I have a chart for you, but running into some scheduling conflicts. Here is a little to chew on until I complete the chart. I want it to be retro back to first of Dec 2018.

Push is an intermediate-term trend indicator, smoothing out the noise of price fluctuations. I think of it as an intelligent moving average Responsive to both momentum and volume. As a rule, momentum will change direction before price, and can be used to forecast reversals. Looking at past Push signals, they are very wide apart. And fits well within TSP IFT rules.
With all it’s intelligent it will still be late. You will not get in at the exact bottom, nor exit at the exact top, but you will profit from the majority of the market moves. And it will have clear buy and sell signals.

Most people will say the Push is too slow. I predict most observers will get inpatient and not follow it. I think it has much merit, especially in bear markets.

Pull is more responsive to the market. A shorter-term trend indicator, smoothing out some of the noise, but still has many whipsaws. Extreme volatility with wide price fluctuations can give it a conniption fit. It tends to work best in bull markets, (when the Push is up-trending)..

Strength essentially is a comparison of the closing price of each of the funds. Each fund has a 0-10 strength range. It is an oscillator. It will never truly mimic the fund's actual price action. But for Strength, all that matters is that it has a higher number, or continues in the direction of the primary trend.
