Draft copy
It does not decide. It measures.
After a session, there is no way to reconstruct what you were looking at when you decided. Tools display in real time, then keep nothing you can work with.
Alpha Trading Tool builds add-ons for NinjaTrader 8. The main one is an instrumented order book: seven measurements recalculated continuously. None of them tells you what to do.
Everything is recorded. One line per event, one continuous series per second. And the session reloads: replay it, place your own orders in it, and the measurements recompute on the real book data.
What it does not do
It does not replace a method. You need one already: the tool exists to check it, not to provide it. If you are looking for a system that decides for you, this is the wrong place.
