Coinigy allows users to display their current buy/sell positions and past trade history overtop the chart you are currently viewing. To enable this feature, right-click within the chart area to bring up the charting menu.

Scroll down and the two bottom options will allow you to show order history and current open orders.

Selecting the 'Show Open Orders' box will display your current positions and checking the 'Show Order History' box will show your past trade information.
