ChrisW,
If the chart does not reflect all the movement in price during a given time frame (1, 5, 15 or 60 mins), it is a line graph which does not seem to suit your requirements. You it will seem, require a candlestick chart that will better reflect the information you want.
This simple exercise should answer your question :-
Open your chart as usual and open a candlestick chart alongside it (all criteria should be the same apart from one being a candlestick); now sit back and watch as the price moves.
