Fast Candlestick Charts
=======================

TradeTide draws candles with a small number of Matplotlib collections instead
of creating one artist per bar.  This makes the visualisation practical for
large intraday datasets.  By default, the renderer aggregates data to no more
than 2,000 visible candles while preserving each bucket's OHLC values.
