To create candlestick chart click on the candlestick chart button on the menu and provide OHLC and Volume Data.
You can also right click on the chart to add any number series and annotate patterns on the candle stick charts. Its pretty self-explanatory overall and MarketXLS will prompt you to select series with annotations and patterns.
A pattern series only has binary ata. That means if the pattern value is 0 it means there is no pattern and if it is 100 or -100 it means there is a pattern. Charts can be maximized to full screen and they automatically adjust dates etc depending on size of the area.
