Last time I heard "Fulcrum" was early 90s, can't remember that guys name or system.
Let's flip the situation, if you made a well back tested viable system that made profitable weeks day trading, would you waste you time selling a system for $700 bucks or would you spend you time trying to become that much better of a trader? If you don't know how to program, it will take you longer to back test, and you don't have a clue if developer back tested this honestly or how he back tested it, and when volatility changes, unless you know enough about trading, you won't know how to adapt. Times I have bought systems, I would back test the hell out of it, and they never came close to my performance tests and always returned, too bad I didn't know how to program in the 80s as all that crap was useless systems.
Volume in stocks is traded differently than day trading Futures Indexes, which is a hedge of stocks. I never heard of using "Delta" day trading the ES, but does sound like a catchy name, only Delta I know has to do with options, further away from 50, possible more risk.
If ya going to pop for $700, ask for their brokerage statements for past three years. Watch for all the excuses.
