Symbols HUE, NGE, RBE, HOE, PLE, and NGH can be compressed, which means that ticks can be viewed in a quantity different from the exchange default. The default value for compression is five. Click the compression button to turn compression on and off.
Data is aggregated in the opposite direction of the market. Bids are aggregated down, and asks are aggregated up. The daily high price is rounded up, and the daily low price is rounded down.
Actual ticks, and not compressed ticks, are used for the offset value for stop limit orders. Order types are also determined by actual ticks.
Orders with fixed prices are visible.
