MA, I did actually use a small account with real money to trade using purely Armstrong's predictions. I made a gain of 600% in 2 days before blowing up on a gap that went the wrong way on 0 day SPX options. Each trade was all in. It was excessively stupid, but an interesting experiment nonetheless. Of couse, it would be difficult to ascern validity with such a small amount of time and virtually no risk management. Had I used normal weekly options, I would have ended up with a gain. My own trading style is quite different, and I do not use the indexes.
So shall we claim success on the 600% in 2 days, or should we claim a failure on a blow-up after that?
My point here is that whether it's your performance or Armstrong's performance, it needs to be measured with a pre-defined criterion.
If we define gain as equal amount of trade entered on a daily basis, then based on that 3 day performance, that would average out to be (600%+0%) / 3 = 200%, not bad at all.
If we define gain as accumulative continual re-investment of the capital back into successive trade, then you would get -100% return at the end, which is not good at all.
Figuring out different hypothesis on Armstrong's writing to be tested will actually help one to sort out the best thing that one can glean from his confusing writing, and hone in the trading strategies. It is certainly possible that there is something that can be fished out from Armstrong's trading experiences for real profits. Unfortunately, I feel like it's far easier to look at MACD, RSI, Moving Average, and other technical indicators. They are just black and white and well-defined. I don't need to twist my brain around, and try to figure out that is the dip before the slingshot coming or not, or is this the dip, or ....
