What does a candlestick show you? Each one shows the open, close, high and low, right? For price to move down, there must be more sellers than buyers, correct? The inverse is true for price to move up, in that there must be more buyers than sellers, right?
So for a low price to be set, and then the bar close higher, wouldn't there need to be more buyers than sellers to move the price up from the low to where it closes?
As for bouncing off the page, a price is only set when there is a transaction meaning there needs to be a seller and a buyer. If no one is selling, then it doesn't matter how many buyers are wanting to buy - the price won't move. So for a bar to open, price falls, and then climbs back up means there must be more buyers than sellers for the duration of that bar.
Edit: Also looking at your chart, it seems that most tails are only 1-3 pips long. Hardly huge moves in my opinion.
