Most exchanges provide basic charting tools.
However they are often incomplete.
There isn't many applications to look at:
Tradingview is the most complete.
By default it shows you Apple's graph.
Click on "AAPL" (upper left corner), write the desired pair.
You have an option for each exchange.
Right at the pair selector, you can select the timeframe.
By default it's on D, for "daily." It means each candle will represent the price action for a whole day.
A candle contains the OHLC of the selected timeframe (1 Day here):
Note how the open and close is not the same for green and red candles.
The lower and upper thin lines are called the wicks.
All timeframes follow the UTC timezone.
On a non-log chart, a move from $8000 to $10000 (+25%) will look as big as a jump from $10000 to $12000 (+20%).
To correct that, use the "log" option, at the bottom right corner.
