2. Only trades eligible to set the 'Last' price are included in trade data. This includes (but is not limited to) Regular and ISO condition trades.
   
   Unless specified as a 'special condition' trade in the chart legend, out-of-sequence trades and other trade types not eligible to set the Last price are not included in the data.
   
   
3. All timestamps are exchange timestamps.
   
   
4. Elapsed time shown in the upper title of the chart will always reflect the Elapsed time of the exact chart sequence being displayed.
   
   
5. Total Quotes and Total Trades in the upper title of the chart will always reflect the total quotes and trades from all exchanges (for the exact sequence being displayed). Individual exchange statistics are shown in each chart legend. If exchanges are filtered out of the display (for clarity), the sum of the exchange numbers may not match the sum of the total numbers.
