It works on any instrument on any time frame. That is what makes it robust. You can trade bonds, oil, gold, e minis, softs, basically anything that trades. This is pure support and resistance. It is competitive because it is a breakout retest trade and they are often the best entries with the best risk reward. Market makers and institutions will spend massive capital to "get: to these prices. Read Trading and Exchanges by Larry Harris to get more insight into why this is true. There are PDF copies on the net.
I pulled up a weekly chart to illustrate. Look at the low from Friday. Scary good for a swing trader.View attachment 202450
I believe that it could be an edge, but I will need to develop a backtest to confirm. Without testing, I suspect that this is a form of momentum that will only work in highly liquid factors, not alphas of individual stocks that tend to be mean reverting on most timescales. I expect that the support and resistance levels identified by the local minima of the short SMA are not very important and this aspect could be replaced by many other measures of relative value and work just as well.
Again, definitely appreciate you sharing and I will give a look to that PDF you mentioned. Cheers
