The Trade From Chart indicator for NT8 allows placing orders with a keyboard + mouse combination on a NinjaTrader chart, without having to use NinjaTrader’s fiddly right-click menu.

Select from indicator properties what key you want to use plus mouse click

You can select from the left side of the keyboard or the right side of the keyboard the  Shift or Alt key plus mouse click
