorts overwhelm the buyers (bid price) of the stock by selling short large number of shares to drive the share price down and to eliminate the buyers for the stock at that given time.
Now the shorts can buy back some of the shares they have shorted at lower prices including some shares where longs have put stop-loss sale orders to protect against downside losses."
