When quickly needing to get out of a position, let's say in this example the order size is 45,450.
If the last Order qty size I chose for another pair was 28,570, when I am trading from the chart in NT8 and right-click in the chart to set a buy limit, instead of it matching the current trade in progress on that chart, the size irt chooses in the one in the Order qty box, from a different trade.
This is is not very smart or well thought out. It should read the current position of the trade in that chart, and match that by default.
