### <summary>
### Algorithm demonstrating custom charting support in QuantConnect.
### The entire charting system of quantconnect is adaptable. You can adjust it to draw whatever you'd like.
### Charts can be stacked, or overlayed on each other. Series can be candles, lines or scatter plots.
### Even the default behaviours of QuantConnect can be overridden.
