Within MT4 itself:
For trade history display, first open a chart. Then in the Terminal window, click on the Account History tab. Select any order with the same currency pair as your window, and drag-and-drop it onto the window. If you want ALL orders for that currency pair, hold the Shift key while you drag-and-drop one order from that pair, and it will display all the orders.
There is also a really good script posted on another forum that does this with lots of nice features.
