Some traders (like myself) only generate a couple of signals in a day. The signal may be as brief as 1 Tick at the top or bottom of a bar. It is hard to keep focus for an hour or two between trades and then to have maybe, a couple of seconds to put everything into context before deciding whether to enter the trade or not. When I write a strategy in NinjaScript, I always have a "Heads Up" area that is designated by a plot (eg. draw arrow or change background color) or and audible alert or both. An example would be in a trending market, you determine that a possible pullback has begun. This gives me time to focus my attention. Especially if you monitor multiple markets.
So, a node with an option for audible or plot outputs or both, that could be toggled at certain points in the logic template would be very beneficial.
