The Refresh Interval 'Update' will monitor the price stream and update your trading screen as soon as new information arrives, This will reduce CPU usage on slower markets, and still saves a few milliseconds even when betfair is publishing market updates at their maximum speed.
A setting of 300ms - 350ms will be sufficient for most purposes. If the market is particularly volatile then a faster setting can be selected.
Further fine tuning of your communications settings can be achieved via the main settings editor.
If you untick the refresh check box above, all prices will be frozen. If you want the latest prices then ensure 'Refresh' is ticked.
