HMA ALMA moving average combination for simple momentum trading

The gold line is the 100 day Hull moving average based not on price but on the ALMA (default settings). Works nice on the 1 hour chart too. It's not a perfect buy/sell line as you can see in some of the sideways moving price action, but generally, if you just used this line to buy when price closed above and sell when price closed below you would be doing pretty well. Shorter trends just need a shorter setting for the Hull, like 50. The ALMA is not a bad moving average, buy/sell line either, but as the basis for the HMA it gets even better. Maybe successful trading can be this simple?
