How do I use the 1OP indicator to day trade S&P 500 futures?

We look for deep troughs and big spikes. Those signal crosses produce the strongest bullish and bearish reversals respectively. The indicator is predictive (not reactive) and it is true 80% of the time. There are divergences when the market is in a strong directional trend and this happens 20% of the time. These divergences are also very powerful and we know when to look for them. There is an entire section about 1OP in Tutorials. I suggest you watch those videos.
